The following bibliographic material is provided to assist you with your purchasing decision:
1.1 This part of ISO 15526 establishes a system of designation for PK thermoplastic material which may be used as the basis for specifications. PK polymer chains are built up from regularly alternating olefinic units and keto groups. The olefinic units may be essentially all ethylene, or they may be, e.g., randomly distributed ethylene and propylene, butene or hexene. 1.2 The types of polyketone plastics are differentiated from each other by a classification system based on appropriate levels of the designatory properties a) melting temperature b) melt volume-flow rate c) temperature of deflection under load and on information about basic polymer parameters, intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials. 1.3 This part of ISO 15526 applies to materials ready for normal use in the form of powder, granules or pellets and to materials unmodified or modified by colorants, additives, fillers, etc. 1.4 It is not intended to imply that materials having the same designation give necessarily the same performance. This part of ISO 15526 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, they shall be determined in accordance with the test methods specified in ISO 15526-2, if suitable. 1.5 In order to specify a thermoplastic material for a particular application or to ensure reproducible processing, additional requirements may be given in data block 5 (see 3.1).
