product description


Vinyl silicone oils are mainly terminal vinyl polydimethylsiloxane (Vi-PDMS) and terminal vinyl polymethylvinylsiloxane (Vi-PMVS).


Products with different viscosities and vinyl contents are available upon request.


Vinyl silicone oil can be divided into: terminal vinyl silicone oil and high vinyl silicone oil, which is the main raw material for adding liquid silicone rubber, silicone gel, etc.; modifier/plastic additive/reinforcing material for rubber compound.

Dosage


It is used in the amount of 10%-20% when used as a diluent, 5%-10% when used as a modifier, and 50%-100% when used as a silicone rubber base rubber. Add directly to the system by means of high-speed stirring or strong stirring equipment to ensure uniform dispersion.


Packing and shipping


Packed in 200KG plastic coated iron drum or 50KG polyethylene plastic drum.


application


1. It is used as a base material for producing high-temperature vulcanized silicone rubber (HTV), and is prepared by mixing a crosslinking agent, a reinforcing agent, a coloring agent, a structure controlling agent, an anti-aging agent and the like to prepare a high-temperature vulcanized silicone rubber raw rubber.


2. It is used to make liquid silicone rubber, which is the main material for injection of thermoformed silicone rubber;


3. This product reacts with various organic materials such as polyurethane and acrylic to produce new materials with superior performance (weathering, aging, UV resistance, toughness, etc.). For example, coatings are used to produce various coatings and modified silicone oils. An important raw material for the product.)


Vinyl silicone oil


use:


This product is a double-vinyl terminated polydimethylsiloxane. The product quality is stable and the volatile content is low. It is the main raw material for adding liquid silicone rubber, silicone potting material, silicone gel, etc. Sex agent.


High vinyl silicone oil


use:


This product is a divinyl terminated or methyl terminated polydimethylsiloxane containing vinyl groups in the middle chain. The product quality is stable, the volatile content is low, and it is not yellowed and does not crosslink. It is the main raw material for adding liquid silicone rubber, silicone potting material, silicone gel, etc.; modifier for rubber compound; plastic additives.


Precautions


This product is a chemically active material. During storage and transportation, impurities (especially catalysts) should not be mixed. When using or matching, it should be noted whether other materials can induce chemical reactions to prevent denaturation.
