New Klinger Quantum FDA Gasket Sheet

Seal & Design has updated our Thermoseal page to include the Klinger Quantum Gasket sheet.  Quantum was developed by Klinger to bring a high level of flexibility for fiber reinforced gasket materials at high temperatures (662°F continuous service), and the material now complies with FDA food requirements.

The HNBR binder gives the gasket material broad chemical resistance.  We also stock Klinger 4401 and several other sheets for immediate shipment.  Contact Seal & Design to discuss which material would be best suited for your application.

Poron Page Update

PoronSeal & Design has recently updated our Poron page to include PDF data sheets for the most common Poron materials available today.

Poron is a microcellular urethane foam with extremely low compression set. These high density, flexible cellular products are manufactured by continuously casting and curing mechanically frothed urethane intermediates to the desired thickness. By controlling chemistry and density, the properties of Poron materials can be widely varied.

PORON®XRD™ is a breakthrough technology that has been tested to absorb up to 90 percent of energy when impacted at high strain rates. The extreme impact protection is ideal for use in sporting goods and other outdoor industry products.

Chemraz 504 for Low Pressure Valves

Safety Valve

Seal & Design was recently contacted by an OEM valve manufacturer that was experiencing leakage in their low pressure rated valves.  They needed a soft material that had a very broad chemical resistance.  The customer tested Chemraz 504, and it successfully passed their bubble test.

Chemraz 504 has a 65 durometer hardness which makes it ideal for low pressure applications.  The valve manufacturer now specifies Chemra 504 for all seat applications, and Chemraz 505 for their static seals.

Chemraz Page Update

Chemraz O-Rings

Seal & Design has recently updated our Chemraz o-ring page on our website to include the majority of compounds currently available in the market place. Our goal is to become a one-stop shop for information about Chemraz O-Rings, or any of your other seal needs. We have included PDF’s for each Chemraz compound so the physical properties can be viewed, and downloaded at your convenience. Visit our Chemraz O-Ring page for more information.

Chemraz combines the resilience and sealing force of an elastomer with chemical resistance approaching that of PTFE. Chemraz solves some of the most difficult sealing problems in natural gas power generators and truck diesel engines while offering outstanding in-use cost effectiveness through reductions in warranty claims and down time. Chemraz resists attack by nearly all chemical reagents, including inorganic and organic acids, alkalines, ketones, esters, aldehydes, alcohols and fuels. As a result Chemraz provides long-term service in virtually all applications where operating temperatures are elevated and reduced emission requirements are paramount.
