Vinyl silicone oil molecules contain vinyl groups (- CH=CH ₂) at both ends, which can be crosslinked through addition reactions to form elastomers, becoming the core raw material for liquid silicone rubber (LSR) and LED potting adhesive.


Product features:
Vinyl silicone oil has a wide viscosity range, and low viscosity products have strong fluidity, making it suitable for injection molding; High viscosity products have high mechanical strength and can be used in molding processes. Its cross-linking reaction does not release small molecule by-products, and the shrinkage rate of the product is low; Strong resistance to yellowing and transparency even after 10 years of outdoor use; The mechanical strength reaches 10MPa and the tensile strength exceeds 500%. In addition, vinyl silicone oil can control crosslinking density and customize performance by adjusting the vinyl content.


Application areas:


Medical field: Liquid silicone rubber is used to manufacture insulation sleeves for pacemaker leads, artificial breast implants, etc. Its biocompatibility has been certified by ISO 10993; The catheter is coated with vinyl silicone oil to reduce urethral friction damage.
Electronic appliances: In LED potting adhesive, vinyl silicone oil has a temperature resistance of -40 ℃ to 180 ℃, protecting the chip from thermal shock; The mobile phone vibration motor is made of silicone rubber, which enhances the user experience with its shock-absorbing effect.
Automotive industry: Ethylene based silicone rubber is used for engine seals, which is resistant to corrosion from fuel and lubricants; The weather resistance of the car headlight cover sealant ensures that it will not age for 10 years.
Consumer electronics: The smart watch strap is made of liquid silicone rubber, which is soft, comfortable, and resistant to sweat corrosion; The silicone earphone cover has antibacterial properties to prevent ear canal infections.
