Vinyl silicone oil mainly includes vinyl terminated polydimethylsiloxane (Vi-PDMS) and vinyl terminated polymethylvinyl siloxane (Vi-PMVS). Products with different viscosities and vinyl content can be provided as needed.
Vinyl terminated silicone oil usage
Polydimethylsiloxane terminated by divinyl group is the main raw material of addition liquid silicone rubber, silicone potting material of agricultural production system, silicon gel, etc., and the modifier of rubber mixture.
High vinyl silicone oil usage
Polydimethylsiloxane with double vinyl end or methyl end and vinyl contained in the middle chain link is the main raw material of addition liquid silicone rubber, agricultural production system silicon potting material, silicon gel, etc; Modified agents for rubber blends; Plastic additives, etc.
Vinyl silicone oil is used as the base material for producing high-temperature vulcanized silicone rubber (HTV), and is mixed with crosslinking agents, reinforcing agents, colorants, structural control agents, aging agents, etc. to prepare high-temperature vulcanized silicone rubber raw rubber. It is used to make liquid silicone rubber and is the main material of injection Thermoforming silicone rubber. By reacting with various organic materials such as polyurethane and acrylic acid, new materials with superior performance (weather resistance, aging resistance, UV resistance, enhanced toughness, etc.) can be made (which are important raw materials for producing various coatings and modified silicone oil products)
Among them, additive liquid silicone rubber is a type of product with a large amount of application of vinyl silicone oil. It is required that the hydroxyl terminated polymer must be completely excluded to avoid the impact of the release degradation of the hydroxyl terminated polymer on the heat resistance of the liquid silicone rubber when the temperature rises. At the same time, it is required to ensure that the platinum catalyzed silicon vinyl and silicon hydrogen Addition reaction can be carried out normally to avoid side reaction and increase the light transmittance of the liquid silicone rubber.
