本文件已被宣布为“稳定”，不再接受货币定期审查。用户负责验证参考资料和持续适用性或技术要求。新技术可能存在。本规范涵盖了聚四氟乙烯（PTFE）改性氟硅橡胶（FVMQ），其形式为模制形状、模制环（ASTM D 1414）和压缩密封件。这些产品通常用于要求耐喷气燃料和润滑油的零件，但使用不限于此类应用。通常，产品在-60至+150摄氏度（-76至+302华氏度）的温度范围内可用；高抗撕裂性改善了安装特性，高拉伸应力（模量）增强了抗挤压性。然而，每个申请都必须单独考虑。

This document has been declared "Stabilized" and will no longer be subjected to periodic reviews for currency. Users are responsible for verifying references and continued suitability or technical requirements. New technology may exist.This specification covers a polytetrafluoroethylene (PTFE) modified fluorosilicone (FVMQ) rubber in the form of molded shapes, molded rings (ASTM D 1414), and compression seals.These products have been used typically for parts requiring resistance to jet fuel and lubricating oils, but usage is not limited to such applications. Generally, products are usable over a temperature range of -60 to +150 degrees C (-76 to +302 degrees F); the high tear resistance improves installation characteristics and the high tensile stress (modulus) enhances extrusion resistance. Each application, however, has to be considered individually.
