1.High temperature resistance--It can continuously work under-70 to 260＆#8451;. 2.Permeability--It can avoid wasting heat and improve drying efficiency for it's permeability. 3.Chemical resistance--It can resist all most of chemical medicines. 4. Adherence resistance--It can easily remove all kinds of adhesives such as resin,paint and chemical medicine. 5. Good flex fatigue resistance--It has high tensile strength and excellent flex fatigue resistance. It's better for small wheels.
