FLEXIBILITY OF FLAT DRIVE BELTS and REGULATOR TAPE
Flexibility as determined by the beam flex test
Dymetrol flat drive belts are 2 to 3 times more flexible than oriented materials at -30°C

Dymetrol belt compositions exhibit relatively low change in flex modulus over a wide temperature range compared to most plastics. Actual flexibility of Dymetrol belts is a function of composition, as well as cross section and perforation pattern. Flexibility is increased as the thickness and width are decreased. Using a cantilever beam stiffness test, a 2000 series un-punched belt with a geometry of .60 in. wide by .070 in. thick and a load span of 2 inches will deflect 1 inch under a .95 lb force at 23°C(ASTM test D747).
