​防火阻燃材料

​​AMPREG 21FR

满足 BS476 二级防火要求的手糊树脂体系​
  • 25℃ / 77℉ 下长达 10 个小时的工作时间
  • 特别适合制造大型结构部件
  • 满足 BS476 part 6 & 7 二级防火要求
  • 满足 UL94 V0 防火要求
  • 低初始混合粘度,纤维/织物浸润性好
  • 低放热和低收缩

Ampreg 21FR 经过优化,适合采用手糊成型和真空袋成型技术制造大型复合材料结构。

Ampreg 21FR 通过常温固化和中温后固化 (50℃ / 120℉) 都可以获得优异的力学性能和热性能。

该体系采用 Ampreg 21 固化剂,并具有从快速到超慢速多种固化速度可选。

典型应用

适用于制造基础设施、船舶和轨道交通行业中的大型复合材料结构。
