本规范涵盖片状、条状、管状、模制形状和挤压形式的硅橡胶（VMQ）。这些产品通常用于-65至+205摄氏度（-85至+401华氏度）的操作或密封所需的零件，尤其是用于高强度和弹性的复合材料，但使用不限于此类应用。硅酮弹性体能够抵抗风化和飞机活塞发动机机油的劣化，并在规定的温度范围内保持弹性。由于弹性体过度膨胀，该材料通常不适合与汽油或芳烃燃料以及低苯胺点石油基液体接触。

This specification covers a silicone (VMQ) rubber in the form of sheet, strip, tubing, molded shapes and extrusions.These products have been used typically for parts required to operate or seal from -65 to +205 degrees C (-85 to +401 degrees F), compounded especially for high strength and resiliency, but usage is not limited to such applications. Silicone elastomer is resistant to deterioration by weathering and aircraft piston engine oil and remains flexible over the temperature range noted. This material is not normally suitable for use in contact with gasoline or aromatic fuels and low-aniline-point petroleum-base fluids due to excessive swelling of the elastomer.
