1 密度：0.55-0.6 g/mm³，硬度：65-70℃
Density: 0.55-0.6 g/mm³, Hardness: 65-70℃
Material: PU elastomer which has very good abrasion resistance, buffering, energy absorption, tear resistance, high elasticity, hydrolysis resistance, acid resistance and cold resistance (details are as below). The scrap PU can degradate by itself, which is good for environmental protection.
