Characteristics Vulcanizator HVA-2(PDM) is soluble in dioxane, tetrahydrofuran and hot acetone, but insoluble in petroleum ether, tetrachloromethane, benzene and water. Its specific gravity is 1.44.
Applications HVA-2 is vulcanizator, scorch retarder, tackifier or co-curing agent of peroxide system in rubber processing. In NR system, HVA-2 combined with sulfur can prevent curing reversion, improve heat resistance and anti-ageing properties, reduce thermogenesis and increase adhesion force between rubber and tyre cord and modulus of vulcanized rubber.
Packaging Coextruded paper bags lined with plastic film, net weight 25Kgs/bag.
Storage Store in a cool, dry, well-ventilated area away from sunlight.
Safety and toxicity Refer to the MSDS.
