We manufacture our extruded, custom window glazing gaskets using BUNA-N, EDPM, nitrile, Neoprene 1, SBR, and silicone. We have the capability to formulate custom compounds if one of the standard rubber formulations or compounds does not meet your requirements. Materials are available in commercial and specification grades to meet industry and regulatory standards, including Mil Spec, FDA, USDA, 3A Sanitary, UL, NSF, ASTM [D-2000], SAE, AMS, FMVSS, and industry-specific standards for smoke, flame, and toxicity.
