* Elastomeric Compounds:
Each of these materials has its own unique properties that allow them to provide long life and excellent service. Let’s have a quick look.
FDA FKM has a temperature range of -10F to +450F, and provides excellent resistance to a wide variety of chemicals. It is excellent for steam and widely used in the Pharma and Bio industries. FKM also provides good resistance to micro-organisms, certain solvents and ozone.
EPDM (Ethylene, propylene) materials offer a temperature range of -20F to +300F and offer excellent resistance to high temperatures ozone, weathering and saturated steam, making it ideal for use with foods and pharmaceutical processes. Unsuitable for petroleum based oils, mineral oil.
Food Quality Silicone materials provide excellent resistance to extreme weather conditions, ozone, oxygen, UV light and moisture. It offers temperature resistance from -80F to +370F. It also offers resistance to bases and acids at average temperature and concentration. Weak mechanical properties limit its tensile, tear and abrasion resistance.
Polytetrafluorethylene (PTFE) is actually a white polymer that is the most chemically resistant compound available and offers a wider range of temperatures than elastomers. PTFE can withstand temperatures from -60F to +400F. It is resistant to most chemicals and solvents and its tensile strength makes it an excellent choice for applications that require a high occurrence of friction. Its very low compression set and its dimensional behavior limit its applications.
