Grain shape and surface roughness are indicatedto codetermine the abrasionresistanceofthefilm. Further, the ar film with triangular grain andmoderate roughness shows good abrasion resistance.
Optim insulation is a hybrid material that combines the biostability and flexibility of high-performance silicone rubber with the strength, tear resistance and abrasionresistance of polyurethane, to provide increased durability and flexibility.
