CHEMICAL COMPATIBILITY GUIDE

CHEMICAL COMPATIBILITY TABLES

These tables are intended to assist the user in determining the suitability of various elastomers in many different chemical environments. The ratings are based on a combination of published literature, laboratory tests, actual ﬁeld experience, and informed judgments. As laboratory tests do not necessarily predict end-use performance, users of DICHTOMATIK products should conduct their own evaluations to determine application suitability. NOTE: Ratings are based on volume swell which is only one indicator of elastomer ﬂuid compatibility and may be based on the solubility parameter alone. Fluid attack on the backbone of the polymer may show up as a change in physical properties such as tensile strength, elongation at break, and hardness. Elevated temperatures and extended exposure times may create more aggressive conditions than cited in this guide. This information is believed to be reliable, but no representation, guarantees or warranties of any kind are made to its accuracy or suitability for any purpose. The information presented is based on laboratory testing and does not necessarily indicate end product performance. It is recommended that users of DICHTOMATIK products conduct their own evaluations to determine suitability for the intended application.

COMPATIBILITY RATING SYSTEM

RATING DESCRIPTION VOLUME CHANGE COMMENTS

1 Little or no effect <10% Elastomer may exhibit slight swelling and/or loss of physical properties under severe conditions.

2 Possible loss of 10–20% Elastomer may exhibit swelling in addition to a physical properties change in physical properties. May be suitable for static applications.

3 Noticeable change 20–40% Elastomer exhibits a noticeable change in swelling and physical properties. Questionable performance in most applications.

4 Excessive change >40% Elastomer not suitable for service.
