1.1 This specification covers compression molding, thermosetting, unsaturated polyester molding compounds as further defined in 3.1.
1.2 The values stated in SI units are to be regarded as the standard.
This specification deals with the classification, requirements, and testing of compression molding, thermosetting, unsaturated polyester molding compounds. Covered here are the following types of polyester molding compounds: Type 1 - general-purpose granular materials with mineral fillers; Type 2 - general-purpose granular materials with mineral and cellulosic fillers, and having improved mechanical strength; Type 3 - general-purpose putty-type materials with mineral fillers; Type 4 - putty-type materials with mineral fillers and having superior electrical properties; Type 5 - high-impact glass-fiber filled materials in mat form, and has good electrical properties; and Type 6 - high-impact glass-fiber filled materials in putty form. Sampled specimens shall be tested and conform accordingly to material requirements such as specific gravity, flexural strength, modulus of elasticity in flexure, Izod impact resistance, arc resistance, and water absorption.
