Peroxide Cured EPDM

EPDM (Ethylene Propylene Diene Monomer Rubber) is the mainstay material used for aqueous (water) high-purity processing.  Newman Sanitary Gasket Company manufactures FDA and USP Class VI compliant rubber sanitary gaskets, O-rings and custom molded partsmade from a series of proprietary peroxide-cured EPDM compounds of various hardness ranges (50 to 90 Shore A).  These components provide superior purity, properties, and performance.  They are resistant to aqueous acids and bases, steam, oxygenated sanitizing solutions, and a host of other polar solvents. EPDM has an excellent temperature range from -55 °F (-48 °C) up to +325 °F (162 °C) and some grades are specialized for the Biopharmaceutical Industry. Newman 2107 EPDM (70 Durometer Black) has been the material of choice for FDA and USP applications for decades around the world.

2107 LE (Low Extractable) Products

Building on the experience of Newman 2107, 2107LE is setting a new standard for Biopharmaceutical applications. Specifically designed to protect the process, the product and the patient. With 10% of the extractables (LE = Low Extractables) of normal EPDM, 2107LE provides the added benefits of an extended temperature range, easier installation and removal, better equipment support and a longer lifetime while in process.  Fully synthetic, 2107LE complies with a multitude of international regulations, standards and customer requirements (e.g. FDA, USP, EU, EP, REACH, RoHS I and II, ICH Q3D Residual Solvents and Elemental Impurities, Free of ADI, Latex, BPA, Phthalates, etc.). 2107LE also meets global requirements for biopharmaceutical processing.

Compatible with CIP, SIP, WFI and Processing areas:

  • Lower Extractables
    • 10X less than conventional formulations
    • Longer Service Life
    • Little to no wear after 500 pure steam exposure cycles (ASME BPE Appendix K)
    • Better dimensional stability
    • Little to no intrusion into the process stream
  • Easier Maintenance
    • 2107LE EPDM sanitary gaskets disassemble after long periods of exposure with little effort (static friction) and no residue on fittings
    • 2107LE supports the weight of equipment better and holds tubing in alignment better than other compounds, all without cracking or tearing

Post Cure

Newman an EPDM, FDA, and Rubber Gasket Manufacturer, process provides for a second step in the vulcanization (the curing process of raw rubber) process for high-end elastomer parts, called post-curing.  This provides stronger parts and drives off unwanted residual materials from the curing process.  As a result, the parts have lower extractables and leachables, greater resistance to compression set, and greater tensile strength and modulus. It increases performance of the part.

Newman's compounds are specially formulated for high performance.  Resisting the temptation to use high amounts of cheap fillers that cause a seal to fail earlier, Newman compounds are designed to last:  to give long, reliable, and robust service.
