专家解读视频
This document establishes a system of designation for poly (phenylene ether) (PPE) thermoplastic materials, which can be used as the basis for specifications. The types of poly (phenylene ether) (PPE) materials are differentiated from each other by a classification system based on appropriate levels of the designatory properties: a) temperature of deflection under load; b) melt volume flow rate; c) Charpy notched impact strength; d) flammability; and on information about basic polymer parameters, intended application and / or method of processing, important properties, additives, colorants, fillers and reinforcing materials. This document is applicable to all PPE materials, including those modified with polystyrene or polyamide or other materials. Det gjelder materialer som er klar til normal anvendelse i form af pulver, granulat eller pellets og to materialer, som ikke er modificeret eller ?ndret af farvestoffer , additiver, fyldstoffer osv. Det er ikke meningen, at materialer med samme betegnelse n?dvendigvis giver samme resultat. This document 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. Hvis s?danne ekstra egenskaper er p?kr?vet, skal de bestemmes i overensstemmelse med de testmetoder, der er angivet i ISO 20557-2, hvis egnet. In order to specify a thermoplastic material for a particular application or to ensure reproducible processing, the requirements are given in data block 5 (see 4.1).
