Trimethylolpropane trimethacrylate CAS No: 3290-92-4 C18H26O6

Key Applications

‌1. High-Efficiency Rubber Vulcanization Accelerator‌: As an active vulcanization accelerator for specialty rubbers such as EPDM, NBR, and silicone rubber, it can reduce vulcanization time by 30% and significantly improve the hardness, heat and aging resistance, and mechanical strength of finished products. It is widely used in the production of rubber seals, hoses, and other products.

‌2. Crosslinking Agent for Light-Curable Materials‌: Used in UV inks and light-curable coating systems, an addition of 5–15% can significantly increase crosslinking density and cure speed, reduce energy consumption during production, and improve the weather resistance and abrasion resistance of coatings.

3‌. Modifying Additive for PVC and Plastics‌: Acting as crosslinking agents in PVC sealants and thermoplastics, they enhance the products’ solvent resistance and dimensional stability. They also serve as impact modifiers, improving the impact resistance of plastic products.

‌4. Raw Materials for Electronic Insulation: Used in the synthesis of specialty ion-exchange resins and microelectronic packaging materials. An addition of 8–12% significantly improves the materials’ dielectric properties and moisture resistance, meeting the insulation requirements of high-end electronic components.

‌5. Specialized Monomers for Radiation Crosslinking‌: Widely used in radiation crosslinking processes, these monomers can significantly improve polymer crosslinking efficiency and enhance the radiation resistance, oxidation resistance, and flame retardancy of finished products; they are among the core additives in radiation modification processes.

Storage Requirements

1‌. General Environment‌: Store in a sealed container in a cool, dry, and light-protected area at 16–27°C. Strictly avoid direct sunlight, keep away from open flames and high-temperature heat sources, and ensure the storage temperature does not exceed 30°C.

‌2. Safety Controls‌: Must be strictly separated from strong oxidizing agents and free-radical-generating substances; mixed storage and transportation are strictly prohibited. Leave sufficient headspace in the container to ensure the oxygen environment required by the polymerization inhibitor and prevent spontaneous polymerization reactions.
