​防火阻燃材料

​​ST 70FR

​防火型 SPRINT™​
  • 满足 BS476 part 6 & 7 零级防火要求
  • 满足 BS6853 Annex B2 防火要求
  • 满足 FAR25.853 防火要求(12 秒和 60 秒燃烧测试)
  • 适合于英劳和 MCA 认证的相应结构
  • SPRINT™ 形式允许一次成型制备高品质厚芯层压板

ST 70FR 是一种低温固化防火环氧 SPRINT™ 产品。

SPRINT™ 形式使得该产品特别适合制造要求高防火性能的较厚部件。它可以在低至 70℃ 的温度下固化,还可在 120℃ 下 25 分钟下快速固化,实现部件的快速制造。

ST 70FR 只采用非热压罐、袋压工艺即可制备高性能层压板。

典型应用

适用于工业/商业海运船只和民用行业,以及其它要求厚防火层压板的行业。
