Foam Seal

Foam seal refers to continuously extruded rubber profiles with a cellular, sponge-like structure that deliver exceptional lightness, high compressibility, and superior cushioning properties. They are classified into two main categories based on cell morphology:

  • Open-Cell Sponge Rubber Extrusion – interconnected cells providing breathability, excellent sound absorption, and vibration damping.
  • Closed-Cell Sponge Rubber Extrusion – fully independent sealed cells enabling genuine water and dust resistance (up to IP68), making it the material of choice for critical sealing in EV battery enclosures, automotive doors and sunroofs, outdoor electrical cabinets, rail vehicles, and cleanroom applications.

Key Features of Foam Rubber Extrusion

Cellular Structure

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

custom density sponge rubber extrusion profiles

Customizable Density And Hardness

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

Excellent Compression And Recovery

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

Flexibility And Conformability

Foam 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 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 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 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 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 rubber materials:

  • Neoprene: Neoprene foam rubber has a working temperature range of -40°C to +120°C (-40°F to +248°F).
  • EPDM: EPDM foam rubber has a broader operating temperature range of approximately -40°C to +150°C (-40°F to +302°F).
  • Silicone: Silicone foam 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 rubber can have a working temperature range of -40°C to +80°C (-40°F to +176°F). It depends on the specific formulation.
