Properties:

Used as the Activator of vulcanization accelerator of rubber products, the thermal stabilizer of PVC, also as the best physical peptizer of natural rubber, is a kind of multifunctional rubber processing auxiliary , can be used in vulcanized rubber to improve anti-reversion properties and heat resistance, with both internal and external lubrication and dispersion function,, Can be used in the mastication and mixing process of natural rubber and synthetic rubber. This product is excellent compatible with rubber, not plastic spray with dual functions of lubrication and peptization. Can improve the processing of rubber, improve the passing rate and dimensional stability of rubber products, reduce energy consumption and improve the efficiency of mixing. Used in rubber processing, can improve the extrusion Properties of rubber, the extrusion speed and smoothness of semi-finished. Dosage: Activator 3 ~ 5phr, Processing aids 2 ~ 4phr
