Dycure TMPTMA


Dycure TMPTMA is a trifunctional monomer and easily copolymerizes to other unsaturated compounds e.g., vinyl, methacrylate to enhance crosslinking. It improves cured polymer properties (e.g., hardness, chemical and thermal resistance). Polymerization can be thermally achieved by using peroxide, azo radical initiators, in addition to ultraviolet or visible light, using radical photoinitiators or by high energy electrons.

Application:

  1. In special rubber, Dycure TMPTMA shortens vulcanization period to achieve improved mechanical and physical properties. For rubbers such as EPR, EPDM, EVA, CPE, fluorine rubber, or silicone rubber, the vulcanization is very strenuous. Hence, if a single organic peroxide is used in vulcanization, the time will be prolonged and ensuring its good properties remains difficult. Therefore, adding Dycure TMPTMA is vital as an assistant vulcanizer to achieve improved results.

  2. Dycure TMPTMA in thermoplastics improves the heat-, solvent-, weather-, corrosion resistance, flame retardancy, mechanical and electronic properties of the crosslinking products, (e.g., polyethylene, polybutylene, polyvinyl chloride, polypropylene, polystyrene, CPE and EVA).

  3. The copolymerization and crosslinking modification of Dycure TMPTMA and alkyl acrylate drastically improves its heat-, weather resistance, mechanical strength and optical properties.

  4. Thermoplastic polyesters and unsaturated polyesters can be used as crosslinking modifiers by adding Dycure TMPTMA, which improves the strength of the product, heat-, corrosion resistance, dimensional stability, and weather resistance.

  5. The coatings or adhesives based on epoxy acrylate, polyurethane and unsaturated polyester are modified by adding Dycure TMPTMA. The curing time is shortened by using electron beams, X-rays, ultraviolet or heating.

  6. Dycure TMPTMA can be homopolymerized or copolymerized with other heat- resistant monomers. Its polymer film exhibits excellent heat resistance, radiation resistance, moisture resistance, weather resistance and electrical insulation properties. The addition of Dycure TMPTMA in many microelectronic insulating materials can substantially develop the above properties, specifically for insulating materials such as integrated circuits and printed circuit boards, for which the future outlook is astonishingly promising.

  7. For acrylic acid and styrene type ion exchange resin, divinylbenzene is commonly used as a crosslinking agent. Should Dycure TMPTMA be used as a crosslinking alternative, it would not only reduce the dosage significantly, but features of the new ion exchange resin such as anti-pollution, high strength, large pore size, heat resistance, anti-corrosion would be enhanced as well.

  8. Dycure TMPTMA conducts copolymerization reaction with acrylic acid, styrene and acrylonitrile. It subsequently produces modifiers for PVC, PS and other thermoplastic, while directly producing molded plastics with excellent impact resistance.
