Foam/Sponge Rubber Extrusion

Foam/sponge rubber extrusion refers to manufacturing foam or sponge rubber profiles through extrusion. It is categorized as open-cell sponge rubber extrusion and closed-cell sponge rubber extrusion. It has the following superior advantages to other rubber extrusions.

  • Excellent sealing and insulation properties
  • Highly durable and flexible
  • Exceptional resistance to chemicals and moisture
  • Excellent weathering, ozone, and UV resistance
  • Shock absorption and cushioning capabilities
  • Cost-effective production

Key Features of Foam/Sponge Rubber Extrusion

Cellular Structure

Foam/sponge rubber extrusion creates a cellular structure with interconnected air or gas-filled cells. It can provide cushioning, flexibility, and compressibility.

Customizable Density And Hardness

The density and hardness of foam/sponge rubber profiles can be tailored to meet specific application requirements.

Excellent Compression And Recovery

Foam/sponge rubber exhibits excellent compression and recovery properties. So it can compress under pressure and quickly regain its original shape after release.

Thermal And Acoustic Insulation

Foam/sponge rubber profiles offer inherent thermal and acoustic insulation properties. It can reduce heat transfer and sound transmission.

Flexibility And Conformability

Foam/sponge rubber profiles are highly flexible and conform to irregular surfaces or contours. It can ensure proper fit and sealing.

Resistance to Moisture And Chemicals

Foam/sponge rubber exhibits resistance to moisture, water absorption, and certain chemicals. It is suitable for humid or wet environments and contact with certain substances.

Applications of Foam/Sponge Rubber Extrusion

The foam or sponge rubber profiles suit various. Industries and applications, including automotive, construction, HVAC, electronics, packaging, and more. They are used for sealing applications (gaskets and weatherstripping), insulation, cushioning, soundproofing, shock absorption, and vibration dampening.

FAQs

Foam/sponge rubber extrusions are commonly made of neoprene, EPDM (ethylene propylene diene monomer), silicone, and polyurethane. When selecting the material, it depends on the properties. Such as density, hardness, temperature, and chemical resistance.

The working temperature of foam/sponge rubber extrusion depends on the specific type of rubber material used in the manufacturing process. Here are the approximate working temperature ranges for some used foam/sponge rubber materials:

  • Neoprene: Neoprene foam/sponge rubber has a working temperature range of -40°C to +120°C (-40°F to +248°F).
  • EPDM: EPDM foam/sponge rubber has a broader operating temperature range of approximately -40°C to +150°C (-40°F to +302°F).
  • Silicone: Silicone foam/sponge rubber is known for its high-temperature resistance. It has a working temperature range of -60°C to +230°C (-76°F to +446°F).
  • Polyurethane: Polyurethane foam/sponge rubber can have a working temperature range of -40°C to +80°C (-40°F to +176°F). It depends on the specific formulation.
