Technical features
Si-50 is a coupling agent masterbatch successfully applied to rubber. It has higher dispersion and compatibility with the rubber, and is friendly to the operator and the environment. There is no material loss during operation and no dust and liquid leakage, so the mixing efficiency can be improved and the energy consumption can be reduced. Main uses: 1. Multifunctional rubber additives, suitable for colorless or light-colored high-performance special requirements of rubber products, improve filler reinforcement ability, is an important part of the vulcanization system to improve cross-linking performance, the carbon black and white carbon black and other fillers and rubber are well combined to increase modulus and wear resistance of products. 2. Balanced vulcanization, the four sulfur atoms in its molecule and sulfur participate in the polysulfur crosslinking reaction, and the crosslinking speed of the tetrasulfanyl group is roughly the same as the sulfur reversion speed in sulfur vulcanization, so it can resist reversion and form appropriate anti-reversion compound. Its dynamic bending properties (such as heat generation, crack elongation, etc.) have been significantly improved. 3. The effect of vulcanization and promotion of activity, the effect of enhancing or changing aging in the vulcanization device.
Application
This product is widely used: tires, rubber soles, rubber rollers, tape and other rubber products, can improve the wear resistance of products, tensile strength, tear strength, increase thermal aging, improve bending, but also can improve the mixing processing performance, sulfur denaturation performance, reduce energy consumption.
