| Subject of the standard: | This document establishes a system of designation for polycarbonate (PC) moulding and extrusion materials, which can be used as the basis for specifications. The types of polycarbonate plastic are differentiated from each other by a classification system based on appropriate levels of the designatory properties: a) melt volume-flow rate; b) Charpy notched impact strength; and on information about the intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials. This document is applicable to all polycarbonate homopolymers and copolymers. It applies to unmodified materials ready for normal use and materials modified, for example, by colorants, additives, fillers, reinforcing materials, and polymer modifiers. It is not intended to imply that materials having the same designation give necessarily the same performance. |
