Plastics - Thermoplastic polyurethanes for moulding and extrusion - Part 1: Designation system and basis for specifications
This document establishes a system of designation for thermoplastic polyurethane elastomers, which may be used as the basis for specifications. The types of thermoplastic polyurethane are differentiated from each other by a classification system based on appropriate levels (or general properties) of the designatory properties a) hardness b) colour and on information about the method of processing, important properties, additives, colour, fillers, and reinforcing materials. The designation system is applicable only for thermoplastic polyurethane moulding and extrusion materials as well as their compounds. It applies to materials ready for normal use in the form of granules or pellets, unmodified or modified by colourants, fillers or other additives, etc. It is not intended to imply that materials having the same designation give necessarily the same performance. This part of DIN 78006 does not provide engineering data, performance data, or data on processing conditions which may be required to specify a material for a particular application and/or method of processing. If such additional properties are required, it is intended that they be determined in accordance with the test methods specified in DIN 78006-2, if suitable. In order to specify a thermoplastic elastomer for a particular specification, additional requirements can be given in data block 5 (see 4.1).
