Product Advantages

  • 图文组件

    Closed-cell structure

    The EPDM foam sponge has a closed-cell structure, meaning that there are no interconnected channels between its cells. This structure allows the material to quickly recover its original shape after compression while providing outstanding sound insulation and insulation properties.

  • High elasticity

    The EPDM foam sponge exhibits exceptional elasticity and resilience, maintaining its shape and performance even after prolonged compression or stretching.

  • Outstanding temperature resistance

    Our EPDM closed-cell foam sponge material offers excellent high and low-temperature resistance, remaining stable within a temperature range of -45°C to 182°C. This enables it to deliver superior insulation, sealing, and cushioning performance even in extreme temperature environments.

  • Multiple product forms available

    Our EPDM closed-cell foam sponge material is available in various forms such as blocks, sheets, and rolls, providing customers with options to suit different application scenarios.

Main applications

  • 图文组件

    Automotive industry

    EPDM foam sponge is widely used in the automotive industry as a material for sound insulation, vibration damping, and sealing. It effectively reduces interior noise and vibration transmission, enhancing the overall driving experience.

  • Electronics and electrical equipment

    EPDM foam sponge is utilized in electronic products as a material for shock absorption and sound insulation, protecting circuit boards and components from external vibrations and noise.

  • Construction and building materials

    EPDM foam sponge serves as a sound insulation material in buildings, factories, and control rooms, reducing noise propagation and creating better acoustic environments.

  • Other fields

    EPDM foam sponge also finds applications in various other sectors such as electrical manufacturing, aerospace, and sports equipment.

Customization options

  • Density selection

    The density of EPDM foam sponge can be customized (ranging from 70-200kg/m³) to meet specific application requirements. Lower density sponges offer better flexibility and compression performance, suitable for applications that require higher shock absorption and cushioning effects. Higher density sponges provide increased elasticity and hardness, suitable for applications that require better support and durability.

  • Hardness customization

    Based on customer requirements, EPDM foam sponge can be tailored to different hardness levels (Shore hardness 10-20). Sponges with different hardness are suitable for various application scenarios, allowing customers to choose the most suitable product based on the desired softness or hardness.

  • Single-sided or double-sided skin

    We can apply leather coating on one or both sides of the sponge based on customer needs. This enhances the sponge's abrasion resistance and durability, extending the product's lifespan, while also providing more design options.

  • Sulfur-free products

    For certain special applications that demand sulfur-free materials, we offer sulfur-free EPDM closed-cell foam sponge to ensure product purity and stability. Sulfur-free materials have no corrosive effect on metal components wrapped in foam.
Our EPDM closed-cell foam sponge material is highly regarded for its exceptional performance, diverse customization options, and wide range of applications. Whether in the automotive industry, electronics and electrical equipment sector, or construction and building materials field, EPDM foam sponge proves to be a reliable choice. We are committed to meeting customer requirements and providing tailored solutions to ensure optimal performance and effectiveness. Whether you need sound insulation, vibration damping, insulation, or sealing materials, our EPDM closed-cell foam sponge is the dependable solution for your needs.
