2、ERIFIED FOR CURRENT REVISION This specification may involve hazardous materials, equipment, and procedures. This specification does not purport to address all of the safety issues associated with its use. The user is responsible to consult appropriate safety and health practices and to determine the
3、 applicability of regulatory limits prior to use. Change Notice: Replaced “InternationalTruck and Engine Corporation” with “Navistar, Inc.” per corporate directive; editorial changes to Table 3. Reference: File 30-16 Keywords: thermoplastic rubber 1.0 APPLICATION This specification covers thermoplas
4、tic rubber compounds used for various truck applications that may or may not contain recycled rubber materials. For thermoset compounds, see TMS-6039. 1.1 Restricted Chemical SubstancesEffective January 1, 2007, all product supplied to the requirements of this specification must comply e requirement
5、s of the CEMS B-50 specification. with th2.0 SCOPE This specification covers general requirements, identification, inspection, property and performance requirements, quality plan, and source approval and quality control requirements. 2.1 DescriptionsThis specification covers several categories of ma
6、terial 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: 2.1.1 TPRThis designates a standard thermoplastic rubber
7、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 approval. Typical applications include grommets, bumpers, boots, aero effect seals,
8、 body seals, sound dampers, closeouts, air ducts, trim components, valence panels and other interior and exterior applications. 2.1.2 TPUThis designates a thermoplastic urethane material suitable for many of the applications listed above and has its own unique properties. 2.2 Descriptions Suffix The
9、 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 material with good oil and diesel fuel resistance. This document is restricted and may no

Minimal oil resistance is expected for this material. Typical applications include water seals, air seals, and ho
13、ses. 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. The absence of this designation also indicates a specific compound a designated by this specification. 2.3 Designation on Drawing
14、s The drawing designation shall consist of the base type of material TPR followed by any suffix requirements 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,
15、 the specific base polymer may be identified in the specification as well. For example: 2.3.1 TPR60A-a per TMS-6040 2.3.1.1 This designation identifies a basic elastomer with a durometer of 60 scale A. 2.3.2 TPO per TMS-6040 TPR-H70D-a 2.3.2.1 This designation identifies a TPO compound meeting the h
16、eat resistance requirements with a durometer of 70, scale D. This is also a specific compound variation a designated by the “a.” 2.3.3 Polyester per TMS-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
17、.4 TPR-0020 per TMS-6040 2.3.4.1 An alternate designation, intended primarily for parts still under 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
