Bis(triethoxysilylpropyl)tetrasulfide CAS:40372-72-3
GW361
When used in rubber products alone, it has the following functions:
As a coupling agent for non-black fillers.
Maintain vulcanization balance to increase reversion resistance.
As a vulcanizing agent, it obtains good heat aging properties.
Coupling Agent – Add a small amount of this product (0.5~1.0 phr) to clay filler, or add a small amount of this product (1.0~4.0 phr) to silica pigment, this product can combine non-carbon black pigment and artificial rubber Well bonded and able to increase modulus and improve wear resistance.
Equilibrium Vulcanization - There are 4 sulfur atoms in the molecular structure of this product. At vulcanization temperature, this product and sulfur participate in the reaction process of polysulfide crosslinking. During the vulcanization process, the cross-linking speed of the tetrasulfanyl group in this product is roughly the same as that of sulfur reversion in sulfur vulcanization, so it can resist reversion and form an appropriate anti-reversion compound. This is called balanced vulcanization. Among them, the dynamic bending properties (such as heat generation, crack elongation, etc.) have been significantly improved.
Vulcanizing agent - Use this product and a thiuram accelerator to replace all sulfur in NR, SBR, NBR mixtures, the resulting product has excellent heat aging performance in addition to good coupling effect.
This product is a silane coupling agent with cross-linking and active catalysis in rubber products.
The theoretical basis of the action of this product is the coupling of the silane group in the molecule with the white carbon black and silicate structure in the non-black pigment. This is called a shrinkage reaction. The four sulfur atoms in the molecule can act as vulcanization/promoting activity, enhancing or changing the type of aging in the vulcanization unit.

This product is most suitable for rubber formulations using hydroxyl-containing fillers in double bond-containing polymers or their blends. Suitable fillers include white soot, silicate, chalk, etc.; suitable rubbers include natural rubber (NR), styrene butadiene rubber (SBR), isoprene rubber (IR), butadiene rubber (BR), nitrile Rubber (NBR) and ethylene-propylene-diene rubber (EPDM), etc. Silanes
tert-Butyldiphenylchlorosilane CAS:58479-61-1
GW367
Tert-butyldiphenylchlorosilane, also known as silane protective agent, is used to replace the active hydrogen in the silyl group (such as the hydrogen in the hydroxyl group, carboxyl group and amino group) to generate a stable intermediate; then, the other intermediates of the intermediate The group undergoes certain reactions; after the reaction, the silyl group is removed through a hydrolysis reaction, and the group originally protected by the silyl group is regenerated to synthesize some specific compounds. Due to the high conversion rate and even quantitative reaction of silane protection and deprotection reactions, it is widely used in organic synthesis, especially in drug synthesis.
tert-Butyldiphenylchlorosilane is used in the synthesis of p-benzophenyloxazole, a compound with antagonistic activity at thromboxane receptors, which is used in the treatment of circulatory diseases, angina pectoris and stroke.
This product can be used as a pharmaceutical intermediate and in organic synthesis
This product is a kind of silicon-based protective group; it is used for the synthesis of pharmaceutical intermediates or other macromolecules.
This product is a silylation reagent, used to protect alcohols and prepare silyl ethers Silanes
