EPDM Rubber Sheet Manufacturers and Suppliers
What is EPDM Rubber Sheet :
Deesawala Rubber manufactures EPDM sheets, synthetic rubber with very inert chemical properties that offer excellent weathering resistance and good all-around performance, except with fuels and oils. We give you an overview of the advantages of EPDM sheeting below.
Deesawala brand EPDM (Ethylene Propylene Diene Monomer) rubber sheets are widely used in various industries for their excellent weather resistance, heat resistance, and electrical insulation properties. Here are some general data and specifications for EPDM rubber sheets
-
1.Material Composition as under
- EPDM: Ethylene Propylene Diene Monomer 2.Physical Properties:
- Density: Typically ranging from 0.9 to 1.5 g/cm³
- Hardness: Shore A 45 to 90 (commonly used range)
- Tensile Strength: Typically 7 to 15 MPa
- Elongation at Break: Typically 200% to 400%
- Tear Strength: Typically 15 to 50 N/mm
- Compression Set: It provides Good resistance to compression set (the ability to return to its original shape after compression) 3.Temperature Range:
- Deesa EPDM rubber sheets can generally withstand temperatures ranging from -40 °C to +120°C (- 40°F to +248°F). Some specialized grades may also offer extended temperature ranges 4.Weather Resistance Properties
- EPDM rubber sheets resist weathering, ozone, and UV exposure, rendering them well-suited for outdoor applications. 5.Chemical Resistance Properties
- EPDM rubber sheets offer good resistance to water, steam, mild acids, alkalies, etc. However, they are not recommended for petroleum-based fluids and hydrocarbon solvents.
EPDM Sheet Uses
EPDM (Ethylene Propylene Diene Monomer) rubber sheets are widely used in different industries for their excellent properties. Here are some common applications of EPDM sheets.
Pipeline Application Gaskets and Seals: EPDM sheets are commonly used to create gaskets and seals in water pipelines and automotive, machinery, and industrial applications. They provide excellent sealing properties and resistance to water, weathering, and chemicals.
EPDM Membrane Sheets: Deesawala Rubber Manufacturers EPDM Membrane sheets are used in roofing systems for their durability, weather resistance, and long-term performance. They can be used in flat, green, and other roofing applications.
Weatherstripping: EPDM sheets are used as weather stripping in doors, windows, and other openings to seal against air, water, and dust infiltration. They help improve energy efficiency and reduce noise transmission.
Electrical Insulation: EPDM sheets have excellent electrical insulation properties, making them suitable for electrical applications. They can be used as insulation for wires, cables, connectors, and electrical components.
Automotive Components: EPDM sheets are widely used in the automotive industry for various applications such as door seals, window seals, weatherstripping, engine gaskets, and vibration-dampening components. They provide excellent resistance to weathering, heat, and chemicals commonly found in automotive environments
Suitable for Expansion Joints: EPDM sheets are used in HVAC systems for applications such as ducting, gaskets, seals, and insulation. They can endure a diverse range of temperatures and exhibit excellent resistance to moisture and chemicals.
HVAC (Heating, Ventilation, and Air Conditioning): EPDM sheets are used in construction and infrastructure projects for expansion joints. They can accommodate movements caused by thermal expansion and contraction while maintaining a watertight seal.
Marine Applications: Deesawala EPDM sheets are used in marine environments for applications such as hatch seals, gaskets, and fender strips. They provide resistance to water, weathering, and UV exposure.
