In today's world, the demand for high-performance materials is on the rise. Industries such as automotive, construction, and electronics require materials that can withstand harsh conditions and provide optimal performance. This is where Evonik Degussa Si-69 comes in. Produced by Ningbo Inno Pharmchem Co., Ltd., this product is a reliable solution for maximizing performance in a range of industries.

Evonik Degussa Si-69 is a type of bis(triethoxysilylpropyl)tetrasulfide, also known as Bis-[γ-(triethoxysilyl)propyl]-tetrasulfide, Bis[3-(triethoxysilyl)propyl]-tetrasulfide, Bis(triethoxysilylpropyl)tetrasulfide, or 3,3-tetrathiobis(propyl-triethoxysilane). It is a coupling agent that can improve the adhesion between dissimilar materials, such as rubber and silica, or rubber and metals. This makes it an ideal ingredient for rubber compounds used in tires, hoses, seals, and other applications.

Evonik Degussa Si-69 is not the only coupling agent available on the market. Other popular products include DOWSIL Z-6940, Shin-Etsu Japan KBE-846, and Momentive Silquest A-1289. However, Evonik Degussa Si-69 stands out for several reasons. First, it is produced by a reliable supplier, Ningbo Inno Pharmchem Co., Ltd., which has a state-of-the-art factory and a team of experienced chemists. This ensures consistent quality and timely delivery of the product.

Second, Evonik Degussa Si-69 has a unique synthetic route that results in a high-purity product. The process involves reacting 3-chloropropyltriethoxysilane with sodium polysulfide, followed by hydrolysis and distillation. This method eliminates impurities and ensures that the product has the correct molecular structure and sulfur content. The purity and consistency of Evonik Degussa Si-69 make it a preferred choice for manufacturers who require precise control over their formulations.

Third, Evonik Degussa Si-69 has excellent performance characteristics. It can improve the tensile strength, tear strength, and abrasion resistance of rubber compounds. It can also enhance the dynamic properties of tires, such as rolling resistance and wet grip. Furthermore, it can reduce the heat build-up and improve the durability of rubber products. These benefits translate into longer-lasting and safer products for end-users.

Finally, Evonik Degussa Si-69 is cost-effective. Its dosage level is typically in the range of 1-5 phr (parts per hundred rubber), depending on the application. This means that a small amount of Evonik Degussa Si-69 can go a long way in improving the performance of a rubber compound. Moreover, its high-purity and consistency can reduce the need for additional testing and adjustments, which can save time and resources for manufacturers.

In summary, Evonik Degussa Si-69 is a reliable and effective coupling agent for maximizing performance in rubber compounds. Produced by Ningbo Inno Pharmchem Co., Ltd., it has a unique synthetic route that ensures high-purity and consistency. It has excellent performance characteristics and is cost-effective. By choosing Evonik Degussa Si-69, manufacturers can enhance the quality and durability of their products and meet the demands of their customers.
