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
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.
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 commonly used foam/sponge rubber materials:
- Neoprene: Neoprene foam/sponge rubber typically 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, typically with 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), depending on the specific formulation.
