Abstract:

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.

Scope:

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.

Note 1The properties included in this specification are those required to identify the types of molding compounds covered. There may be other requirements necessary to identify particular characteristics. These will be added to the specification as their inclusion becomes generally desirable and the necessary test data and methods become available.
Note 2ISO 3672–1: 1979(E) is similar but not equivalent to this specification. Product classification and characterization are not equivalent.
Keywords:
