MENU Panacea® Gasketing R-3400 and PP-340 Special Plasticized Vinyl Panacea® R-3400 & PP-340 have been specified and used in pulp mill bleach systems for >50 years. They are a unique compound formulation only available from Prince. Panacea® R-3400 & PP-340 are specified by Chlorine Dioxide technology companies/suppliers and engineering firms who work on pulp chlorine dioxide systems. Special Plasticized, Easy-to-Seal, Black Vinyl Gasketing Material R-3400: EXTRUDED SHEET – 50’ long 48″ Width X 1/4″ (6.4 mm) Thick 60″ Width X 1/16″ (1.6 mm), 1/8″ (3.2 mm), 3/16″ (4.8 mm) Thick PP-340: PRESS-MADE SHEET 1/16 x 36 x 36 in. (1.6 x 914 x 914 mm) Bleaching Pulp Mills often prefer R-3400 when compared to PTFE-based gaskets because R-3400 is: Less expensive Easier to seal Has better compression set Long-term sealability Panacea® R-3400 and PP-340 are available: Extruded Sheet roll stock Press-Made Sheet Full-face pipe flange gaskets Custom fabricated gaskets, extrusions & splicing, such as Explosion Hatch Gaskets (per photo to the left) Tubing, available on a custom-basis Panacea® R-3400 & PP-340 are suitable for Chlorine Dioxide gas and Chlorine Dioxide solution service. They also can be used in many chemical services where PVC is suitable. Check with Prince regarding specific applications. R-3400 & PP-340 6962 Special EPDM Panacea® 6962 is a unique elastomer compounded with a high polymer content (≥53%), with a peroxide cure. Typical service through 300ºF / 149ºC Better sealing ability (compression set), compared to commercial-grade EPDM 6962 is available as gasketing, tubing, hose, expansion joints, as well as molded and fabricated parts. 6962 Recommended Applications for Pulp Bleach Mills: Dilute Chlorine Dioxide Caustic Liquor Sulfuric Acid Methanol Sodium Chlorate Water 6962 Special EPDM PT-G White Bead-Reinforced Fluoroplastic Gasket Material for Service Temperatures up to 500°F / 260°C Prince’s PT-G White PTFE Gasketing Compound with bead reinforcing: The bead reinforcing enables long-term sealing, whereas standard PTFE sheet material tends to creep perpendicularly from flange loading, and then leaks. Displays light flange loading in temperatures from -300ºF/-184ºC up to 500ºF/260ºC. Exhibits a low creep factor under pressure. Easily removed from flanges. Resistance to permanent set. Formable on uneven or warped flanged faces. Maximum sheet size: 60” x 60” (1524 mm x 1524 mm); thickness is 1/8” (3.2 mm) only PT-G White Recommended Applications for Pulp Bleach Mills Chlorine Dioxide Solution, especially in metallic piping PT-G White Gasketing Application Guide LIQUID OR GAS SERVICE USUAL TEMP RANGE PRESSURE SUGGESTED GASKET Liquid Sodium Chlorate Ambient, 50° - 90° F 10° - 32°C to 40 psi 0.28 MPa 6962, PP-340, R3400 Chlorine Dioxide Gas 140° - 18° F 60° - 7.8°C near full Vacuum PP-340, R3400, PT-G White Chlorine Dioxide Solution 45° - 55° F 4.7° - 13° C 0 to 60 psi 0.41 MPa PP-340, R3400 Chlorine Dioxide Solution, heated 0 to 14 gm/l 130° F / 54.4° C >80 psi >0.55 MPa PT-G White, PP-340, R3400 Caustic Scrubber Liquor, or Water Ambient, 50° - 90° F 10° - 32°C 50 psi 0.34 MPa 6962, PP-340, R3400 Chlorine Dioxide/Air Mixture 45° - 55° F 4.7° - 13° C Atmospheric to Slight Vacuum PP-340/R3400 Northern Headquarters Address: 45 Hazelwood Drive Buffalo, NY 14228 USA Phone: +1 (716) 877-7400 Fax: +1 (716) 877-0743 Email: contact@princerp.com Southern Division Address: 11400 Richcroft Ave Baton Rouge, LA 70814 USA Phone: +1 (225) 272-1653 Fax: +1 (716) 877-0743 Email: contact@princerp.com Home Products by Industry Products and Services Technical Resources Company Contact
