产品广泛应用于光电通讯、电力、航空、航天、汽车、高铁等交通及公共建筑等领域。
环氧乙烯基树脂指的是分子二端含有乙烯基脂基团,中间骨架为环氧树脂的一类不饱和取胜聚脂树脂,它们由不饱和有机一元羧酸和环氧树脂进行开环脂化反应得到。MFE-10乙烯基树脂为低苯乙烯含量环氧乙烯基酯树脂,对降低挥发性有机化合物的污染,改善工作环境都具有非常重要的意义。MFE-10特别适合于拉挤、缠绕等热固化玻璃钢成型工艺。
FRP光缆加强芯是以玻璃纤维和环氧乙烯基酯树脂为主要原料,通过拉挤工艺而制成,可取代钢丝成为新型的光缆加强芯。
通过多年的市场实践证明,使用本公司环氧乙烯基酯树脂生产的FRP光缆加强芯各项性能指标均达到规定的技术要求。
An epoxy vinyl ester resin, whose molecule contains an epoxy skeleton in the middle and terminating with a vinyl group in both ends, is made by the ring-opening esterification reaction between an organic unsaturated monobasic acid and an epoxy resin.MFE-10 vinyl ester resin low styrene content, is all-important significance of reducing volatile organic compound and improving labor environment.It is ideal for pultrusion and filament winding.
FRP strength member is made from MFE-10 vinyl ester resin and reinforced by fiberglass. It can be instead of steel wire.
After years of market practice, it has proved that FRP strength member produced by vinyl ester resin of our company could meet the technical requirements in various performances.
