Full definition
Standard-quality polychloroprene rubber sheet or compound for general-purpose, non-critical industrial applications where the balanced property set of neoprene is desired but premium-grade specifications are not required. Typical properties: hardness 40-70 Shore A, tensile 8-15 MPa (lower than premium grades), elongation 200-400%, moderate oil and ozone resistance. Temperature range: -25 to +90°C (somewhat narrower than premium compounds). Commercial grade uses standard W-type CR polymer with moderate carbon black loading and basic protective additives. Cost: 15-30% less than premium or specification-grade neoprene. Available as sheet (1.5-25 mm), strip, and die-cut parts. Applications: general-purpose gaskets (water, air, moderate chemicals), edge protection strips, workbench surface covering, cable management pads, non-critical weatherseals, packaging inserts, and surface protection. Not recommended for applications requiring specific standards compliance (ASTM D2000, MIL, AASHTO) or demanding service conditions (high temperature, continuous oil immersion, structural bearing loads). When in doubt, specify a tested, certified grade rather than commercial.
