Product Description Composition: Mixture of high molecular weight unsaturated zinc salts Appearance: Light yellow granules Density: 1.07 g/cm3 (20°C) Ash content: 13.0 ± 1% (850°C, 2 hours) Melting range: 85-100°C Vulcanizate staining property: None Application: As a dispersing and lubricating auxiliary agent, CUREKIND ST is the best physical peptizer for natural rubber. It is a multi-purpose rubber processing auxiliary agent. When applied to rubber, it can improve the reversion resistance and heat resistance of vulcanizates, and has both internal and external lubrication and dispersion functions. It can be used in the mastication and mixing processes of natural rubber and synthetic rubber. When used for rubber mastication, it can peptize natural rubber and isoprene rubber. This product has excellent compatibility with rubber, does not bloom, and has both peptizing and lubricating functions. It can improve rubber processing technology, increase the qualification rate and dimensional stability of rubber products, reduce energy consumption, and improve mixing efficiency. During the rubber mixing process, it can promote the dispersion of fillers and other auxiliaries, shorten the mixing cycle, reduce mixing energy consumption, and reduce heat generation of rubber compounds. When used in rubber processing, it can improve the extrusion performance of rubber compounds, increase extrusion speed and the smoothness of semi-finished products. Usage: It is recommended to use it in an internal mixer. Applications and Dosage: As a dispersant and lubricant for highly filled diene synthetic rubbers. It is especially suitable for compounds containing high-reactivity silica: tire treads, industrial molded products. EPDM, EPM, CPE (CM), HNBR: 2 ~ 3 phr NR, SBR, NBR, IR: 1 ~ 3 phr
