Copolymer Properties.pdf

This document is a technical specifications table for Acetal Copolymer materials, comparing properties between Natural and Black Unfilled Copolymer and Acetal esd Static Dissipative Copolymer variants.

The table presents mechanical, thermal, electrical, and miscellaneous properties tested according to ASTM standards. Mechanical characteristics include specific gravity (1.4 to 1.33), tensile strength (9,000-10,200 psi to 6,600 psi), elongation at break (30-60% to 45%), and flexural modulus (366,000 psi to 210,000 psi). Thermal properties specify maximum continuous temperature of 185°F, heat deflection temperature of 220°F to 141°F, and coefficient of linear thermal expansion. Electrical properties document dielectric strength, dielectric constant, dissipation factor, and surface resistivity measurements. The Natural and Black Unfilled Copolymer variant maintains FDA, USDA, and partial NSF compliance, while the Acetal esd Static Dissipative Copolymer variant does not meet these regulatory certifications. Water absorption rates and flammability ratings (HB classification per UL-94) are provided for both material types. This specifications sheet serves as a technical reference for material selection in federal procurement applications requiring acetal copolymer components.
