Perfluoroelastomer (FFKM)

ALLCHEM®

2460 is our general purpose perfluoroelastomer. This compound is best suited for those aggressive environments that do not exceed 250°C. Specify our 2460 series when your applications demand cost savings, chemical resistance and superior physical properties:

ALLCHEM Compound Color Durometer Tensile % PSI Elongation % Compression Set % Temp.
2460-75 Black 75 2750 151 21 250°C
2462-90 Black 90 2685 84 22 250°C
2461-70 White 70 1630 189 22 250°C
2464-80 White 80 1023 187 12 250°C

2470 is our high-temperature perfluoroelastomer. With the introduction of the 2470 series of ALLCHEM®, engineers now have a material that provides the high temperature resistance of a triazine-cured material with the outstanding chemical resistance and physical properties of a peroxide-cured material. This outstanding performance stems from the proprietary "Branching & Pseudo-Living" polymerization technology, which allows for the creation of additional cross-links in the polymer's molecular structure.

ALLCHEM Compound Color Durometer Tensile % PSI Elongation % Compression Set % Temp.
2470-75 Black 75 2126 212 19 320°C
2476-90 Black 90 2291 84 18 320°C
2471-70 White 70 1952 210 35 320°C
2473-75 White 75 1482 228 18 320°C
2474-85 White 85 2483 156 15 320°C

NANOCHEM®

2475 is our line of clear, inorganic-free perfluoroelastomers. A proprietary polymerization process (similar to the branching & pseudo-living technology) produces nano-sized particles that fall below current detection methods. Additionally, NANOCHEM® material lacks the typical fillers found in other elastomeric seals. The absence of these fillers eliminates the problem of significant leachables and extractables common with other perfluoroelastomers.

NANOCHEM Compound Color Durometer Tensile % PSI Elongation % Compression Set % Temp.
2475-70 Clear 70 1530 340 34 250°C
2475-80 Clear 80 758 218 28 250°C

P03

Precix P03 perfluoroelastomer is a peroxide-cured FFKM designed for use in AMS 7257C aerospace applications as well as in chemical processing and applications requiring excellent thermal resistance.

Fluoroelastomer (FKM)

CHEMTEMP®

CHEMTEMP® is based on Dupont's "Viton® Extreme" or Viton® ETP family of polymers. The CHEMTEMP® series is a family of high performance seal compounds that bridges the gap between polymer families. The unique polymer structure of ethylene, tetrafluoroethylene and perfluoromethylvinylether give CHEMTEMP® the broadest fluid resistance of any fluoroelastomer. This unique compound combines the chemical compatibility characteristics of Aflas® and Viton® into one compound.

CHEMTEMP Compound Color Durometer Tensile % PSI Elongation % Compression Set % Temp.
2007-75 Black 75 2900 250 19 230°C

2009-90 Black 90 3700 130 21 230°C

CHEMTEMP ULTRA®

CHEMTEMP ULTRA® is well established in the semiconductor industry, and our Ultra Clean formulation brings metals contamination to the lowest levels of any fluorocarbon based polymer.
