Overview
Fiber rubber sheet is a composite material consisting of rubber (natural or synthetic) reinforced with fibers such as cotton, polyester, or aramid. This combination enhances mechanical properties, making it ideal for demanding industrial applications. The material is valued for its ability to withstand compression, resist chemicals, and provide long-term durability. Common rubber types used include nitrile, EPDM, and neoprene, each offering distinct advantages like oil resistance or temperature stability. The embedded fibers improve tear resistance and dimensional stability, ensuring reliable performance in gasketing and sealing tasks.
Physical and Chemical Properties
Fiber rubber sheets exhibit high tensile strength due to fiber reinforcement, with typical values ranging from 10-20 MPa. They maintain flexibility across a wide temperature range (-40°C to +120°C, depending on the rubber type). The material is resistant to oils, acids, and alkalis, making it suitable for harsh environments. Density varies slightly based on fiber content but generally falls between 1.2-1.5 g/cm³. The sheets are non-conductive and provide excellent vibration damping, which is critical in machinery and automotive applications. Their insolubility in water and solvents ensures longevity even in wet conditions.
Main Applications
Primary uses include gaskets for pipelines, pumps, and engines, where the sheet’s resilience ensures leak-proof seals. In automotive and aerospace industries, it serves as vibration dampers and padding to reduce noise and wear. The construction sector employs it for expansion joints and roofing membranes. Additional applications include conveyor belt linings, industrial flooring, and protective padding in heavy machinery. Its adaptability to die-cutting allows for custom shapes, meeting precise engineering requirements across sectors.
Safety and Storage
While generally safe, some rubber compounds (e.g., chloroprene) may release irritants during cutting or heating. Use proper ventilation and PPE like gloves when handling. Storage should avoid extreme temperatures and UV exposure to prevent premature aging. Sheets should be stacked flat to prevent deformation and kept away from ozone-generating equipment (e.g., electric motors). Shelf life typically exceeds 5 years if stored correctly. For food-grade applications, ensure compliance with FDA or EU regulations.
B2B Procurement Guide
When sourcing fiber rubber sheets, specify thickness (commonly 1-10 mm), fiber type (e.g., polyester for chemical resistance), and rubber compound. Bulk orders often attract discounts, with MOQs starting at 100 square meters. Lead times vary but average 2-4 weeks for custom formulations. Verify supplier certifications like ISO 9001 and request material test reports (MTRs) for critical parameters like tensile strength and compression set. For cost-sensitive projects, recycled rubber options are available but may sacrifice performance. Sample testing is recommended before large-scale procurement.
