CHEMICAL RESISTANCE GUIDE

CRG-MR1-1w

This guide is designed as an aid in selecting common elastomers used to conduct some of the many types of materials found in industry.

Improper selection of tube and/or cover materials can result in decreased service life, or complete failure of the expansion joint.  For example, Natural Rubber is an excellent tube material for water lines.  If however, the water contains concentrations of non-degradable oil, the rubber will swell and deteriorate.  In this instance a Nitrile tube should be used.  If his expansion joint were installed outdoors, the cover elastomer would be subject to ozone and weathering which would rapidly age harden both Natural Rubber and Nitrile.  These cover materials could become brittle, crack and crumble.  EPDM would be the proper choice for an outdoor cover.  While Freon is chemically compatible with some elastomers, we never build Freon connectors because of mechanical problems.

In selecting a proper elastomer, total system environment must be considered.  While theoretically safe, some applications may be inadvisable because of worker safety or extensive property damage.

The information in this selection guide was derived from published literature of Polymer suppliers, and in some cases the considered opinions of experience of the Mercer Rubber Company. Therefore, this guide in intended only as an aid in selecting proper elastomers.  We encourage our customers to test samples of a selected elastomer for compatibility with the actual service, and we would be pleased to provide small sample test pieces on request.

We feel this guide is an excellent source of general information, but Mercer Rubber Company cannot be held responsible should your specific experience disagree with these generalizations.
