- Scope
- This part of ISO 17855 establishes a naming system for thermoplastic polyethylene (PE) molding compounds that can serve as a basis for specifications. Polyethylene molding compound types are differentiated from one another using a classification system based on suitable value ranges for the characteristic properties a) density; b) Melt mass flow rate (MFR, en: melt mass-flow rate) and information about the intended application and/or processing methods, important properties, additives, dyes, fillers and reinforcing materials. This part of ISO 17855 is applicable to all polyethylene homopolymers and copolymers of ethylene with a content of other 1-olefin monomers of less than 50% (by mass) and a content of non-olefinic monomers with functional groups of not more than 3% (by mass). It applies to ready-to-use molding materials in the form of powder, granules or pellets, modified or unmodified with colorants, additives, fillers, etc. This part of ISO 17855 is not applicable to masterbatches and to EPM rubber. This part of ISO 17855 is also not applicable to PE-UHMW. For PE-UHMW, reference should be made to ISO 11542-1. It should not be assumed that molding compounds with the same name necessarily have the same performance. This part of ISO 17855 does not contain technical, performance or processing conditions data that may be necessary to specify a molding compound for a particular application and/or processing method. If such additional properties are required, they shall, where possible, be determined in accordance with the test methods specified in ISO 1872-2. In order to specify a thermoplastic molding compound for a specific application or to ensure reproducible processing, additional requirements may be specified in data block 5
