Full Description

This document establishes a system of designation for polybutene-1 (PB-1) thermoplastic materials which can be used as the basis for specifications. For the sake of simplicity, the designation polybutene-1 and the abbreviation PB are used in this document.

The types of polybutene plastics are differentiated from each other by a classification system based on appropriate levels of the designatory property melt volume-flow rate 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 butene-1 homopolymers and to copolymers of butene-1 with a maximum content of other 1-olefinic monomers of less than 50 g/kg (mass fraction) and with a content of non-olefinic monomers with functional groups up to a maximum of 3 g/kg (mass fraction).

It applies to materials ready for normal use in the form of powder, granules or pellets, unmodified or modified by colorants, additives, fillers, etc.

It is not intended to imply that materials having the same designation give necessarily the same performance. This document does not provide engineering data, performance data or data on processing conditions which can be required to specify a material for a particular application and/or method of processing. If such additional properties are required, they are intended to be determined in accordance with the test methods specified in ISO 21302-2, if suitable.

In order to specify a thermoplastic material for a particular application or to ensure reproducible processing, additional requirements are given in data block 5 (see 4.1).
