Polyurethane foam what material？

Polyurethane foam is made of isocyanate and polyether as the main raw materials. Under the action of various additives such as foaming agent, catalyst, flame retardant, etc., it is mixed with special equipment and foamed on site by high-pressure spraying. . Polyurethane foam has two types: soft foam and rigid foam. Soft foam has an open-cell structure, while rigid foam has a closed-cell structure. Soft foam is divided into two types: skinning and non-skinning.

 

Polyurethane rigid foam is a new type of synthetic material with thermal insulation and waterproof functions. The main function of flexible polyurethane foam is to cushion. Polyurethane flexible foam is often used in electronic equipment manufacturers and new energy industries. For example: rigid support of structural components, filling of design gaps, protective gaskets for sensitive components and acoustic linings.

 

Use

• High efficiency and energy saving, no gaps after filling, and strong bonding after curing.

•Shockproof and compressive, no cracking, no corrosion, no falling off after curing.

• With ultra-low temperature thermal conductivity, heat-resistant heat preservation.

• Efficient insulation, sound insulation, waterproof and moisture-proof.

 

Application

•Mobile phone speakers, power modules, lampshade seals, automobiles, electronic equipment and computer communication equipment and other industries

• Fixed bonding and protection of electronic products, cameras, speakers, LCD monitors, signs, etc.

• Batteries, with plug-in compression foam

• Computer, electronic equipment feet, etc.
