DOWSIL Z-6940: Enhancing Performance and Durability of Rubber and Tire Products

Rubber and tire products are used in various industries, including automotive, construction, and manufacturing. These products are expected to have excellent performance and durability, especially since they are subjected to harsh conditions such as high temperatures, abrasion, and mechanical stress. To improve the properties of rubber and tire products, manufacturers rely on various additives, including silanes such as DOWSIL Z-6940.

DOWSIL Z-6940 is a versatile silane coupling agent that is widely used in the rubber and tire industry. It is also known as Evonik Degussa Si-69, Shin-Etsu Japan KBE-846, Momentive Silquest A-1289, Degussa Si-69, and ShinEtsu Z-6940. Its chemical name is Bis(γ-triethoxysilylpropyl)tetrasulfide or Bis[3-(triethoxysilyl)propyl]tetrasulfide or Bis-[γ-(triethoxysilyl)propyl]-tetrasulfide or Bis[3-(triethoxysilyl)propyl]-tetrasulfide or Bis(triethoxysilylpropyl)tetrasulfide or 3,3-tetrathiobis(propyl-triethoxysilane).

DOWSIL Z-6940 is manufactured and supplied by INNO Specialty Chemicals, a leading company based in China. This silane coupling agent is used to improve the performance and durability of rubber and tire products by enhancing their adhesion, reinforcement, and crosslinking properties. It is particularly effective in enhancing the properties of silica-filled rubber compounds, which are used in high-performance tires.

One of the main benefits of using DOWSIL Z-6940 is its ability to enhance the adhesion between the rubber and various substrates, such as steel, textile, and other rubber compounds. This is achieved by forming strong chemical bonds between the silane and the surface of the substrate, which improves the wetting and spreading of the rubber. As a result, the rubber compound has better mechanical properties, such as tensile strength, tear resistance, and abrasion resistance.

Another benefit of using DOWSIL Z-6940 is its ability to improve the reinforcement properties of the rubber compound. This is achieved by crosslinking the rubber chains with the silica particles, which increases the stiffness and modulus of the compound. As a result, the compound has better handling, stability, and fuel efficiency, which are important factors in the tire industry.

Moreover, DOWSIL Z-6940 is also effective in improving the crosslinking properties of the rubber compound. This is achieved by reacting with the sulfur-containing vulcanizing agents, which form strong chemical bonds with the rubber chains. As a result, the compound has better heat resistance, aging resistance, and fatigue resistance, which are important factors in the durability of rubber and tire products.

Overall, DOWSIL Z-6940 is a highly effective silane coupling agent that can enhance the performance and durability of rubber and tire products. Its versatility and effectiveness make it a popular choice among manufacturers in the rubber and tire industry. With the increasing demand for high-performance and durable rubber and tire products, DOWSIL Z-6940 is expected to play a crucial role in meeting these requirements.
