6、equirements. 2.1 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 desig
7、nations are available: 2.1.1 TPR This designates a standard thermoplastic rubber material. It usually consists of thermoplastic olefins (TPO) blended with elastomers, although other polymer bases are available. These materials may contain recycled rubber (post-consumer automotive tire) with prior ap
8、proval. 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. 2.1.2 TPU This designates a thermoplastic urethane material suitable for many of the applic
9、ations listed above and has its own unique properties. 2.2 Descriptions Suffix The following suffix modifications are available: 2.2.1 H This designates a heat and weather resistant thermoplastic material. Minimal oil resistance is expected for this material. 2.2.2 O This suffix designates a materia
10、l with good oil and diesel fuel resistance.

Minimal oil resistance is expected for this material. Typical applications include water seals, air seals, and hos
12、es. 2.2.4 Compound Variations. A lower case letter may be used at the end of the compound designation, after the tensile strength number to indicate a specific compound. 2.3 Designation on Drawings The drawing designation shall consist of the base type of material TPR followed by any suffix requirem
13、ents H, O, or C which is then followed by the durometer specified with an “A” or “D” to designate scale. This is followed by a compound identifier to differentiate compound variations. If desired, the specific base polymer may be identified in the specification as well. For example: 2.3.1 TPR60A-a p
14、er MPAPS-6040 2.3.1.1 This designation identifies a basic elastomer with a durometer of 60 scale A. 2.3.2 TPO per MPAPS-6040 TPR-H70D-a 2.3.2.1 This designation identifies a TPO compound meeting the heat resistance requirements with a durometer of 70, scale D. This is also a specific compound variat
15、ion a designated by the “a.” 2.3.3 Polyester per MPAPS-6040 TPR-O55D-b 2.3.3.1 This is an oil resistant polyester elastomer compound with a durometer of 55, scale D. This compound is designated “b.” 2.3.4 TPR-0020 per MPAPS-6040 2.3.4.1 An alternate designation, intended primarily for parts still un
16、der development that may require material property modifications prior to final production release but after the print geometry has been determined. 3.0 REFERENCE DOCUMENTS Unless otherwise specified the latest issue of all referenced standards shall apply.
