The materials of construction displayed are divided into three categories; plastics, elastomers, and metals. It is important to note that plastics and elastomers’ physical characteristics are more sensitive to temperature than metals. For this reason, temperature ratings are listed under each material and must be considered when selecting a thermoplastic material. In most cases it can be assumed that the resistance will be no worse at a lower temperature. Generally speaking, higher temperatures will hasten the corrosion reaction that causes material failure. Therefore, one should not exceed the maximum recommended temperature listed in the guide. Plastics also have low temperature limitations; this guide does not address this issue. If you have specific questions concerning a low temperature application please contact your nearest W. P. Law, Inc. office for recommendations.
This guide uses the following designations:
R = Recommended. This material is recommended for this application at the indicated temperature and chemical concentration.
NR = Not Recommended. This material is not recommended for this application
Dash (-) = Insufficient Data. We do not have sufficient data to make a recommendation.
