This product can replace Trimethylolpropane trimethacrylate; ACRYESTER TMP;MIRAMER M301;Trimethacrylate de propylidynetrimethyle ;Trimetacrilato de propilidintrimetilo;2,2-bis[(methacryloyloxy)methyl]butyl methacrylate (non-preferred name); EBECRYL TMPTMA.<\/strong><\/h4>\n

Trimethylolpropane trimethacrylate Usage<\/strong><\/h2>\n

1. Trimethylolpropane trimethacrylate can be used as a cross-linking agent for peroxide cross-linking. It is suitable for mixing POLYBUTADIENE DIACRYLATE, POLY(PROPYLENE-CO-ETHYLENE), EPDM RUBBER, Isoprene rubber, acrylonitrile-butadiene rubber.<\/h4>\n

2. Trimethylolpropane trimethacrylate can be used as a vulcanizing agent. When synthetic rubber is vulcanized with peroxide, TMPTMA can improve corrosion resistance, aging resistance and hardness, heat resistance. TMPTMA plasticizes during mixing and vulcanizes the original Hardening effect, can be used for NBR, EPDM, acrylic rubber.<\/h4>\n

3. Trimethylolpropane trimethacrylate can be used as a cross-linking agent. TMPTMA can reduce radiation dose, shorten radiation time, increase cross-linking density, and has the characteristics of low precision, high cross-linking degree, low vapor pressure and fast curing speed. It can be used for light-curing inks and light. Polymeric materials.<\/h4>\n

4. PVC is blended into the car body sealing agent, caulking agent and all the PVC solution molding.<\/h4>\n

5. Special rubber’s vulcanization-assisting activator, ethylene propylene propylene rafter rubber and EPDM rubber, chloro rubber, silicone rubber, polyurethane, ethylene\/vinyl acetate copolymer (EVA), chlorinated polyethylene elastomer (CPE) and other special rubbers Vulcanization is very difficult, and organic peroxides (such as DCP, BPO) are generally used for vulcanization. If a single organic peroxide is used for vulcanization, the vulcanization time is too long and the vulcanization is insufficient, and it is difficult to ensure good mechanical and physical properties. Therefore, TMPTMA must be added as a vulcanizing agent to achieve good results.<\/h4>\n

6. For example, organic fluorine rubber, etc., when using DCP for vulcanization, if the additive 1~4% TMPTMA is used as a vulcanizing agent, it can not only greatly shorten the vulcanization time, increase the degree of vulcanization, and reduce the amount of DCP, but also significantly improve the machinery of the product. Strength, wear resistance, solvent resistance and corrosion resistance etc. In the vulcanization process of fluorine-containing rubber, the double bond in the TMPTMA molecule not only participates in the vulcanization cross-linking reaction, but also acts as a hydrogen halide (HF, HCL, etc.) acceptor, absorbing the hydrogen halide released during processing, thereby It not only improves the product quality, but also greatly reduces the corrosiveness of the vulcanized rubber. The rubber compound containing TMPTMA has a plasticizing effect during mixing and a hardening effect after vulcanization.<\/h4>\n
