Full definition
Sheet produced from styrene-butadiene rubber — the most economical and widely available general-purpose industrial rubber sheet material. SBR sheet offers good abrasion resistance, adequate tensile strength, and acceptable aging for non-critical applications. Properties: hardness 40-80 Shore A (60-70A most common), tensile 5-15 MPa, elongation 200-400%, temperature range -30 to +80°C. Thicknesses: 1.5-25 mm standard. Standard widths: 1,000, 1,200, and 1,500 mm in rolls of 5-20 m. Color: black (standard, carbon black filled). Per ASTM D2000 classification AA/BA. Applications: general-purpose gaskets (water, air — not oil), protective floor coverings, skid-resistant surfaces, workbench tops, bumpers and guards, sound isolation pads, and general fabrication base material. Limitations: poor resistance to oils, fuels, and solvents; poor ozone resistance (not for outdoor exposure without protection). SBR sheet is the default "industrial rubber" when no specific chemical resistance is required. Price: the lowest of all rubber sheet types. Available with or without fabric reinforcement (1-2 ply nylon/polyester for improved tensile and dimensional stability). Major distributors in LATAM: Rubberlac, CCHG, Warco.
