Our company has built a dedicated production line workshop for double-terminated vinyl silicone oil, which has been fully upgraded and put into production. The production capacity has been greatly increased, the technology is better, and the quality is more stable. After the early product trial and small-batch production, it has been recognized by the trial peers and downstream companies. Now the equipment is upgraded, the production capacity is expanded, and the production is automated. The daily output of a single line can reach 15 tons. The viscosity is expanded to 15 viscosities such as 30/50/70/100/230/350/500/1000/2000/3500/5000/10000/20000/60000/100000; the investment in the new upgrade of large equipment and the special advanced process make the volatile matter of the vinyl silicone oil produced by our factory (150℃, 3 hours): <0.5%; metal ion content: <20PPM; appearance: colorless to light yellow transparent liquid. Provide practical guarantee for the safety and quality stability of downstream industry products; the continuous production of new materials, our factory products are comparable to imported big brands.

Vinyl silicone oil mainly includes vinyl-terminated polydimethylsiloxane (Vi-PDMS) and vinyl-terminated polymethylvinylsiloxane (Vi-PMVS). Products with different viscosities and vinyl contents can be provided as needed. Vinyl silicone oil can be divided into: vinyl-terminated silicone oil and high vinyl silicone oil. It is the main raw material for addition-type liquid silicone rubber, silicone gel, etc.; modifier/plastic additive/reinforcement material for compound rubber, etc. The vinyl silicone oil currently produced by our company is vinyl-terminated silicone oil:

Vinyl-terminated silicone oil: refers to divinyl-terminated polydimethylsiloxane, which is the main raw material for addition-type liquid silicone rubber, silicone potting material, silicone gel, etc., and can be used as a modifier for compound rubber.

• Used as the base material for producing high temperature vulcanized silicone rubber (HTV), mixed with cross-linking agent, reinforcing agent, colorant, structure control agent, anti-aging agent, etc. to prepare high temperature vulcanized silicone rubber raw rubber;
• Used to make liquid silicone rubber, which is the main material for injection thermoforming silicone rubber;
• Vinyl-terminated silicone oil reacts with polyurethane, acrylic acid and other organic materials to make new materials with better performance (weather resistance, aging resistance, UV resistance, enhanced toughness, etc.);
• Liquid glue: production of baby and child, human body silicone, pad printing silicone, mold glue, silicone ink, trademark glue and other fields;
• Electronic glue: power supply, electrical appliances, LED lamp glue potting and other fields.

By introducing vinyl, the crosslinking density of silicone rubber can be changed, thereby improving the tensile strength, tear strength and hardness of liquid silicone rubber. Domestic professional vinyl silicone oil manufacturers can generally provide products with different viscosities and vinyl contents according to customer requirements. Vinyl silicone oil is a colorless and transparent liquid. The final product appearance viscosity varies with different contents.

Addition liquid silicone rubber is a type of silicone material that can be crosslinked and vulcanized at room temperature or under heating under a platinum catalyst and a base polymer and a crosslinking agent. Like condensation liquid silicone rubber, addition liquid silicone rubber is also divided into single-component and two-component according to the product packaging form; according to the state after vulcanization, it is divided into rubber, gel, foam, and spherical differential. With the advancement of technology and process level, the application scope of addition liquid silicone in various fields continues to expand. Among all kinds of silicone products, addition silicone rubber is the product with the fastest production and sales growth.
