HYTREL®
Hytrel
is a copolyester elastomer that demonstrates excellent low temperature
flex characteristics as well as the ability to perform at a
considerably higher temperature level than our standard 83A
PYRATHANE.
Temperatures as low as -40 F and as high as +200 F are possible.
Hytrel has excellent resistance to a wider variety of chemicals
allowing its use in applications urethanes could not tolerate.
Belts of both flat and round configurations can be manufactured
of the Hytrel material.
As the modulus of Hytrel is considerably higher than our 83A
material, we would recommend an initial stretch of approximately
5% which still provides more tension than our PYRATHANE 83A.
Hytrel can sometimes provide necessary low temperature flexibility
or chemical tolerance which may offset its poorer abrasion resistance.
When considering Hytrel for your application, only the general
information provided in our product brochure will be applicable.
Please call us with any questions.
This
material is a more specialized version of our PYRATHANE products
family and therefore a modest upcharge is associated with it.
