Armored Fluoroplastic Encapsulated "69" series
The fluoroplastic 69 series gasket product series was developed to provide the ultimate chemical resistance of a fluoroplastic such as PTFE or FEP, combined with compression set, temperature range, and chemical resistance of the Prince Panacea® "69" Series EPDM for long-life, reliable seals.

Typical applications for this product configuration are found in the Chlor-Alkali industry for anode gaskets and the Chlorate Industry for electrolyzer gaskets. For gasket applications that require very inert materials such as PTFE and FEP in contact with the client’s product combined with the compression set, temperature range, and chemical resistance of the Prince Special "69" Series EPDM for long-life, reliable seals.

A typical application for this product configuration is ultra-pure chemical production for the computer microchip industry.

PDFSpecial 1475 TFE-P Copolymer
This compound of Tetrafluoroethylene Elastomer differs greatly from other fluorocarbon elastomers because it does not contain Hexafluoropropylene or vinylidine Fluride.

(See Gasketing Material for More Info)

• PT-G white gasketing material contains inorganic round beads, consistently disbursed throughout a PTFE base.

• This special PTFE Fluoroplastic compound is utilized in highly corrosive environments with temperatures up to 500°F.

• Its resistance to permanent set, low creep under pressure and its ability to form on uneven or warped flanges is what it is known for.

• PT-G White sheet is available in 1/16”, 1/8” thick sheet by 48”x 96”or 48”X 48” or cut gaskets


PDFPT-70-M "Easy to Seal" PTFE Protected EPDM Gaskets

Panacea® Advanced
Replacement Membrane Cell Gasket Systems

Molded Replacement Gaskets for Popular Chlor-Alkali Electrolyzers are advanced by Prince’s technology of using Panacea® proprietary compounds of rubber gasketing materials that increase the life of the material. Prince’s advanced methods of increasing the security of the fluoroplastic shields are done by extending the length of the shield and by sealing more of the sealing face.

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. Prince 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.

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.
