World Innovators In Chlor-Alkali Cell Accessories

The relationship between the founder of Prince Rubber & Plastic Co., Inc., Sidney W. Prince and a Hooker Chemical engineer in Niagara Falls, NY ignited in the early 1930's with the need to develop compounds of rubber and plastic materials that could handle the corrosive nature of manufacturing chlorine and caustic soda.
Prince started to develop Panacea® Compounds, which were corrosive resistant rubber and plastic materials that could be made into the necessary parts to manufacture these chemicals. Gasketing, piping systems, flexible hose connectors and more were made with these "Cure-All" materials to the benefit of the plant's overall production.
Prince’s 80 years of advancing these materials, along with the capability of precision fabrication, has benefited Chlor-Alkali Plants worldwide with longer life, reliable cell parts and piping systems. We support all the Electrolytic Technologies of Chlor-Alkali Production and many other Chemical processes, all over the world.

Gaskets for Diaphragm Cell Piping Systems
Diaphragm cell piping gaskets need to be temperature resistant, chemical resistant and non-contaminating to ultra-pure brine and provide long sealing life. Panacea® 6962 Special EPDM exhibits all of these characteristics, and is used widely for hot, wet chlorine gas, ultra-pure brine, hydrogen gas, potassium and sodium hydroxide, and catholyte service.

6962
For purposes of utilizing 6962 stock in Electrolytic Diaphragm-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 Diaphragms; the fact that 6962 is compounded without these ingredients, makes it a prime consideration for Gasketing in Electrolytic Diaphragm applications.
