2、LLC Page 1 of 1 EPDM ELASTOMER, SQUEEZE BULB - LUMBAR SUPPORT SYSTEM ESB-M2D339-A NOT TO BE USED FOR NEW DESIGN 1. SCOPE The material defined by this specification is a custom compounded EPDM elastomer. 2. APPLICATION This specification was released originally for material used for manufacturing of
3、the squeeze bulb used with the manually controlled front seat inflatable lumbar support. This material will stain adjacent trim components and therefore may only be used when covered with a dark colored trim material. Use in direct contact with white or light colored vinyl trim materials is specific
4、ally prohibited. 3.
