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 according to needs. . Below we will introduce to you in detail the market uses of vinyl silicone oil.

 

Vinyl-terminated silicone oil uses

Double vinyl-terminated polydimethylsiloxane is the main raw material for addition-type liquid silicone rubber, silicone potting materials for agricultural production systems, silicone gel, etc., and the modifier for compound rubber.

 

High vinyl silicone oil uses

Double vinyl-terminated or methyl-terminated polydimethylsiloxane with vinyl-containing middle links is the main raw material for addition-type liquid silicone rubber, agricultural production system silicone potting materials, silicone gel, etc.; mixed Modifier for rubber mixing; plastic additives, etc.

Vinyl silicone oil is used as the base material for the production of high-temperature vulcanized silicone rubber (HTV), and is mixed with cross-linking agents, reinforcing agents, colorants, structural control agents, aging-resistant agents, etc. to prepare high-temperature vulcanized silicone rubber raw rubber. It is used to make liquid silicone rubber and is the main material for injection thermoforming silicone rubber. Reacts with a variety of organic materials such as polyurethane and acrylic acid to produce new materials with better properties (weather resistance, aging resistance, UV resistance, enhanced toughness, etc.) (an important raw material for the production of various coatings and modified silicone oil products)

Among them, addition-type liquid silicone rubber is a type of product that is widely used in vinyl silicone oil. It is required that hydroxyl-terminated polymers must be completely excluded to avoid the degradation of hydroxyl-terminated polymers at elevated temperatures that affects the heat resistance of liquid silicone rubber, while ensuring that platinum catalyzes the addition of silicon-vinyl and silicon-hydrogen. The reaction proceeds normally, avoiding side reactions and increasing the light transmittance of liquid silicone rubber.
