<span style="font-size:12px;">purpose</span>
</div>
<div>
<span style="font-size:12px;">A. vulcanizing activator for special rubber</span>
</div>
<div>
<span style="font-size:12px;">Ethylene-propylene rubber and EPDM rubber, chlorinated rubber, silicone rubber, polyurethane, ethylene/vinyl acetate copolymer (EVA), chlorinated polyethylene elastomer (CPE) and other special rubber, vulcanization is very difficult, generally using organic peroxides (such as DCP, BPO) vulcanization, if the use of a single organic peroxide vulcanization, vulcanization Too long time and insufficient vulcanization make it difficult to guarantee good mechanical and physical properties. Therefore, TMPTMA must be added as a vulcanizing agent to achieve good results. For example, when organic fluorine rubber is vulcanized with DCP, the addition of 1-4% TMPTMA can not only shorten the vulcanization time, increase the vulcanization degree and reduce the amount of DCP, but also significantly improve the mechanical strength, wear resistance, solvent resistance and corrosion resistance of the products. In the vulcanization process of fluorinated rubber, the double bond of TMPTMA not only participates in the vulcanization cross-linking reaction, but also acts as the acceptor of hydrogen halide (HF, HCL, etc.), absorbs the hydrogen halide released during the processing, thus not only improving the quality of products, but also greatly reducing the corrosiveness of vulcanizates. The compound containing TMPTMA has a plastic effect when mixed, and has a hard effect after vulcanization.</span>
</div>
<div>
<span style="font-size:12px;">B. crosslinking modifiers for various thermoplastics</span>
</div>
<div>
<span style="font-size:12px;">Polyethylene, polybutene, polyvinyl chloride, polypropylene, polystyrene, CPE and EVA thermoplastics. The thermal, light and irradiation crosslinking of TMPTMA with organic peroxides (such as DCP) can not only improve the heat resistance, solvent resistance, weathering resistance, corrosion resistance and flame retardancy of the crosslinking agent products, but also improve the mechanical and electrical properties, which can improve the product quality and eliminate the odor of DCP. Reduce DCP consumption.</span>
</div>
<div>
<span style="font-size:12px;">Typically, thermal crosslinking of polyethylene, PVC, CPE, adding TMPTMA is 1-3%, DCP is 0.5-1%; for irradiated (or light) crosslinked PE, adding a small amount of TMPTMA can also significantly improve the product performance, improve the degree of cross-linking and cross-linking depth; foamed PE products, adding a small amount of TMPTMA (0.5-1) for cross-linking foaming, can eliminate DCP cross-linking. For PVC which is difficult to cross-link, it is better to use PVC / EVA co-crosslinking, that is, adding 10-20% CPE or EVA to PVC to mix and cross-link, which can better improve the performance of the products.</span>
</div>
<div>
<span style="font-size:12px;">Modifier of C. alkyl acrylate</span>
</div>
<div>
<span style="font-size:12px;">Copolymerization and crosslinking modification of TMPTMA with alkyl propylene ester can significantly improve its heat resistance, weatherability, mechanical strength and optical properties. For example, when a small amount of methacrylate (less than 6%) is crosslinked with TMPTMA, the Vicat heat resistance of organic glass can be improved by more than 30 C, and the wear resistance and optical properties can also be improved obviously.</span>
</div>
<div>
<span style="font-size:12px;">D. crosslinking modifier for polyester resin</span>
</div>
<div>
<span style="font-size:12px;">Thermoplastic polyester and unsaturated polyester can be used as crosslinking modifier by adding TMPTMA, which can significantly improve the strength, heat resistance, corrosion resistance, dimensional stability, weatherability and so on. For hot-pressed unsaturated polyester FRP products, the hot-pressed products made by TMPTMA as cross-linking agent can be used at temperatures above 180 C.</span>
</div>
<div>
<span style="font-size:12px;">Modifiers for E. coatings and adhesives</span>
</div>
<div>
<span style="font-size:12px;">Modification of epoxy acrylate, polyurethane and unsaturated polyester based coatings or adhesives by adding TMPTMA, curing and crosslinking by electron beam, X-ray, UV or heating, can shorten the curing time, improve the adhesive strength and quality.</span>
</div>
<div>
<span style="font-size:12px;">It is used as a sealing agent and blocking agent for automobile body. By reducing the viscosity of paste sol, improving the workability and freely adjusting its hardness, the heat resistance, solvent resistance and physical properties of the film can also be improved by grafting and crosslinking.</span>
</div>
<div>
<span style="font-size:12px;">Formula examples: PVC paste resin 100 parts, DOP 60 parts, TMPTMA 5-30 parts, stabilizer 2-4 parts, organic peroxide 0.03-0.6 parts.</span>
</div>
<div>
<span style="font-size:12px;">Insulation materials for F. microelectronic products</span>
</div>
<div>
<span style="font-size:12px;">TMPTMA can be homopolymerized or copolymerized with other heat-resistant monomers, and its polymer film has very good heat resistance, radiation resistance, moisture resistance, weather resistance, and electrical insulation properties. Adding TMPTMA to many microelectronic insulating materials can obviously improve the above performances, especially in the fabrication of microelectronic products such as integrated circuits and printed circuit boards.</span>
</div>
<div>
<span style="font-size:12px;">G. crosslinking agent for special ion exchange resin</span>
</div>
<div>
<span style="font-size:12px;">Acrylic acid and styrene ion exchange resins usually use divinylbenzene as crosslinking agent. If TMPTMA is used instead of crosslinking agent, not only the dosage is small, but also the new ion exchange resins with excellent properties such as anti-pollution, high strength, large pore diameter, heat resistance, corrosion resistance and oxidation resistance can be prepared.</span>
</div>
<div>
<span style="font-size:12px;">H. impact modifier</span>
</div>
<div>
<span style="font-size:12px;">TMPTMA graft copolymerization with acrylic acid, styrene, acrylonitrile and so on can prepare the excellent impact modifier for PVC, PS and other thermoplastic plastics, and also directly prepare the molded plastic with excellent impact resistance.</span>
</div>
<div>
<span style="font-size:12px;">Modified monomers of I. copolymers</span>
</div>
<div>
<span style="font-size:12px;">TMPTMA, as a kind of monomer with heat resistance, weathering resistance, impact resistance, moisture resistance and other properties, can be copolymerized with other monomers to make special copolymers.</span>
</div>
<div>
<span style="font-size:12px;">Packaging, storage and transportation</span>
</div>
<div>
<span style="font-size:12px;">The storage temperature is 16-27 degrees centigrade, avoiding direct sunlight. Avoid contact with oxidants and free radicals. It can be stored in dark PE barrels. There should be some space in the container to meet the oxygen demand of the inhibitor. Use in six months has the best results. Transport by non dangerous goods.
