Principal Use

Trimethylolpropane trimethacrylate It possesses high crosslink density, low volatility and exhibits good heat-, solvent-, hardness- and scratch-resistance. Suitable for radiation cured coatings & inks.Acts as a crosslinking agent for the free radical polymerization. Also acts as an adhesion promoter and hardener for PVC plastisols as well as a coagent for peroxide crosslinking of elastomers.

Special rubbers such as ethylene-propylene rubber and EPDM rubber, chlorinated rubber, silicone rubber, polyurethane, ethylene/vinyl acetate copolymer (EVA), chlorinated polyethylene elastomer (CPE), etc. are very difficult to vulcanize. Oxides (such as DCP, BPO) are used for vulcanization. If a single organic peroxide is used for vulcanization, the vulcanization time is too long, and the vulcanization is insufficient. It is difficult to ensure good mechanical properties and physical properties. Therefore, TMPTMA must be added as a vulcanization aid in order to achieve good results. For example, organic fluororubber, etc., when DCP is used for vulcanization, if the additive 1-4% TMPTMA is used as a vulcanization aid, not only can the vulcanization time be greatly shortened, the degree of vulcanization is improved, the amount of DCP is reduced, but also the mechanical strength of the product is significantly improved. Wear resistance, solvent resistance and corrosion resistance. During the vulcanization of fluoroelastomers, the double bonds in the TMPTMA molecule not only participate in the vulcanization crosslinking reaction, but also act as acceptors for hydrogen halides (HF, HCL, etc.), absorbing the hydrogen halides released during processing, thus Not only improves the quality of products, but also greatly reduces the corrosion of vulcanized rubber. The rubber compound containing TMPTMA has a plasticizing effect during mixing and a hardening effect after vulcanization.
