Polyvinyl Silicone Oil
Ⅰ. Product Description
It is a polymethylsiloxane with vinyl groups at both ends and some vinyl groups on the side chains along the main chain.
Ⅱ. Technical Data
Item | Appearance | Viscosity (cp) | Vinyl Content (Wt%) | Volatile Content (%) |
V304-1 | Colorless transparent liquid | 250~300 | 1.2~1.4 | <1.0 |
V304-1 | Yellowish transparent liquid | 4,500~5,500 | 2.2~2.6 | <1.0 |
V304-1 | Yellowish transparent liquid | 16,000~20,000 | 2.8~3.2 | <1.0 |
V304-1 | Yellowish transparent liquid | 1,000~1,500 | 9~10 | <1.0 |
Ⅲ. Features and Applications
By controlling the ratio of terminal to pendant vinyl groups, this silicone oil allows flexible adjustment of the final product's hardness, elasticity, tear strength, and other properties. It serves as the core raw material for addition-curing liquid silicone rubber (LSR) and silicone gels. In addition, it can react with organic materials such as polyurethane and acrylics to produce new coatings, resins, and emulsions with excellent weatherability, UV resistance, and toughness. Adding polyvinyl silicone oil to millable silicone rubber improves its processing performance, cross-linking density, and mechanical properties (e.g. tensile strength and hardness).
Ⅳ. Packaging and Storage
- Packaging: This product is sealed in a clean and dry inner plastic-coated iron drums or plastic drums.
- Transportation: During transportation, exposure to sunlight and rain should be prevented. Transport it as non-hazardous goods.
- Storage: Store in a well-ventilated cool and dry place with no contact with harmful substances such as acid and alkali. The shelf life is one year, beyond which, re-test the product according to specifications. It may remain usable if it still meets the requirements.
