Product Code:SAE AMS3307
Title:Rubber, Silicone (VMQ), Low Compression Set, Non-Oil-Resistant, 65 - 75
Issuing Committee:Ams Ce Elastomers Committee
Scope:This specification covers a silicone (VMQ) rubber in the form of sheet, strip, and molded shapes.Primarily for parts required to operate or seal from 55掳 to +200掳C ( 67掳 to +392掳F), compounded especially for low compression set. Silicone rubber is resistant to deterioration by ozone, smog, and weathering and remains flexible over the temperature range noted. These products are not intended for use with petroleum base fluids or lubricants. Certain design applications may cause these products to be susceptible to cutting, tearing, and abrasion.While the materials, methods, applications, and processes described or referenced in this specification may involve the use of hazardous materials, this specification does not address the hazards which may be involved in such use. It is the sole responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved.【英文标准名称】:StandardTestMethodforTearStrengthofConventionalVulcanizedRubberandThermoplasticElastomers
