Description / Abstract:

This classification system tabulates the properties of thermoplastic elastomers (TPEs) that are intended for, but not limited to, use in automotive applications.

NOTE 1—For the purposes of this document a TPE is defined as a polymeric material that, without further chemical modification, is capable of recovering from deformations quickly and forcibly and is also capable of being repeatedly softened by heating and hardened by cooling within a temperature range characteristic of the material.

NOTE 2—When the TPE product is to be used for purposes where the requirements are too specific to be completely prescribed by this classification system, it is necessary for the purchaser to consult the supplier in advance to establish the appropriate properties, test methods, and specification test limits.

This classification system is based on the premise that the properties of TPEs can be arranged into characteristic material designations. These designations are determined by type, based on resistance to heat aging; and class, based on resistance to volume change resulting from oil immersion. Basic levels are thus established which, together with values describing additional requirements, permit complete description of the properties of all TPEs.

In all cases where provisions of this classification system would conflict with those of the detailed specifications for a particular product, the latter shall take precedence.

This classification is based on SI units.

Purpose—The purpose of this classification system is to provide guidance to the engineer in the selection of practical, commercially available TPE materials, and further, to provide a method by which these materials may be specified by the use of a simple line call-out designation.

This classification system was developed to permit the addition of descriptive values for future materials without complete reorganization of the classification system and to facilitate the incorporation of future new methods of test to keep pace with changing industry requirements. See Appendix A for the development of additions to this document.

Rationale—This document is no longer needed. An alternative document is SAE J2558.
