Full definition
Generic term for any elastomer piece with a constant cross-section produced by continuous extrusion, encompassing the full range of cross-sectional shapes used in sealing, protection, edge-trimming, and vibration isolation. Common cross-sections: rectangular/flat strip, square, round cord, hollow round (tube), P-shape (bulb seal), D-shape (surface-mount seal), E-shape (channel seal), U-channel (edge protection), L-angle, H-shape (glass channel), and fully custom designs. Materials by application: EPDM (outdoor weatherseals, construction — best weather/ozone resistance), silicone VMQ (oven seals, food equipment, medical — temperature -60 to +230°C), neoprene CR (industrial equipment, cable entry — oil + flame + weather), NBR (oily environments — workshop cabinets, machine enclosures), and sponge/foam (compressible seals — EPDM or neoprene foam). Key specifications: material type, hardness (Shore A), cross-section dimensions with tolerances, color, and continuous temperature rating. Available as solid, sponge, or co-extruded (solid + sponge combined). Standard packaging: coils (10-200 m) or straight lengths. Adhesive-backed versions simplify installation. Per ASTM D2000 for material classification.
