What is Polyurethane Foam and Silicone Foam?

 

Polyurethane foam

When it comes to polyurethane foam, it's easy to overlook or completely miss the vast array of products that polyurethane foam involves. From mattress sofas to electronic equipment manufacturers and new energy industries, the applications of polyurethane foam in life are almost endless. Polyurethane foams come in different levels of viscosity and strength.

Silicone foam application

Silicone foam also comes in varying degrees of thickness, strength and firmness. Although silicone foams are not as common as polyurethane foams, they are still widely used in applications such as gaskets, insulation and vibration reduction.

 

Where are silicone foam and polyurethane foam used?

Foam is widely used in many industries around the world, for electronic equipment manufacturers, the new energy industry and the railway market. Such as: kitchen and bathroom appliances; auto parts; cable, pipe and house insulation; building sealants and fire protection; gasket sealants; and vibration damping. Insulation is a particularly important use for foam, as it plays a key role in reducing carbon dioxide emissions, thereby reducing human impact on global warming.

 

Silicone foam advantages

Silicone foam has excellent versatility, and silicone foam is ideal for gaskets, insulation, sealing and vibration damping, especially in applications where the sealing surface is not smooth and the temperature varies widely. Here, we explore the unique benefits of a range of silicone foams:

 

Advantages of silicone foam

• Silicone foam has open-cell or closed-cell foam construction

  The open-cell foam construction allows for high absorption of water, moisture and dust - making it ideal for typical sponges used in car washes.

  The closed-cell foam construction cannot absorb water, moisture or dust, making it ideal for sealing applications requiring water and dust. This type is inherently hydrophobic (repels water).

• Low flammability - can be used for fire protection and glass sealing (UL94 rating)

• Low density - reduces overall weight and improves dimensional stability

• Excellent resistance to compression set - fast rebound to original thickness

• Mechanical properties remain virtually unchanged from -60°C to 230°C

• Full flexibility over a wide temperature range

• Good sound and thermal insulation

• High resistance to harsh chemicals and UV light - excellent weather resistance

• No toxic chemicals are released during thermal decomposition

• Excellent dielectric properties - can be used to electrically insulate or conduct electricity

 

Polyurethane foam application

Polyurethane foam is very suitable for electronic equipment manufacturers, new energy industry and railway markets. It's a durable and inexpensive material, although when broken down easily releases harmful chemicals that can irritate breathing. Here, we explore the unique benefits of a range of polyurethane foams:

 

The advantages of polyurethane foam

• Polyurethane is harder than rubber, more flexible than plastic, has high strength and impact resistance

• Excellent abrasion resistance

• Extremely light, helps reduce emissions in transportation applications

• Highly resistant to harsh chemicals and oils

• One of the softest foams available in the electronics industry

• Excellent shock resistance due to high vibration frequency
