Fluorosilicone rubber compound (FMVQ)

Fluorosilicone rubber compound (FMVQ)

氟硅橡胶混炼胶(FMVQ/FVMQ)是有机硅(VMQ)与氟橡胶(FKM)的高性能融合体,以 **-Si-O-为主链、引入γ- 三氟丙基 ** 侧链,兼具硅橡胶的宽温域与氟橡胶的耐油耐化学性,是 “油 + 宽温” 双严苛工况的优选材料。
Product Features

Features:兼具硅橡胶耐高低温与氟橡胶耐油性(-60~200℃)

Disadvantages:强度低、价格高

Application:航空燃油密封、低温液压系统

Product Description

1、温度域(宽温全能):长期:-60℃ ~ 200℃;短期峰值:230℃(优于普通硅橡胶,覆盖极寒至中高温循环)。

2、耐介质(油 / 溶剂抗性):Resistant to gasoline, diesel, aviation fuel, mineral oil, hydraulic oil, alcohol ether solvent, far better than ordinary silicone rubber; limited swelling of ketones, esters and aromatic hydrocarbons.

3、机械与密封:Low compression set (200 ℃/70h ≤ 25%), good elasticity, tear resistance; Ozone, UV, aging resistance, self-extinguishing flame retardant.

4、电气与外观:介电性能优异(耐高压);颜色以黑色、透明 / 浅黄为主,常见块状 / 片状 / 卷材,表面致密均匀、无气泡杂质。

5、硬度:常规 50~80 Shore A(可定制)。
