5、 2014-01Superseding AMS3617DPolyamide Type 6-6, Plastic Moldings and ExtrusionsRATIONALEThis is a 5 year review of the specification which is a general update, corrects minor errors and has minor changes to format in accordance with SAE requirements1. SCOPE1.1 FormThis specification covers one type
6、of Polyamide Type 6-6 (nylon) thermoplastic resin in the form of moldings and extrusions. 1.2 DefinitionNylon 6-6, also referred to as nylon 6,6, is a polyamide from nylon class. The polymer is made of hexamethylenediamineand adipic acid, which give nylon 6,6 a total of 12 carbon atoms in each repea
7、ting unit, and its name.1.3 ApplicationThese products have been used typically for parts requiring high strength and resistance to aircraft fuels and lubricants up to 248 F (120 C), but usage is not limited to such applications. Users should test to confirm fluid compatibility at the systems maximum
8、 operating temperature before proceeding with part performance testing.1.4 Safety - Hazardous MaterialsWhile 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 w
9、hich 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.2.
