What is EPDM Rubber?

EPDM (Ethylene Propylene Diene Monomer) rubber is a type of synthetic rubber known for its excellent weather resistance, flexibility, and durability. It is widely used in various sealing applications.

Characteristics of EPDM Rubber

  1. Weather Resistance: EPDM rubber is highly resistant to environmental elements such as UV radiation, ozone, and extreme temperatures, making it ideal for outdoor applications.

  2. Flexibility: It maintains its flexibility and elasticity over a wide temperature range, ensuring consistent sealing performance in both hot and cold conditions.

  3. Water and Steam Resistance: EPDM rubber exhibits excellent resistance to water, steam, and moisture, preventing degradation and maintaining its sealing properties.

  4. Chemical Resistance: It is resistant to a variety of chemicals, including acids, alkalis, and polar solvents, which enhances its versatility in different industrial environments.

  5. Thermal Insulation: EPDM rubber provides good thermal insulation, helping to maintain temperature control and reduce energy loss.


  1. Automotive Industry: Used in weatherstripping, door and window seals, hoses, and gaskets to provide a reliable seal against environmental elements and reduce noise and vibration.

  2. Building and Construction: Applied in roofing membranes, window seals, and joint fillers to ensure waterproofing, insulation, and protection from weather conditions.

  3. HVAC Systems: Utilized in sealing ducts, pipes, and insulation materials to improve energy efficiency and prevent air and moisture leaks.

  4. Industrial Equipment: Employed in sealing applications for machinery and equipment that require resistance to weather, chemicals, and temperature fluctuations.

  5. Electrical Insulation: Used in sealing and insulating electrical components to protect against moisture and environmental factors.


  1. Durability: EPDM rubber offers a long lifespan due to its resistance to aging, weathering, and chemical exposure.

  2. Versatility: Its ability to perform well in a variety of environments makes it suitable for a wide range of sealing applications.

  3. Cost-Effective: EPDM rubber provides an economical solution for sealing needs, offering a good balance between performance and cost.

  4. Low Maintenance: Its resistance to environmental factors reduces the need for frequent maintenance and replacement.

用英文介绍一下NBR&CR Molded rubber

Certainly! Here's an introduction to NBR and CR molded rubber in English:

NBR & CR Molded Rubber Overview

What is NBR Rubber?

NBR (Nitrile Butadiene Rubber) is a synthetic rubber known for its excellent resistance to oils, fuels, and other chemicals. It is commonly used in applications requiring durability and resistance to harsh substances.

What is CR Rubber?

CR (Chloroprene Rubber), also known as Neoprene, is another type of synthetic rubber that is highly valued for its versatility, resistance to weathering, chemicals, and temperature extremes.

Characteristics of NBR Molded Rubber

  1. Oil and Fuel Resistance: NBR rubber is highly resistant to oils, fuels, and other petroleum-based products, making it ideal for automotive and industrial applications.

  2. Durability: It exhibits good mechanical properties, including abrasion resistance and tensile strength.

  3. Temperature Range: NBR performs well in temperatures ranging from -40°C to 108°C (-40°F to 226°F).

  4. Flexibility: Maintains flexibility and resilience under stress and repeated use.

Characteristics of CR Molded Rubber

  1. Weather Resistance: CR rubber is resistant to UV radiation, ozone, and various weather conditions, making it suitable for outdoor use.

  2. Chemical Resistance: It resists a wide range of chemicals, including acids, alkalis, and solvents.

  3. Temperature Stability: CR performs well in a broad temperature range from -40°C to 121°C (-40°F to 250°F).

  4. Flame Resistance: CR rubber is inherently flame-resistant, which is beneficial in many industrial applications.


  1. Automotive Industry:

    • NBR: Used in fuel hoses, gaskets, seals, and O-rings due to its oil and fuel resistance.

    • CR: Applied in belts, hoses, and weatherstripping because of its weather resistance and durability.

  2. Industrial Equipment:

    • NBR: Utilized in hydraulic systems, oil seals, and gaskets.

    • CR: Employed in equipment that requires resistance to chemicals and environmental factors.

  3. Construction:

    • NBR: Used in construction machinery seals and gaskets.

    • CR: Applied in roofing, bridge bearings, and vibration isolation materials.

  4. Marine Industry:

    • CR: Used in wetsuits, gloves, and other protective gear due to its water and weather resistance.

  5. Electrical Insulation:

    • CR: Used in insulating materials and cable jackets due to its electrical properties and flame resistance.


  1. Versatility:

    • NBR: Ideal for applications requiring oil and fuel resistance.

    • CR: Suitable for a wide range of applications due to its weather, chemical, and flame resistance.

  2. Durability: Both materials offer long-lasting performance in demanding environments.

  3. Cost-Effective: Provide an economical solution for various sealing and insulating needs.
