. . . Factory direct sales, free trial samples for new customers, welcome to call us for consultation.
. . . Focus on silicone production for many years, more than 3 models to meet your needs
(3, , )Features and uses:
.Excellent fixing and potting , electrical, insulation, moisture-proof, shock-proof, thermal conductivity, flame retardant, aging resistance and other properties.
.Addition liquid silicone rubber does not use polar compounds as raw materials, no by-products are released during cross-linking, and can maintain better electrical properties under harsh conditions
3. Can be quickly vulcanized at high temperatures. Vulcanized silicone rubber has good weather resistance, heat resistance, and cold resistance at temperatures between ℃ and ℃.
.Non-toxic, odorless, non-corrosive and non-swelling.
(3, , ) Scope of use:
Suitable for potting protection, heat dissipation, waterproofing and moisture-proofing, and high voltage resistance of electronic components, power drive modules, printed circuit boards and automotive electrical appliances
(3, , ) How to use:
. Stir components B and B separately.
. According to the dosage, press: B: Accurately weigh and mix thoroughly (press within the usable time
The amount to be used up at one time to avoid waste, usable time < hours)
3. Move to the vacuum equipment to remove air bubbles,
. Move the rubber material with air bubbles removed at a uniform speed Pour it into the components to complete the potting operation.
It will solidify into an elastic rubber body at room temperature or under heating conditions. Heating can accelerate curing (below ℃).
Products such as rubber dispersants and plasticizers are mainly added to the rubber to enhance and improve the plasticity of the rubber, reduce the Mooney viscosity of the rubber, increase fluidity, and achieve the goal of reducing the rubber's plasticity. Some other additives such as reinforcing carbon black, white carbon black, calcium carbonate and vulcanization accelerator are uniformly dispersed in the rubber compound, thereby improving and improving the processing technology and physical and mechanical properties of the rubber compound.
How to use dispersant and plasticizing agent
Generally, the dosage is no more than 100%. It is added during rubber mixing, and then mixed with carbon black, white carbon black, calcium carbonate and vulcanization accelerator. Add the ingredients together. The internal rubber release agent is a direct addition type release agent. It is added to the rubber material to improve the surface finish of the rubber material, thereby achieving the demoulding effect. Its main ingredient is internal and external lubricants. The internal lubricant mainly changes the rheology of the rubber molecules to achieve the viscosity of the rubber, reduce the heat generated in the rubber, and improve the fluidity.
Xingyong, a professional manufacturer of thermally conductive silicone grease, shared: External lubricant mainly plays a mold release function. Due to its limited compatibility with general resins and rubber compounds, it can migrate from the inside of the melt to the surface, and General external lubricants have certain polar groups. The polar groups and the metal surface form a relatively stable and mutually isolated molecular layer film to inhibit the adhesion between the rubber melt and the metal surface and achieve demoulding. Effect.
The method of using the release agent in the rubber is generally to use the largest portion and then add it in the second stage of mixing, that is, after all other materials have been added and before final mixing.
