SGS Testï¼Â The test result complies with the RoHS directives 2002/95/EC and its subsequent amendmentsï¼ÂÂit has passed SGS Inspection regarding the related REACH required quality standards.
Properties: It is of excellent compatibility with rubber compound, makes the rubber compound with more plasticity and fluidity without bloomingï¼ÂÂcan improve the elasticity and anti-tear strength of Sulfur Colloid ,lower the temperature, shorten the cycle in the mixing or plasticizing process,showing good effect on the improving of measure stability and yield, no bad effect on the bonding between metal and fiber.
Applications: It is one muti-functional processing additive for rubber products, suitable in the internal mixers for both natural rubber and synthetic rubber such as BRãÂÂÂÂSBRãÂÂÂÂNBRãÂÂÂÂEPDM. When used as the additive for extrusion, it can improve the die swell ratio and the quality of final products ,and reduce the temperature of extruding process.
Usageï¼ÂÂDosage:2-5phr, may be punched when plasticizing the raw rubber or punched with other additives at the first phase of mixing process.( for multistage mixing process it can be added after carbon black filling)
Packing: composite paper bag, 25kg.
Remaks: At present,ZnFA has passed the SGS inspection complied with REACH.
