Service Temperature

Limitations for Elastomers

Temperature ranges indicated in the

Service Temperature Limitations table

suggest limits within which the

materi-als will function adequately

Tempera-tures shown are not necessarily inher-ent temperature limits Dynamic forces imposed on the materials are also considered Frequently, tear strength and other physical properties decrease rapidly as service tempera-ture increases.

recommendations cannot be absolute because concentration, temperature, pressure and other conditions may alter the suitability of a

particular metal There are also economic considerations that may influence metal selection Use this table as a guide only A = normally
