  Pyrathane® Materials

Download Spec Sheet

Pyrathane® 83ASD is a polyester-based polyurethane which is identical in appearance to our 83A Pyrathane®. 83ASD is formulated to provide clean, permanent ESD (electrostatic discharge) protection and is humidity insensitive making it applicable for electronic component handling and other static intolerant applications.

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

As the modulus of Pyrathane® 83ASD 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%.
When considering 83ASD 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).
