4790-79RL-20006-04PBLK Polyurethane foam

4790-79RL-20006-04PBLK microcellular structure polyurethane is a high-density soft microporous foam product with many outstanding properties, flame retardant, wear-resistant, heat-resistant, cold-resistant, cushioning, sound-absorbing, shockproof, sealing, such as excellent resistance to compression deformation, ultra-high resilience, impact resistance, elasticity persistence, etc. Is widely used in all kinds of precision products shockproof and other roles.

• 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.

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.
