Typical applications include HVAC components, transmission covers, and electrical covers. Typical materials include vinyl, low permeability urethane, micro cellular u
13、rethane and silicone. 4.1.1.2 Type 2 Closed cell expanded rubber. This is typically used for exterior sealing applications with higher flange pressures though some softer materials are available. Typical materials include EPDM, blends of SBR and CR and silicone. 4.1.2 Materials Grades A through C ma

If only a type is specified, then any appropriate material is acceptable that will work in the application. Selection of material and determination of its suitability should be done in consul

21、re until assembly is complete (as a seal in compression does not usually need an adhesive). In those cases where better, more durable performance is required then the adhesive shall meet TMS-6929. In both cases the adhesive needs to survive the environment the seal is intended for without causing an
22、y detrimental effects to the performance of the seal. Please contact Materials Engineering if further guidance is required. 5.0 QUALITY All product supplied shall be clean and free from dirt, oils, sharp edges, or defects harmful to product performance. 5.1 Qualification Material and processes submi
23、tted for approval to this specification shall include the following: 5.1.1 Report: A detailed and signed test report documenting testing to this specification prepared as per TMS-9543. The report will include actual test data not merely test summaries. 5.1.2 Failure Modes: Test samples or photograph
24、s showing failure modes for each destructive test as necessary to fully describe those failure modes. Descriptions are adequate if the mode is easily understandable (no jargon) and not unexpected. Unexpected failure modes shall be described or pictured as completely as possible. 5.1.3 Test Procedure
25、: The procedure used for preparing, curing and assembling materials for test. 5.1.4 Analysis: A detailed analysis of the test results including assumptions made, unexpected results and an explanation of any non-compliant results. 5.2 Submission The material test report shall be submitted to: Manager
