Products introduce: This product is made from ethylene device by-product carbon nine fraction as raw materials by thermal polymerization and system. Product appearance is light yellow to light brown flake or granular solid,transparent and gloss, with good solublity, mutual solubility, waterproof, insulativity. It has the chemical stabilizing property to acid and alkaline, viscosity adjusting and thermal stabilizing.
product usage: This kind of Resin has a good miscibility with natural rubber particles, and little affect on rubber vulcanization. It can play the role of anchoring reinforcement and soften in the rubber. Suitable for radial tyre contour requirements of the rubber products. Alternative rosin, synthetic hot melt adhesive. Also suitable for make other modified resin.
Packing,Storage and Transportation： N.W 25kg per PP woven bag with plastic lining. The packing can be changed by client’s requirements. It can be transported by truck, train and ship etc, but must avoid sunlight, rain-drenched, damp, hook, alkali and oxidant. The one-year period storage should be in ventilating, cool and dry area. This product is a non-dangerous chemical.
