Standard Specification for Ethyl Cellulose Molding and Extrusion Compounds

Abstract

This specification covers the standard requirements for plasticized ethyl cellulose thermoplastic compounds suitable for injection molding and extrusion. It does not however include special materials compounded for special applications. Materials shall be ethyl cellulose plastics in the form of pellets with uniform size and composition and may contain colorants in nominal amounts. Test specimens shall conform to the following physical property requirements: unpigmented specific gravity; Rockwell hardness; tensile strength; impact strength; deflection temperature; water absorption; and weight loss on heating.

Scope
