A rubber sheet is a versatile, high-performance industrial and commercial material, engineered from elastomeric compounds and fabric reinforcements to provide exceptional durability, resilience, and protection. Its primary function is to serve as a reliable barrier and lining, offering critical properties such as shock absorption, noise reduction, chemical resistance, electrical insulation, waterproofing, and anti-slip safety. Manufactured through processes like calendaring, vulcanization, and lamination, the sheet's characteristics are defined by its base polymer: natural rubber (NR) for general resilience, styrene-butadiene rubber (SBR) for abrasion resistance, nitrile rubber (NBR) for oil and fuel resistance, neoprene (CR) for weather and flame resistance, and ethylene propylene diene monomer (EPDM) for superior ozone and temperature resistance. A key variant is the (fabric-reinforced rubber sheet), where embedded fabric layers—like polyester or nylon—significantly enhance tensile strength and dimensional stability for heavy-duty mechanical applications. 　　Technically, industrial rubber sheets are available in a wide range: thickness from 1.5mm to 80mm, widths from 500mm to 2000mm, and in standard colors like black or green. They are categorized into over 15 functional types, including standard, oil-resistant, acid/alkali-resistant, and heat-resistant grades. Common specifications include a specific gravity of 1.4-1.6 and a hardness of 70°±5° Shore A. For electrical safety, insulating rubber sheets are paramount; an 8mm-thick sheet must withstand 10,000V for one minute in a 10KV environment, while a 12mm sheet endures 15,000V, with a reliable operational temperature range from -35°C to +100°C and a surface free from conductive imperfections. 　　The applications are extensive across industries. In aerospace, automotive, and marine sectors, they are used as gaskets, seals, and protective linings. In construction and civil engineering, they function as waterproofing membranes, expansion joints, and anti-vibration pads for machinery. In electrical engineering, they are indispensable as insulating floor mats in substations and配电室 (distribution rooms). Furthermore, in commercial settings, products like ARCADE™ Rubber Sheet Flooring provide slip resistance, sound absorption, and underfoot comfort in hospitals, schools, and gyms. Modern manufacturing also explores sustainable materials, such as incorporating natural rubber seed oil—a by-product with antioxidant properties—enhancing the material's environmental profile. In summary, from ensuring worker safety in high-voltage environments to dampening vibrations in heavy industry and providing quiet, safe flooring in public spaces, the rubber sheet is a fundamental, multi-functional engineering solution that masterfully balances mechanical performance, environmental resistance, and adaptive functionality.
