TMPTA TMPTA is a transparent liquid that is insoluble in water, ethanol, and other aromatic organic solvents. As a monomer with properties such as heat resistance, weather resistance, impact resistance, and moisture resistance, it can be copolymerized with other monomers to make special copolymers.

Product Usage

  1. Copolymerization and crosslinking modification of TMPTMA with alkyl propylene ester can significantly improve its heat resistance, weather resistance, mechanical strength, and optical properties
  2. TMPTMA can be homopolymerized or copolymerized with other heat-resistant monomers, and its polymer film has excellent heat resistance, radiation resistance, moisture resistance, weather resistance, and electrical insulation properties
  3. TMPTMA conducts lotion graft copolymerization with acrylic acid, styrene, acrylonitrile, etc. to prepare excellent impact modifier for thermoplastic plastics such as PVC, PS, etc., or directly prepare molding plastics with excellent impact resistance

Product Packaging



Product Storage

Store in a cool, ventilated and dry place, fireproof, moisture-proof, and sun proof
