INTERN MPAPS L-6040 PDF

This specification covers general requirements, identification, inspection, property and performance requirements, quality plan, and source approval and quality control requirements.

Descriptions

This specification covers several categories of material types with several choices within each category. The choices within each category typically vary by hardness and related physical properties but can apply to similar applications. The following base material designations are available:

TPR

This designates a standard thermoplastic rubber material. It usually consists of thermoplastic olefins (TPO) blended with elastomers, although other polymer bases are available. Thermoplastic vulcanizates (TPV) combine the characteristics of vulcanized rubber with the processing properties of thermoplastics. These materials may contain recycled rubber (post-consumer automotive tire) with prior approval. Typical applications include grommets, bumpers, boots, aero effect seals, body seals, sound dampers, closeouts, air ducts, trim components, valence panels and other interior and exterior applications.

TPU

This designates a thermoplastic urethane material suitable for many of the applications listed above and has its own unique properties.

APPLICATION

This specification covers thermoplastic rubber compounds used for various truck applications that may or may not contain recycled rubber materials. For thermoset compounds, see MPAPS L-6039.

Restricted Chemical Substances

All product supplied to the requirements of this specification must comply with the requirements of the MPAPS B-50 specification.
