Full definition
A generic commercial term encompassing the broad range of elastomer sheets, rolls, profiles, and fabricated parts used across manufacturing, processing, and engineering applications. Standard forms: (1) Sheet/slab — calendered or press-cured, thicknesses 1.5-50 mm, widths 1,000-1,500 mm, lengths 5-20 m rolls; (2) Roll — continuous rolled sheet; (3) Strip — slit from sheet to specific widths; (4) Die-cut gaskets and pads; (5) Extruded profiles; (6) Molded parts. Materials: SBR (general purpose, most economical), NR (best abrasion and tear), NBR (oil-resistant), EPDM (weather/steam-resistant), neoprene CR (balanced properties), silicone VMQ (temperature extremes), and PU (maximum abrasion). Standard thicknesses in Mexico and LATAM: 1.5, 2, 3, 4.5, 6, 8, 10, 12, 15, 19, 25 mm. Hardness: 40-80 Shore A typical. Optional: fabric reinforcement (1-2 plies nylon or polyester) for higher tensile strength and dimensional stability. Applications: gaskets, flooring, conveyor skirting, chute linings, vibration pads, bench tops, and protective covers. Sold by the meter, sheet, or custom-cut piece. Per ASTM D2000 for material classification.
