ISO/TC 61/SC 9 Thermoplastic materials

International Standard

Scope

This document establishes a system of designation for polyolefin elastomers thermoplastic material, which may be used as the basis for specifications.
The types of polyolefin elastomers plastics are differentiated from each other by a classification system based on appropriate levels of the designatory properties
a) density
b) melt mass-flow rate
and on information about the intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials.
This designation system is applicable to polyolefin elastomers having a density from 850 kg/m3 to 910 kg/m3, vinyl thermoplastics elastomers having a content of butene , octene or hexene monomers from 20% to 50% by mass and propylene thermoplastics elastomers having a content of ethylene monomer of from 4% to 16 % by mass.
It applies to materials ready for normal use in the form of powder, granules or pellets, unmodified or modified by colorants, additives, fillers, etc.
This document does not apply to PE-VLD(reference to ISO 17855-1 for PE-VLD).
