ELASTABRASION - ELASTOMER ABRADER

Our ElastAbrasion has been designed with the James Heal unique product signature and has been produced completely with the user in mind. We have combined the James Heal technical and performance expertise, with intuitive design and operation to produce the most cost effective, ergonomic and user friendly instrument.

Features and Benefits

 Air jet cleaning system  Automatic controllers ensure efficient use of compressed air  Specially designed sample holder  Hinged lift up top plate for easy access  Versatile and intuitive key pad user interface  Quick lock clamp rings for easy mounting of abradant  Unique ‘soft lissajous’ pattern  Cabinet to contain debris  Facility to attach a vacuum hose  User safety – Instrument will only function when the cabinet is closed  Variable speed  Changeable number of rubs  Standard 18 months warranty  Test materials - abradant required only  Negates the need for reference rubber  Engineering support  Applications support  Operator training is available through James Heal  Tested and approved by Volkswagen  Multi directional abrasion reflecting real life usage  Reduction in cost compared with the rotary drum abrader  Increased productivity – 4 specimens tested simultaneously  Approximately 50% reduction in variability of results compared with the rotary

drum abrader

Air Jets

Each holder is bordered with 3 equidistant air jets supplying a constant 1 bar of compressed air pressure. Any elastomeric debris is blown away from the abrading table, removing the potential for interference with any further abrasion of the specimen.

Specimen Holder

The specimen holder is designed to hold an elastomeric specimen 15±0.2mm X 15±0.2mm with a maximum thickness of 12mm. The packing shims are used to create a protrusion of 2±0.2mm. The collet is held in a fixed position within the holder to avoid movement.

Clean Environment

ElastAbrasion is enclosed in a cabinet;

this ensures that the debris produced by the abraded specimens is contained.

Two vacuum attachment points have been included in the cabinet design.

A vacuum hose can be attached to either side of the cabinet to extract any fine airborne debris.

The vacuum can be powered through the ElastAbrasion by fitting an IEC connector to the vacuum wiring and plugging into the instrument; it can then start and stop automatically with each test.

Scope of Application

ElastAbrasion has been designed for determining of the abrasion resistance of elastomers

and thermoplastic elastomers.

The instrument conforms to PV 3984, a standard used in the motor industry, developed for engine mounts.

ElastAbrasion allows 4 elastomeric samples to be tested simultaneously.

It eliminates the use the traditional BAM reference rubber to verify the abradant, as each piece of sandpaper is discarded after one use.

The user does not need to attend the instrument to brush away the debris as the compressed air continually blows this away.

Users will see approximately 80% reduction in cost and time over traditional methods, and reduced variability of results.

There is scope to develop test methods appropriate for tyres and shoes, or any other material that currently requires the use of the rotary drum abrader, or other similar methods.

Our innovation team welcome any other requests for further development of this instrument and accessories.
