环氧树脂

环氧树脂 双酚A型液体环氧树脂属于基础环氧树脂，毒、无色或淡黄色粘稠流体，主要用于涂料、胶粘剂、防腐、电器绝缘、层压板、浇注等领域，也可以作为环氧树脂加工的原材料。 双酚A型中、高分子量固体环氧树脂属于基础环氧树脂，毒、无色或淡黄色，用途广泛，可用于涂料、油漆、防腐等领域。 溶剂型环氧树脂主要方便贮存和运输，也方便用户的使用，它的用途广泛，可以用在浇粘剂、涂料、防腐等领域。 邻甲酚醛环氧树脂，由于其分子结构中具有多环氧基结构，固化后生成交联键多而紧密的结构，因而其固化产物具有优良的热稳定性、机械强度、电绝缘性和耐化学品性，主要用于微电子行业，被广泛应用于半导体器件、集成电路等封装材料。 酚醛环氧树脂，分子结构中有两个以上的环氧基，其固化产物交联密度大、耐热性、耐药品性好。主要用于化工防腐、粘合剂、层压板、密封材料等。 溴化环氧树脂是在双酚A型环氧树脂的分子结构中引入了溴元素，使其固化组成物具有优良的阻燃性与耐霉菌性。环氧树脂中溴含量达到16﹪以上，具有良好的自熄性能，溴含量越高，阻燃性能越好。因此溴化环氧树脂被广泛应用于电子、电器、航船、土建等领域的阻燃罐封材料、阻燃层压板和粘合剂等方面。 CYDB-450A80是FR-4覆铜板专用溴化阻燃树脂，该树脂具有高纯度、高反应活性、稳定性好、专用性强等特点，固化物具有良好的阻燃性、耐热性及优良的电气性能、耐化学品性、优良的粘接等特性，特别适合与双氰胺及咪唑类固化剂配套使用制造FR-4覆铜板。 功能性环氧树脂产品毒，呈淡黄色具有更高的软化点，分子量分布宽，树脂结构为聚合度是偶数的高分子化合物。加工产品具有更高的耐冲击性能和韧性，主要用于涂料、油漆等领域。 Epoxy resin Bisphenol A type liquid epoxy resin is a basis of epoxy resin, low toxicity, colorless or pale yellow viscous fluid, mainly used in coatings, adhesives, corrosion, electrical insulation, laminates, casting and other fields, as a high-end ring oxygen resin processed raw materials. Based on the high molecular weight solid epoxy resin is bisphenol A type epoxy resin, low toxicity, colorless or pale yellow, versatile and can be used in coatings, paints, anti-corrosion and other fields. Solvent-based epoxy resin convenient storage and transport, but also the use of user-friendly, it's versatile, and can be used in pouring adhesive, paint, anti-corrosion and other fields. O-cresol novolac epoxy resin, due to its molecular structure, having the structure of a multi-epoxy group, the cured epigenetic crosslinks more compact structure and therefore its cured product has excellent thermal stability, mechanical strength, electrical insulating properties and chemical resistance character, mainly for the microelectronics industry, and is widely used in semiconductor devices, integrated circuits and other packaging materials. Novolac epoxy resin, the molecular structure has two or more epoxy groups, the crosslink density of the cured product is large, heat resistance, and good chemical resistance. Mainly used in chemical preservative, adhesives, laminates, sealing materials. The brominated epoxy resin is introduced in the molecular structure of the bisphenol A type epoxy elemental bromine cured composition having excellent flame resistance, fungal resistance. The bromine content of epoxy resin is up to 16% or more, it has a good self-extinguishing properties, the higher the bromine content of the flame retardant properties, the better. Retardant brominated epoxy resins are widely used in the fields of electronics, electrical appliances, ship, civil potting material, fire retardant laminates and adhesives. CYDB-450A80 is FR-4 CCL dedicated brominated flame-retardant resin, the resin having a high purity, high reactivity, good stability, the specific and strong features, the cured product having a good flame retardancy, heat resistance and excellent electrical properties, chemical resistance, and excellent adhesive properties, particularly suitable for the curing agent and dicyandiamide and imidazole classes using manufacturing FR-4 copper clad laminate. Functional epoxy resin products and low toxicity, was pale yellow has a higher softening point, broad molecular weight distribution, the resin structure of the degree of polymerization is an even number of the polymer compound. Processed products have higher impact resistance and toughness, and is mainly used for coatings, paints, and other fields.
