MACHINING Foam can be used in the fabrication of variety of artifacts using common
tools and machinery as recommended in this section.
General Rules When machining Foam with high-speed equipment, using carbide
tipped tools is recommended. Lower speeds usually work better and always use sharp tools to ensure smooth edges.
Cutting Sheets of Foam up to 3 mm thick can be cut with a utility knife. Table
and band saws, including routers, can be used to cut thicker gauges. Power shears or guillotines are not recommended. They can cause edges to be crushed.
Stamping and Stamping and die cutting are cost-effective methods for the efficient Die Cutting manufacturing of large quantities of pieces where edges require no
routed finish. For best results, it is very important to cut the material AT THE RIGHT TEMPERATURE (70-100 degrees F). As a rule the lower the sheet temperature, the less consistent the process and the edge finish. For complete instructions on die cutting, please call our toll free number on the back of this manual.
Note:
Avoid making shapes or cutting holes that require sharp corners because it creates a weak area that can be broken. Easing off these angles with a radius is recommended. (see illustration I)
Sawing For best results, use carbide tipped circular saw blades with a rake angle
of 0 degrees to 15 degrees and a clearance angle of 10 degrees to 20 degrees with a tooth pitch of .080” to .400”. Saw at a cutting speed of 8,000 to 12,000 feet per minute and a feed speed of 70 to 90 feet per minute. (see illustration 2)
When using band saws, high speed steel blades used for cutting wood or plastic are commended with 4 to 8 teeth per inch at a cutting speed of 3,000 to 5,000 feet per minute and a maximum feed speed of 40 feet per minute.
2 | P a g e
Drilling Holes Holes may be drilled through Foam using the same methods employed
for drilling wood. Carbide tipped drills are recommended with a point angle between 90 degrees and 110 degrees and with a spiral angle of 30 degrees. (see illustration 3). High feed and drilling speeds may hinder the efficiency of the drill by creating heat buildup. For best results, use sharp bits and lower speeds.
Routing and Milling Foam may be slotted, beveled, rabbeted, etc. with routers or shapers
commonly used for working wood. Carbide tipped cutters are preferred.
SURFACE TEREATMENT Foam is a versatile material suitable for a variety of graphic
applications ranging from signs to POP displays. Below are some helpful hints on how to prepare and use Foam for printing, painting, gluing, photo mounting and laminating.
Surface Preparation It is always a good practice to clean the surface of the material to
eliminate the possibility of any grease or dirt that may have contaminated the surface during handling. For best results, use Isopropyl alcohol or naphtha and clean lint-free cloth to wipe the surface. Avoid using paint thinners because they leave a residue on the surface that could interfere with the bonding of the paints, inks and adhesives.
Screen Printing Foam has a consistent and smooth surface that lends itself to the
permanent acceptance and retention of a variety of printing inks. One of the most commonly used methods screen printing. Follow the surface preparation instructions. It is always a good practice to test print before going into full production.
Note:
Mixing different brands of printing inks and solvents may reduce the longevity of the sign. A telltale indication is the premature cracking of the surface which is difficult to determine when first printed.
Scratches and dents will become accentuated when screen printed. Sanding down the affected area with a very fine sandpaper or using a

blow type heat gun is recommended to reduce the change of the scratch showing through the ink. Please refer to Table 1 for a list of pre­approved ink manufactures.
Painting In addition to screen printing, Foam also has the perfect surface for
paint adhesion. There is no need to prime the surface before painting. Most conventional tools and painting methods will work successfully with Foam. However, for best results, follow the surface preparation guidelines introduces earlier. The surface of Foam will accept acrylic­based lacquers, urethane and vinyl based paints. Please refer to Table 2 for a list of pre-approved paint manufactures.
For outdoor use, to minimize heat build up and possible deflection,
pastel colors, rather than darker colors, are recommended. Painting the entire surface with dark colors is not advised.
Varnishing Always follow the surface preparation instructions previous mentioned.
Air-dried varnishes are recommended. Due to the nature of Foam, over-baked varnishes are not suitable. Most available varnishes in the market will touch dry in 60 minutes and thoroughly dry in 24 hours.

Glues and Adhesives There are a variety of solvent-based glues and adhesives in the market
that can be used bonding Foam to itself and other materials. For best results, InteFoam sheets must be dry, clean and free of oil or grease.
MEK (Methyl Ethyl Ketone). THP (Tetra Hydro Furan) or common PVC
pipe glues work well. Make sure glue joints have a close fit tolerance. Spray adhesives work well for light duty applications such as mounting photographs and other lightweight graphics. Contact, rubber, epoxy and urethane based adhesives work well with specific non-PVC substrates.
PHOTO MOUNTING AND LAMINATING
Foam is a tough, abuse-resistant substrate that can be used for photo mounting and the transfer of film overlays. It has many advantages over known materials, such as MDO, cardboard and paper backed foams. Corners remain true during tough handling. It can be stripped, repositioned, salvaged and reused in case of an error. Once laminated, it can be worked using stand methods of further conversion.
There are many methods for mounting and laminating that vary according to the type of adhesive used and whether it is done manually or using presses. Pressure sensitive spray adhesives or transfer adhesive films with resin coated papers that can be peeled from the adhesive work well for photo mounting and laminating.
The use of a laminating machine may be required for removing air bubbles caused during the mounting process. To perform this function, it is recommended to use between 10 to 15 psi of surface pressure to prevent distortions of the photo or the laminate being mounted. Please refer to Table 3 for pre-approved adhesives for photo mounting and laminating.
Note:
Sheets largely covered by laminates, vinyl film, carpet, paints, etc., may deflect when exposed to direct sunlight or sustained heat due to the expansion and contraction differential of the covering material and the Foam substrate. Covering should be done with caution and due consideration of the environmental conditions. In-place testing is always recommended.

