"Panacea" ® 6962 is a SPECIAL compound elastomer of EPDM (Ethylene Propylene, Diene, Monomer), compounded with a high content of polymer exceeding 53%, with a peroxide cure. This unique compounding provides resistance to temperatures through 300 deg. F on a wide range of chemicals and maintains its resistance to compression set better than "commercial" grades of EPDM. 6962 is an ideal material for parts requiring a wide resistance to chemicals utilized and produced in the Chlorine, Caustic, and Bleach Industries. SPECIAL "Panacea"® 6962 material is manufactured into gasketing, tubing, hose, expansion joints, molded shapes, linings and fabricated parts.

For purposes of utilizing 6962 stock in Electrolytic Membrane-type Chlor-Alkali applications, 6962 is compounded without the use of Calcium or Magnesium as ingredients. These types of metals or elements are potentially injurious to fluorobased Membranes; the fact that 6962 is compounded without these ingredients, makes it a prime consideration for Gasketing in Electrolytic Membrane applications.

This SPECIAL compound 6962 EPDM exhibits resistance to most acids, bases and polar solvents such as water, phosphate ester, Ketones, alcohols, and glycols. EPDM swells considerably in aliphatic, aromatic, and chlorinated solvents. This compound is resistant to ozone attack and is weather resistant. We have found that 6962 generally outperforms any "commercial" grade EPDM.
