Download Spec Sheet

Pyrathane® 83AUV is a polyether-based polyurethane which is identical in appearance to our 83A Pyrathane®. 83AUV is resistant to degradation due to ultraviolet light and in addition, better tolerates high humidity at elevated temperatures making it applicable for outdoor uses.

Belts of both flat and round cross sections can be manufactured of the 83AUV material.

As the modulus of Pyrathane® 83AUV is slightly lower than our 83A material, we would recommend an initial stretch of approximately 12-1/2% which is somewhat higher in order to compensate.

This higher initial stretch will provide approximately the same tension as our 83A material at 10%.

We find that 83AUV is especially well-suited for outside applications, even in subtropical and tropical areas, where other polyurethanes could not normally be used.

When considering 83AUV for your application, and when an initial stretch of 12-1/2% is utilized, other general information provided in our product brochure will be applicable.

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