Alkylphenol Disulfide Rubber Vulcanizing Agent Chemical Additives OF-7

OF-7 is a polymeric alkyl phenol disulfide, contains unique sulfur donors in the molecular structure, can vulcanize rubber in heated state,  typically used as nitrosamine-free environment-friendly sulfur donating body in the rubber compound formulations, can give excellent mechanical properties, heat aging resistance, excellent dynamic fatigue properties and good operational safety performance.

Application

OF-7 contains unique sulfur donors, can vulcanize rubber in heated state, giving non-blooming, high tensile strength, excellent heat resistance and dynamic fatigue properties, used as sulfur donor type vulcanizing agent for NR/SR. For the co-vulcanization of different polar rubber, such as NR, CIIR, IIR and EPDM, it provides excellent performance. Can be used in tires, gaskets, belts, automotive hose, damping products. Because containing alkylphenol groups, it has also excellent tackifying and antioxidant effects. Not producing nitrosamines toxic gas during vulcanization, it is an environmentally friendly additive. Reference dosage 0.5-5 phr.

Package and Storage

In paper/plastic combined sack with inner film bag, 25 kg net each. Store indoor, drying and ventilating, shelf-life 18 months.
