Welcome to the FST Simriz Selector TEST

Legal notice

This guide is 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 Freudenberg-NOK products must conduct their own evaluations to determine application suitability. Additional information can be obtained from other publications such as Chemical Resistance Guide for Elastomers published by Compass Publications.

NOTE: Volume swell 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 temperature and extended exposure times may create more aggressive conditions than cited in this guide. In some cases, specific elastomer compounds within a material family may provide improved compatibility. Please contact Freudenberg-NOK for assistance in choosing the right elastomer for your application. The information given in this chemical compatibility guide is believed to be reliable, but no representation, guarantees or warranties of any kind are made to its accuracy or suitability for any purpose.

Unless otherwise agreed mutually in writing, any technical advice furnished by Seller to Purchaser before or after delivery of the Products is provided “as is” and on a gratuitous basis, without charge, and on the basis that it represents Seller’s good faith judgment, but without warranty of any kind, and is accepted at Purchaser’s sole risk.
