performance
Product performance: low glass transition temperature, high elasticity, high flexible performance is good, wear-resisting performance is good, after the loss of small, small heating, and other rubber solubility good, catch focus on small, poor wet resistance, tensile strength, resistance to tear strength is low, anti-bending of excellent abrasion resistance, good sex.
