EPDM Rubber Sheet Manufacturers and Suppliers
Deesawala Rubber manufactures EPDM rubber sheet, a synthetic rubber which is known for its passive chemical properties. The product offers remarkable resistance to weathering and a good performance. They exclude contact with oils and fuels.
Here are some key benefits of EPDM sheet.
Deesawala EPDM (Ethylene Propylene Diene Monomer) rubber sheets are utilized by diverse industries. They are equipped with incredible features such as heat resistance, weather resistance, electrical insulation properties, etc. Take a quick glance at some general specifications as well as data for rubber sheet EPDM.
Material Composition:
EPDM: Ethylene Propylene Diene Monomer
Physical Properties:
- Density: Typically ranges from 0.9 to 1.5 g/cm³
- Firmness: Shore A 45 to 90. It is a commonly used range
- Tensile Strength: Usually, 7 to 15 MPa
- Elongation at Break: Typically, 200% to 400%
- Tear Strength: Typically, 15 to 50 N/mm
- Compression Set: Shows good resistance to compression set, maintaining its original shape after compression.
Temperature Range:
Deesa EPDM rubber sheets have capabilities to withstand temperatures that may range from -40 °C to +120°C (-40°F to +248°F). The extended temperature ranges may be offered by the specialized grades.
Weather Resistance Properties:
EPDM rubber sheets can easily resist ozone. They can also resist UV exposure and weathering. They are absolutely suitable for various types of outdoor applications.
Chemical Resistance Properties:
EPDM rubber sheets are equipped with good resistance to water, steam, mild acids, and alkalies. But they might not be advisable for use with petroleum-based fluids and hydrocarbon solvents.
EPDM Sheet Applications:
EPDM (Ethylene Propylene Diene Monomer) rubber sheets have exceptional properties. Hence, they are used across different industries. Here is your comprehensive guide on some of the common applications of EPDM sheets.
- Pipeline Gaskets and Seals: They are used in water pipelines, automotive, machinery. They serve as superior sealing solution against water, weathering, and chemicals.
- EPDM Membrane Sheets: The products are employed in roofing systems. This is because they are durable and weather resistance. They deliver long-term performance in flat and green roofing applications.
- Weatherstripping: Used in doors, windows, and other openings to seal against air, water, and dust infiltration, these products are engineered to enhance energy efficiency and also reduce noise transmissions.
- Electrical Insulation: It is known for excellent electrical insulation properties, employed in wires, cables, connectors, and electrical components.
- Automotive Components: EPDM sheet is widely used in automotive industry for door seals, window seals, weatherstripping, engine gaskets, and vibration-dampening components. These sheets hold resistance to heat, weathering and chemicals.
- Expansion Joints: They are also used in HVAC systems for ducting, gaskets, seals, and insulation. The product is capable of withstanding diverse temperatures. It exhibits remarkable resistance to moisture and chemicals.
- HVAC (Heating, Ventilation, and Air Conditioning): The sheets are utilized in construction and infrastructure projects for expansion joints. They can accommodate thermal expansion and contraction; they still maintain a watertight seal.
- Marine Applications: Applicable in marine environments for hatch seals, gaskets, and fender strips, the sheets are resistant to water, UV exposure and weathering.
