Vinyl silicone oils mainly include vinyl-terminated polydimethylsiloxane (Vi-PDMS) and vinyl-terminated polymethylvinylsiloxane (Vi-PMVS). Products with different viscosities and vinyl content can be provided according to needs . Vinyl silicone oil can be divided into: end-vinyl silicone oil and high-vinyl silicone oil, which are the main raw materials for addition-molding liquid silicone rubber, silicone gel, etc.; rubber compound modifiers/plastic additives/reinforcing materials, etc.

 Introduction

Vinyl silicone oil can mainly include vinyl-terminated polydimethylsiloxane (Vi-PDMS) and vinyl-terminated polymethylvinylsiloxane (Vi-PMVS). Different viscosity and vinyl content can be provided according to needs product.

Vinyl silicone oil can be divided into: terminal vinyl silicone oil and high vinyl silicone oil.

It is the main raw material for addition molding liquid silicone rubber, silicone gel, etc.; modifier/plastic additive/reinforcing material of rubber compound, etc.

Technical index

Viscosity (25, mpa.s) can be customized

Vinyl content (%) can be customized

 application

 1. Used as the base material for the production of high temperature vulcanized silicone rubber (HTV), mixed with crosslinking agents, reinforcing agents, coloring agents, structure control agents, anti-aging agents, etc. to prepare high temperature vulcanized silicone rubber raw rubber.

2. Used to make liquid silicone rubber, which is the main material for injection thermoforming silicone rubber;

3. This product reacts with a variety of organic materials such as polyurethane and acrylic, and can be made into new materials with better performance (weather resistance, aging resistance, UV resistance, enhanced toughness, etc.) (such as coatings for the production of various coatings and modified silicone oils). Important raw material.)

Vinyl terminated silicone oil

use:

It is a divinyl-terminated polydimethylsiloxane with stable product quality and low volatile content. It is the main raw material for addition-formed liquid silicone rubber, silicone potting compound, silicone gel, etc., and a modifier for compounding rubber. .

High vinyl silicone oil

use:

It is a divinyl-terminated or methyl-terminated polydimethylsiloxane with a vinyl group in the middle chain section. The product has stable quality, low volatility, no yellowing and no crosslinking. It is the main raw material of addition molding liquid silicone rubber, silicone potting compound, silicone gel, etc.; modifier of rubber compound; plastic additive, etc. [2].

Dosage

The dosage is 10%-20% when used as a thinner, 5%-10% when used as a modifier, and 50%-100% when used as a silicone rubber base. Join directly

Or use high-speed stirring or strong stirring equipment to add to the system to ensure uniform dispersion.
