EPE Rubber sheets

Rubber Sheet for Insulation

Product Description: Rubber Sheets for insulation are high-performance materials designed to provide excellent electrical and thermal insulation. These sheets are made from various rubber compounds, such as EPDM (Ethylene Propylene Diene Monomer), NBR (Nitrile Butadiene Rubber), SBR (Styrene Butadiene Rubber), or Neoprene, depending on the specific requirements of the application. Rubber sheets are widely used in electrical, automotive, and industrial applications for insulating and protecting sensitive components from temperature fluctuations, electrical current, and physical stress.

These sheets are flexible, durable, and resistant to a range of environmental conditions, including moisture, oils, and chemicals, making them ideal for applications in harsh environments. Rubber sheets are typically used in electrical insulation, vibration isolation, gasketing, and sealing applications.

Key Features:

• Electrical Insulation: Provides excellent dielectric strength to prevent electrical leakage and shorts.
• Thermal Insulation: Protects against temperature extremes, offering reliable thermal resistance.
• Durability and Flexibility: Tough and flexible, able to withstand mechanical stresses, wear, and abrasions.
• Chemical and Oil Resistance: Highly resistant to oils, chemicals, and water, making it suitable for industrial and automotive uses.
• Moisture Resistance: Closed-cell structure provides resistance to moisture absorption.
• Vibration Dampening: Effective at absorbing vibrations and reducing noise in machinery and electrical systems.
• Non-toxic: Safe for use in environments such as food processing, healthcare, and consumer products.
• Customizable: Can be cut or molded into various shapes and sizes to suit different applications.

Technical Specifications:

• Material Composition:

  • Depending on the grade, materials include EPDM, NBR, SBR, Neoprene, or a combination of synthetic rubbers.

• Thickness Range:

  • Available from 0.5mm to 50mm, with custom thickness options available on request.

• Dimensions:

  • Standard sheet sizes: 1000mm x 1000mm, 1200mm x 1200mm, 1220mm x 2440mm (custom sizes available).

• Density:

  • Typically 1.2 – 1.5 g/cm³, depending on material type.

• Temperature Resistance:

  • -40°C to 120°C, with some rubber grades able to withstand up to 200°C for short periods.

• Dielectric Strength:

  • Typically 15-25 kV/mm depending on material and thickness.

• Tensile Strength:

  • 10 – 20 MPa depending on the material and compound.

• Elongation at Break:

  • Typically 200 – 500% depending on the rubber grade.

• Compression Set:

  • Generally < 30% after 22 hours at 70°C, which indicates the material’s ability to maintain its shape under compression.

• Hardness:

  • Shore A hardness ranging from 40 to 80 (depending on material and application).

• Flame Resistance:

  • Fire-retardant grades available that meet UL 94-V0 or equivalent standards.

• Chemical Resistance:

  • Highly resistant to oils, acids, alkalis, water, and ozone exposure. Specific resistance varies with rubber type (e.g., NBR is highly resistant to oils, while EPDM resists weathering and UV).

• Moisture Absorption:

  • < 1% by weight for most grades.

• Soundproofing:

  • Effective in reducing noise and vibrations, especially in industrial machinery and electrical systems.

• Color:

  • Typically black or grey, but other colors can be customized upon request.

• Recyclability:

  • Depending on the rubber type, most rubber sheets are recyclable.

Applications:

• Electrical Insulation: Insulating cables, transformers, and electrical panels.
• Thermal Insulation: Protecting pipes, tanks, and other equipment from extreme temperatures.
• Vibration Isolation: Used in machinery, compressors, and electrical equipment to reduce vibration and noise.
• Gaskets and Seals: For use in industrial and automotive applications where sealing against fluids, air, or gas is required.
• Automotive Parts: Insulating rubber sheets used in engine compartments and under-hood parts.
• Construction: Used for insulating floors, walls, and roofs.
• Safety Mats: Used in industrial environments for electrical safety and preventing slipping.

These rubber sheets for insulation provide excellent performance across a wide range of industrial, electrical, and mechanical applications. They are designed to enhance safety, durability, and energy efficiency. Let me know if you need more specific details on any particular grade or application!
