Download Spec Sheet

Pyrathane® 92A is an FDA 1680 and 2600 compliant polyester-based polyurethane which is clear in coloration. It is extremely tough and durable, exhibiting high tensile strength as well as excellent abrasion resistance.

Because of greater abrasion resistance, Pyrathane® 92A is especially well-suited for applications where higher amounts of wear might be expected.

Belts of both flat and round configurations can be manufactured of this material.

We recommend an initial stretch of approximately 7-1/2%, which works well on most applications. This stretch will provide approximately 50% more tension than our 83A material at 10%.

Polyurethanes of higher durometers usually will exhibit shorter flex lives than their softer counterparts and our Pyrathane® 92A is no exception. The stiffness of this material also dictates larger pulley diameters.

Pyramid Inc. has materials available that have advantages such as higher co-efficients of friction or for use where static dissipation is desirable or where ultraviolet light is a concern.

Ambient operating temperature limits are -10° to +150° F (-23.3° to +65.6° C).
