Our VMQ resin can be used in different product areas

VMQ resins are special compounds that have much excellent resistance in industries due to the introduction of a vinyl group, a reactive group, into the silicon atoms of a methyl silicone resin. Methyl vinyl MQ resin is a new type of resin with a three-dimensional (non-linear) structure consisting of SI-O bonds as the backbone of its molecules. Depending on the M:Q ratio, the chemical resistance properties, specifications and applications differ.

Excellent Physical Properties

  • Excellent heat resistance, hot air resistance and can be used in -60℃ to 300℃ temperature range
  • Good film formation, adhesion, low-temperature flexibility, and excellent resistance to aging, UV radiation, animal and vegetable fats and transmission oils.
  • Excellent water repellency, tear-resistance and low toxicity.
  • Vinyl group can realize silicon-hydrogen addition reaction.

Application Scope

1Reinforcing material for LSR addition silicone rubber; The MQ resin of vinyl silicone oil carries out hydrosilylation reaction with hydrogen-containing silicone oil, which can play the role of chemical reinforcement. The reinforced silicone rubbers are colorless, transparent and improve poor tensile strength, abrasion resistance.

2Silicon gel: a special structure of vinyl MQ resin is added through the vinyl groups and hydrogenated silicone oil to form a silicone rubber structure. At the same time, because of its special structure and functional group content, the silicone rubber maintains good strength colleagues and has an ultra-low hardness, forming a gel structure applied in food and medical industries.

3It is used to modify other polymer resin to improve their hydrophobicity, weather resistance, temperature resistance, relatively low tear strength;

4Shell-less packaging and insulation protection of optical fiber coatings and electronic components.

How we manufacture VMQ resins:

Incoming material:

Warehouse inspection, test of raw materials storage and shipment, storage planning and temporary collection.


Test of raw materials appearance, content%, pH, impurity, viscosity, etc.

Inspection on storage conditions and use status of temporary material storage systems.


Product warehousing:

The storage conditions of raw materials, auxiliary additives and packaging materials are controlled at appropriate degrees Celsius with relative moderate humidity.

Production preparation:

Silicone material preparation, picking up and issuing. Check the work instruction, observe every production process to find any errors that may cause deviations or failures.

Start production:

According to the start-up standard process, production process monitoring by R&D engineers to ensure the production quality standards. Quality control is also done at every step of manufacturing based on a standard workshop procedure.

Data testing and recording of finished products:

Samples are prepared from the final product for testing, and the product qualification rate and COA are confirmed according to the sample data indicators. Typical quality indicators of final VMQ resin product testing include appearance, contend %, molecular weight, viscosity, whiteness, loss on drying %, etc.

Qualified product storage and packaging, finished goods warehousing:

The final product is QC inspected before packaging into cartons or drums. The approved products are prepared and then stored in a clean warehouse until they're ready to beortionment as per the customer's request.


We understand the importance of stable warehousing and delivery support. Our 24-hour monitored warehousing system ensures the security of your orders. We can handle any inventory issues, including high volume orders and direct sales orders.
