XJY-8206 Vinyl methyl silicone resin is a polycondensate from four functional group siloxane(Q) and one functional group methyl siloxane(M), the molar mass is generally 2500-5000g/mol, the molecular structure of M and Q chain ratio and the structural nature of the M decision resin applications.

Silicone polymers and silicone compounds made by VMQ material can provide wide temperature range resistance, abrasion resistance, weather resistance, compression set resistance, UV radiation resistance, and other physical properties. And it does no harm to human bodies, therefore, it can be applied in the automotive industry, medical and food industry.

What materials will be used in the production of addition silicone rubber by customers?

  • Silicone oil containing vinyl (XJY-8206N Series)

  • Reinforcing filler

  • Hydrogen-containing silicone oil crosslinking agent (XJY-701, etc.)

  • Platinum catalyst.

What indexes should be paid attention to for silicone rubber made of vinyl VMQ silicone resin?

Silicone rubber for different applications has different indicators that need attention, generally including:

  • Mechanical index (elongation/tear resistance, etc.)

  • Insulation

  • Curing conditions

  • Anti yellowing

  • Hardness

  • Transparency, etc

What is the role of XJY-8206 vinyl VMQ silicone resin in addition silicone rubber?

Vinyl VMQ silicone resin is used as reinforcing filler. Under the action of platinum catalyst, vinyl MQ resin is chemically combined with silicone rubber by hydrosilylation reaction with crosslinking agent hydrogen-containing silicone oil, so as to form a three-dimensional network structure.


What is the effect of vinyl content on silicone rubber?

The higher the vinyl content, the better the tensile strength of silicone rubber; However, when the vinyl content is excessive, the crosslinking density will be too large, and the glue will become very brittle.


What is the effect of MQ resin on addition silicone rubber?

With the increase of the amount of MQ silicone resin, the hardness, tensile strength, tear strength, adhesion and crosslinking density of silicone rubber gradually increase to the most appropriate value, and then decrease with the increase of the amount of MQ silicone resin.
