Different Types of Rubber Sheets and Their Common Uses
Published: August 10 2025
Rubber sheets are versatile, flexible, and durable materials that find their way into countless industries—from automotive and construction to medical devices and food processing. While the term “rubber” often conjures images of a single black sheet, the market actually offers a wide range of formulations, each engineered for specific performance criteria such as temperature resistance, chemical stability, elasticity, and electrical insulation.
Below is a practical guide to the most widely used rubber sheet types, their key characteristics, and the applications where they truly shine. 1. Natural Rubber (NR) Sheets Property Typical Values Highlights Tensile Strength 15–25 MPa Excellent stretchability Elongation at Break 400–800 % Very high elasticity Temperature Range –40 °C to +120 °C Good low‑temperature flexibility Oil/solvent resistance Poor Not suited for petroleum exposure Water resistance Moderate Swells in hot water over time Common Uses
Vibration dampening pads for machinery and appliances.
Sealing gaskets in automotive fuel tanks (where oil resistance isn’t critical).
Conveyor belt liners in food‑processing plants (when food‑grade NR is required).
Footwear components such as midsoles and heel cushions.
Why Choose NR? Natural rubber offers the highest elasticity among all elastomers, making it ideal where large deformations and rebound are required. It’s also biodegradable and relatively inexpensive, though it ages faster when exposed to ozone, UV, and oils. 2. Neoprene (Polychloroprene) Sheets Property Typical Values Highlights Tensile Strength 10–20 MPa Good mechanical strength Elongation 300–600 % Adequate stretch Temperature Range –40 °C to +120 °C Stable in both cold and warm environments Oil/solvent resistance Good (oil, gasoline, solvents) Versatile chemical resistance Weather/ozone resistance Excellent Long outdoor life Common Uses
Marine applications: boat decks, gaskets for pumps, and wetsuit panels.
Electrical insulation: protective covers for cables and panels.
Industrial gasketing: sealing in compressors, pumps, and hydraulic systems.
Protective padding: gym mats, industrial floor protection, and automotive interior trim.
Why Choose Neoprene? Neoprene balances decent elasticity with superior resistance to oils, chemicals, weather, and ozone. Its inherent flame‑retardant properties also make it a go‑to material for many safety‑critical environments. 3. Silicone Rubber Sheets Property Typical Values Highlights Tensile Strength 5–7 MPa Lower than NR/Neoprene but sufficient for many uses Elongation 200–500 % Good flexibility Temperature Range –60 °C to +250 °C (some grades up to +300 °C) Outstanding high‑temp stability Chemical resistance Excellent (water, acids, bases) Not suitable for strong solvents like ketones Electrical properties High dielectric strength, low dissipation factor Ideal insulator Common Uses
Food‑grade seals for ovens, baking trays, and processing equipment.
Medical devices: catheter tubing, wound dressings, and prosthetic liners (biocompatible grades).
Electronics: protective covers, keypads, and insulating pads for circuit boards.
High‑temperature gaskets in aerospace, automotive engines, and industrial ovens.
Why Choose Silicone? Silicone’s ability to retain flexibility over a massive temperature span, combined with its inertness and biocompatibility, makes it indispensable where both thermal stability and safety are paramount. 4. EPDM (Ethylene Propylene Diene Monomer) Sheets Property Typical Values Highlights Tensile Strength 12–25 MPa Strong, long‑lasting Elongation 300–500 % Good stretch Temperature Range –50 °C to +150 °C (some grades up to +200 °C) Broad operating envelope Weather/Ozone resistance Excellent Ideal for outdoor exposure Oil/solvent resistance Poor (hydrocarbon oils) Not for petroleum environments Common Uses
Automotive weather‑stripping (doors, windows, trunk seals).
Roofing membranes and waterproofing membranes.
HVAC ductwork gaskets and sealing for chilled water systems.
Industrial vibration isolators and shock absorbers.
Why Choose EPDM? EPDM excels where exposure to sunlight, ozone, and weather is inevitable. Its resistance to steam, hot water, and many acids/bases makes it a staple for sealing and insulation in building and automotive applications. 5. Nitrile Rubber (NBR) Sheets Property Typical Values Highlights Tensile Strength 10–20 MPa Strong and resilient Elongation 300–600 % Good flexibility Temperature Range –30 °C to +120 °C (hydrogenated grades higher) Moderate Oil/solvent resistance Excellent (petroleum oils, fuels) Prime for oil‑exposed parts Water resistance Moderate Swells slightly in hot water Common Uses
Fuel system gaskets in cars, trucks, and aircraft.
Oil‑resistant seals for hydraulic cylinders and pumps.
Industrial gloves and protective wear (when reinforced).
Food‑grade packaging for oil‑containing foods (certain low‑acrylonitrile grades).
