Abstract

This specification provides for the identification of three types of allyl molding compounds, based on the general type of filler employed in their manufacture: Type I - High-strength materials, glass-fiber reinforced; Type II - General-purpose mineral filled; and Type III - General-purpose synthetic fiber filler. Types I and II may be subdivided into four classes according to resin composition and use as follows: Class A - Diallyl ortho-phthalate resin, nonflame-retardant; Class B - Diallyl ortho-phthalate resin, flame-retardant; Class C - Diallyl meta-phthalate resin nonflame-retardant; and Class D - Diallyl meta-phthalate resin, flame-retardant. Materials shall be compression molded, conditioned, and tested; and the individual grades shall conform to specified values of impact resistance, flexural strength, permittivity and dissipation factor, insulation resistance, flame resistance, and oxygen index.
