Full definition
A rectangular-cross-section piece of vulcanized rubber produced by slitting from calendered or press-cured sheet, or by direct extrusion, and sold by the linear meter or in pre-cut lengths. Dimensions: widths 10-300 mm, thicknesses 1.5-25 mm, in continuous rolls (typically 5-50 m) or cut pieces. Materials: SBR (general purpose, economical), NR (best abrasion and resilience), neoprene CR (oil + weather resistance), NBR (oil and fuel resistance), EPDM (weather and steam), and silicone VMQ (temperature extremes, food grade). Hardness: 40-80 Shore A. Edges: slit (cut from sheet — slightly rough) or extruded (molded — smooth and precise). Adhesive-backed versions available (PSA on one or both sides) for easy installation. Applications: sealing strips for doors, windows, and hatches; bumpers and edge guards; wear strips on machinery; conveyor skirting (thick NR strips); anti-vibration pads; and weather sealing for outdoor enclosures. Custom sizes and materials available by special order. Per ASTM D2000 for material classification. Tolerances: ±0.5 mm on width and ±0.3 mm on thickness for slit strips; ±0.2 mm for extruded profiles.
