4701-30-25021-04 polyurethane foam

4701-30-25021-04 PORON polyurethane foam materials have many outstanding properties, flame retardant, abrasion resistant, heat resistant, cold resistant, cushioning, sound absorbing, shock resistant, and sealing, such as excellent resistance to compression deformation, ultra-high resilience, impact resistance, and elasticity permanence. It can maintain its integrity and effectiveness in gap-filling, lining, and vibration isolation applications. It can meet the requirements of fixing and sealing smooth parts of various components and is suitable for non-structural fixing and sealing of light and small-shaped materials with excellent waterproof performance.

• Can be used in a variety of temperature ranges. It can be used from minus 40 degrees Celsius to 90 degrees Celsius.
• The surface has excellent wettability, easy to bond, easy to fabricate, and easy to punch and cut.
• Engineered polyurethane formulations offer a wide range of moduli to meet increased design flexibility requirements.
• Excellent sealing properties to avoid gas release and fogging.
• Anti-compression deformation, i.e., the elasticity is durable, which can ensure that the accessory gets long-term shockproof protection.
• Flame retardant, no harmful substances, no residue, no pollution of equipment, no corrosion of metal.

4701-30-25021-04  Polyurethane foam is widely used in new energy vehicles, electronic devices, and cushioning for aerospace and rail vehicle interiors. It has durability and reliability and is durable. Urethane foam has outstanding resilience, good vibration and impact absorption properties, and an excellent waterproof sealing effect. It has a wide range of hardness and thickness options and is easily compressed for applications requiring high flexibility.
