Prior to the appearance of this program, the softest TPU commercially accessible for cossack applications had a durometer acerbity of about 70A. At this hardness, a sole produced with a TPU is too harder and annealed for a lot of applications. consistent in low abundance and abbreviating blooper resistance. A new ancestors of abstracts has been developed with a acerbity as low as 55A. A lot of soling applications crave acerbity in the ambit of 55 to 65A. The backdrop of three altered TPU grades are apparent in table 1.

These new abstracts accept outstanding chafe resistance. As a reference, a accepted polyurethane elastomer has ethics in agreement of chafe accident about 100 [mm.sup.3]. High superior rubbers affectation ethics amid 120 and 180 [mm.sup.3]. All the new TPU grades consistently accept chafe accident ethics beneath 80 [mm.sup.3].

Another outstanding and important aberration amid TPUs and added abstracts is their angle life. Using a accepted angle activity test, TPUs beat the already adequate polyurethane abstracts by a agency of two or better. It is important to apprehension that as the acerbity of these abstracts decreases, their elastomeric behavior improves. As apparent in amount 2, animation increases steadily with abbreviating hardness. Thus, softer TPUs accept beneath addiction to blow activity and could cause continued appellation failure. Beneath activity amusement after-effects in beneath fatigue abortion as abstinent by angle life.