Why Choose Nitrile? Nitrile’s standout oil and fuel resistance makes it the preferred elastomer for petroleum‑related applications, while still offering good mechanical strength. 6. Butyl Rubber (IIR) Sheets Property Typical Values Highlights Tensile Strength 8–12 MPa Moderate Elongation 300–500 % Good stretch Temperature Range –40 °C to +120 °C Stable Air permeability Extremely low (≈0.01 cm³·mm·m⁻²·day⁻¹·atm⁻¹) Superior sealing Chemical resistance Good (water, acids, some oils) Not for aggressive solvents Common Uses
Inner‑tube liners for automotive and bicycle tires.
Airtight gaskets in refrigeration doors, window frames, and HVAC panels.
Protective coatings for pipelines (corrosion‑resistant layer).
Explosive‑ordnance disposal (EOD) blast‑mitigation pads.
Why Choose Butyl? Its exceptionally low gas permeability makes butyl the “air‑tight” choice for applications where leakage must be minimized. 7. PVC‑Coated Rubber Sheets Property Typical Values Highlights Base rubber Usually NR or NBR Provides elasticity Coating thickness 0.3–2 mm PVC Adds chemical and abrasion resistance Temperature Range –30 °C to +80 °C (PVC limits) Moderate Chemical resistance Good to many acids, bases, salts PVC barrier enhances durability Fire rating Often self‑extinguishing (V‑0) Meets many building codes Common Uses
Floor protection in warehouses, workshops, and construction sites.
Protective curtains and splash guards in food‑service kitchens.
Cable trays and conduit liners for underground installations.
Railway and ship‑deck walkways where abrasion resistance is critical.
Why Choose PVC‑Coated Rubber? The combination of a flexible rubber core with a tough PVC skin yields a sheet that can absorb impact while resisting scrapes, chemicals, and fire. 8. Fluoro‑Rubber (FKM/Viton) Sheets Property Typical Values Highlights Tensile Strength 10–20 MPa Strong Elongation 200–400 % Moderate stretch Temperature Range –20 °C to +250 °C (some grades up to +300 °C) High‑temp performance Chemical resistance Excellent to fuels, oils, solvents, acids, bases Industry‑standard for aggressive environments Ozone/UV resistance Very good Long outdoor life Common Uses
Aerospace fuel‑system seals and O‑rings.
Chemical processing plant gaskets for aggressive solvents.
Automotive turbocharger and valve‑train seals.
Pharmaceutical‑grade sealing where contamination must be avoided.
Why Choose Fluoro‑Rubber? When a part must survive extreme temperatures and a corrosive chemical cocktail, FKM is often the only viable elastomer—albeit at a premium price. 9. Specialty Rubber Sheets Type Notable Features Typical Applications Thermoplastic Elastomer (TPE) Sheets Processable like plastic, recyclable Consumer product grips, medical device housings Conductive Silicone/Carbon‑filled Rubber Electrical conductivity, flexible EMI shielding, antistatic flooring, sensor pads Thermal‑Conductive Silicone Embedded thermal fillers (Al₂O₃, BN) Heat sinks for LEDs, power electronics Food‑Grade FDA‑Compliant Rubber (e.g., FDA‑NR, FDA‑Silicone) Meets strict migration limits Baking mats, food‑contact gaskets, packaging Selecting the Right Rubber Sheet: A Quick Decision Guide Requirement Best‑Fit Rubber Type(s) High oil/fuel resistance Nitrile (NBR), Fluoro‑rubber (FKM), Neoprene Extreme temperatures (‑50 °C → +250 °C) Silicone, Fluoro‑rubber, EPDM (low‑temp), Butyl (moderate) Outdoor exposure, UV & ozone EPDM, Neoprene, Fluoro‑rubber Low gas permeability / airtight sealing Butyl, EPDM (moderate) Food‑contact compliance Food‑grade Natural Rubber, Silicone, FDA‑approved TPE Electrical insulation Silicone, EPDM, Neoprene, PVC‑coated Cost‑sensitive general purpose Natural Rubber, Neoprene, PVC‑coated Fire‑resistant flooring PVC‑coated, Neoprene (self‑extinguishing grades) High‑frequency vibration damping Natural Rubber (high elasticity), Neoprene (good damping) Custom shapes & easy machining TPE (thermoplastic processing), Silicone (laser cutting) Emerging Trends in Rubber Sheet Technology

Conclusion
Rubber sheets are far more than “just rubber.” Their diversity in chemistry translates to an equally diverse set of properties—elasticity, temperature tolerance, chemical resistance, and more. By understanding the strengths and limitations of each type, engineers, designers, and procurement professionals can select the optimal material for a given application, balancing performance, durability, and cost.
Whether you need a cheap, highly elastic pad for a vibration‑damping application, a heat‑resistant seal for a medical device, or an ultra‑low‑permeability gasket for a refrigeration system, there’s a rubber sheet formulation ready to meet the demand.
Tip: Always verify the material’s certification (e.g., FDA, UL, ASTM) and request a sample sheet for testing under real‑world conditions before committing to bulk purchases.
