Product Description

Description: RC2557-A,R 72606 are solution-copolymer using organic lithium as initiator by anionicpolymerization method in varsol consisting of styrene and butadiene. They are non polluted typestyrenebutadie/Mooney viscosrrow molecular weight distribution, high cis content, good abrasionresistance, low rolling resistance, can solve the problems of weak wet skidresistance of BR and high rollingresistance ofSSBR. They are ideal materials for tire tread.
