Elastomeric Material Views

General Goods

For virtually every O-ring end use, the selection of elastomeric material is contingent upon a number of design factors such as: dynamic or static application; chemical compatibility; the O-ring's ability to resist pressure, heat, cold and friction, and consideration of material availability and cost. (In addition to design factors, of course, one must also consider the nature of the installation, the use of the product and the kind and degree of maintenance that may reasonably be expected.)

Every batch of elastomeric material is tested in our laboratory and a tracking number is assigned so each product can be traced to its raw materials. Physical properties are recorded and a test specimen is saved for future evaluation. Using state-of-the-art computer controlled testing equipment, we perform a full range of ASTM tests:

The present invention may be used specifically and preferably in systems, in which at least one extruder is used to feed extruded elastomeric material, normally in rope form, to at least one unit for applying the extruded elastomeric material to a rubber-covering surface of a toroidal body, such as a vehicle tyre carcass, rotated about a respective axis, to form a cover layer on the rubber-covering surface, e.g. a layer constituting a component part of the tyre.

Elastomeric Material Selection Guide The following information is provided as a starting point in the process of selecting an appropriate elastomeric material for specific applications. This information has been collected from various sources and is believed to be reliable, however, no warranty to its accuracy or completeness is implied or expressed. The final determination of the suitability of a material to an application is the sole responsibility of the user.
