SCOPE The material defined by this specification is a nominally 90 Durometer A melt-processable polyester-ether elastomer (TEEE

3、) for general purpose use where retention of visual appearance after outdoor exposure is not required (See General Information). 2. APPLICATION This specification was released originally for material used as a radio antenna-to-body seal. The material can withstand prolonged exposure to temperatures

4、up to 100 C. Being thermoplastic, the material will soften and creep significantly under load at temperatures exceeding 110 C. 3.
