▋ Introduction

When dealing with aggressive fluids the user is continuously faced with the problem of finding compatible materials. In order to simplify the selection of suitable materials when using COVNA products for aggressive fluids, the following tables provide useful information on the optimal choice of housing and gasket materials.

Since corrosion performance is influenced by several factors, the information contained in this brochure should be treated only as a guide and is not necessarily valid for all operating conditions. Increased temperatures, higher concentrations, and the inadvertent ingress of water in originally pure chemicals can accelerate corrosion. Dependent on the purity of the fluid as well as the compounding and nature of vulcanization of the gasket materials, deviations can result which affect the suitability and durability of the plastics and elastomers.

The information quoted in this guide does not consider the effect of mechanical loading, which may also have a bearing on the material performance in the fluid. In cases of doubt when considering our products, we strongly recommend the prior testing of samples with various material combinations, in order to establish and check their suitability under the actual operating conditions of the application.

Where liquid food products are involved, the plastics and elastomers employed must normally conform to the local food and hygiene regulations. It is emphasized that these resistance tables are intended only as a guide and that no guarantees can be given in respect of the information contained in this publication.

▋ Interpretation of Symbols

+

Material little or not affected by chemical: suitable

0

Various attack grades depending on conditions: limited suitability

-

Material shows severe attack: unsuitable this guide assumes in the most cases a temperature of 68°F (20°C). The chemical resistance of materials decreases generally with increasing temperature. If the chemical resistance of a material changes from good to poor depending on the operating conditions (temperature, pressure) or on the concentration and purity of the chemical then the rating 0 will be given.

▋ References

All the information quoted in these resistance tables is based on industrial experience or other providers and supplemented by Internet searches and other sources of information own.

The following chemical resistance tables are divided into three categories, standard chemicals, Industrial Chemicals and liquid foods and beverages. Materials used seldom in our products (e.g. aluminum) are not described in detail in the tables. In such cases, chemical resistance information related to a particular application or product should be requested. The same applies to nickel-plated and chromium-plated components. The materials PTFE (Teflon) and epoxy resin are also excluded. Both are resistant to most common chemicals and can be employed in the majority of applications. Chemicals to which these materials are not resistant are mentioned in the following summary.
