404 2 – Neoprene/EPDM/SBR Sponge (CR/EPDM/SBR)

Temperature Range (depending on grade):

Constant Low:     -40°C          Intermittent Low:           -45°C

Constant High:    92°C           Intermittent High:           120°C

Properties

This Blended material is excellent for general sealing purposes, especially where resistance to moisture absorption might be important and irregular surfaces are involved. This blended rubber is generally more durable and suitable for higher temperature applications.

CR/EPDM/SBR is an economical seal with excellent compression. This material can be used to absorb shocks cushion, deaden sound and seal against, air moisture and light and dust penetration. The blend of Neoprene and EPDM makes this material moderately resistant to oil and ozone.

Characteristics

Sponge rubber is a good water seal under low compression, Acid Resistant, Good sealing qualities, Sound deadening qualities, Resistance to oils and petroleum products.            

Closed cell material Neoprene/EPDM/SBR elastomeric blend meets ASTM D 1056-67, ASTM D 1056-85, 91, 98, 00, MIL-R-6130C, MIL-C-3133C, MIL-STD-670B, UL157, UL50, UL508, UL94HF-1, and FMVSS-302 specifications for military and automotive applications.
