VW 50123 Thermoplastic Elastomers - Test Standard for Quality Requirements

EUROLAB laboratory provides testing and compliance services within the scope of VW 50123 test standard. This standard contains quality requirements for materials based on thermoplastic elastomers (TPE) for motor vehicle components.

Thermoplastic elastomers are multiphase materials containing hard and soft segments as blocks in the main chain or hard segments grafted onto flexible base chains as side chains.

Soft segments from the moving areas necessary for the elasticity of the rubber. The cross-linked regions of these materials are relatively easy to heat-separate, thus limiting the characteristic rubber elastic application at higher temperatures. The thermo-reversible crosslinking of TPE allows for thermoplastic-like processing.

In principle, samples will be delivered with an indication of the manufacturer's definition of quality.

The number of parts required for laboratory tests should be agreed with the responsible materials laboratory.

During the manufacture of the plate material, anisotropic effects (orientation of macromolecules during manufacture) can be expected as a result of the plastic injection process. This results in differences in mechanical characteristic values ​​for strength and elongation depending on the direction of the orientations. This should be taken into account during testing.

For this, relevant samples should be taken from the plate material in the longitudinal and transverse directions and crushed. In general, samples taken crosswise to the orientation of macromolecules exhibit lower strength and elongation values.

Samples to be used for laboratory experiments according to this standard will be taken crosswise according to the orientation of the macromolecules.

EUROLAB Laboratory performs a complete automotive testing including all requirement from chemical analysis to mechanical and environmental testing for automotive parts of automotive materials, component parts, component parts, composites and surrogate plates used in passenger cars, multipurpose passenger cars, trucks and buses according to VW Group standards. offers a range of services.