THERMOFORMING Foam is a thermoplastic. It becomes soft when exposed to
intensive heat. This characteristic gives the material thermoforming capabilities. However, since it is expanded PVC foam, it is important to know that it lacks the draw depth of solid PVC sheets. Heat bending, pressure and vacuum forming are among the methods that may be used to thermoform Foam. Depending on the method used, the optimum heating temperature of the sheet should range between 250 degrees F and 350 degrees F
Heat Bending Heat bending is a common process that does not require sophisticated
equipment. Most bending can be accomplished with strip or radiant heaters, hot air ovens, and, for thin panels, hot air welding guns.
Basic Premises:
Minimum radius of bend should be 3 times the sheet gauge.
(see illustration 4)
Heating time 30 to 50 seconds per millimeter of thickness. Leave at least 20 times sheet gauge for border when hot line
bending angles.
Heat both sides when bending sheets 5mm to 10mm. Always make sure material is cooled before using after bending.
Pressure and Both of these methods require the use of air circulating ovens capable Vacuum Forming of reaching temperatures between 260 degrees F and 280 degrees F or
radiant heat panels capable of reaching temperatures exceeding 700 degrees F. The usage of molds is required for the thermoforming process. These methods are ideal for consistent, high production projects require more elaborate details than hot wire bending.
Basic Premises:
Molds should not have sharp angles. (see illustration 5) Molds should have at least 5 degrees draft angles. Temperature should not exceed 750 degrees F for top heating
and 650 degrees F for bottom heating.
Heating time should be between 15 and 20 seconds per
millimeter of thickness
Sheets must be securely clamped to molds to minimize
shrinkage
Sheets must be completely cooled before removing from mold.
6 | P a g e
WELDING There are several methods for welding plastics. The most common are
butt welding and hot air welding or gas welding. Note that welds on expanded PVC foam are usually not as strong as those of solid PVC
Butt Welding Butt welding is recommended for gauges 4mm and over. This method
allows fusion by simply joining two ends together under pressure after ends have been heated to an optimum bonding state. This pressure must be maintained until the material is completely cooled. (see illustration 6)
Hot Air Welding Hot air welding is accomplished with the use of a hot air gun and a
welding rod. (see illustration 7) The temperature can be regulated and this method allows great flexibility. Rods made of Type I PVC are preferred, but Type II can also work well. Welding is accomplished by feeding the rod through the gun and applying pressure on the rod as the sheet and rod are heated simultaneously.
For best results, the temperature of the air at the tip of the rod should
be 680 degrees F. Welding pressure should be approximately 2 to 3lbs. depending on rod diameter. Under optimum conditions, welding 10 to 18 inches per minute can be accomplished.
INSTALLATION Foam PVC is a low-density material that can be compressed relatively
easily. When securing the material in place, make sure the clamping force is spread evenly over a large area.
All extruded products have grain determined by the direction of the
extrusion which is the length of the sheet. The grain direction offers greater flexural strength when compared to the cross grain direction. Because of this characteristic, make sure the grain direction is parallel to the floor when making flag-type signs.
Note:
Most thermoplastics tend to become hard and brittle in cold
temperatures just as exposure to wide variations in temperature and
7 | P a g e
outdoor direct installation to concrete or metal surfaces may cause
deflection. Please read the following instructions carefully.
Free Hanging Signs When installing free hanging signs such as aisle markers in
supermarkets, bookstores, and home centers, locate holes 1” or more from the vertical edge and at least ¾” from the horizontal edge. Use grommets to prevent wear and stress. The supporting chains should be installed at a 30 degree to 45 degree angle. (see illustration 8) If perfectly vertical chains must be installed, use a plastic or aluminum clip-on “U” channel and position holes as desired. (see illustration 9)
Fastening Ambient temperature should always be taken into consideration when
attempting to fasten Foam to walls, poles, frames, wood and other plastics. As a thermoplastic, InteFoam is susceptible to expansion or contraction when there are significant changes in temperature. Dark colors tend to absorb more heat when exposed to direct sunlight.
When using bolts or screw for mounting, it is recommended to drill
oversized or slotted holes positioned at least 1” from the edges in order
to compensate for this characteristic common to most plastics (see illustration 10) Grommets or a dab of silicone in the holes will create a
tighter hold.
To allow stress relief from expansion, bolts, and screws should only be
moderately tightened. Apply the coefficient of linear expansion from Table 4 to the total temperature swing differential to calculate your specific requirements.
Thread cutting and thread forming screws may be used to mount
lightweight objects to Foam. Use moderate torque pressure to avoid stripping the threads.

If wind shear forces are a consideration, using large diameter washers is
recommended to spread the load forces over a larger area.
WEATHERABILITY Due to the natural UV inhibitors in white Foam, it tends to
perform very well in outdoor conditions. Colors have the tendency to fade over time when exposed to direct sunlight. However, Foam colors perform the best in the industry. Several years of research have resulted in formulations that make Foam colors stand out. We recommend performing your own testing by putting Foam and other manufactures’ color chips, side by side, under the same environmental conditions. The results will astound you.
FIRE RESISTANCE conforms to UL94 V0, UL94 5V and UL48, which allows to be
used in the manufacturing of electric signs.
FORMULATION contains no lead or heavy metals in its formulation. Please refer PARAMETERS to Table 5 for Chemical Resistance Chart.
