4790-79-09021-04P polyurethane foam

It can meet the requirements for fixing and sealing smooth parts of various components and is suitable for non-structural fixing and sealing of small and light-shaped materials with good waterproof performance.

• With excellent sealing, avoid gas release and atomization.
• Compressive deformation resistance, that is, the durability of elasticity, can ensure that the parts get long-term shock protection.
• It is flame retardant, does not contain harmful substances, does not remain, does not pollute equipment, and is not corrosive to metal.
• Can be used in a wide range of temperatures. It can be used from minus 40 degrees Celsius to 90 degrees Celsius.
• The surface has excellent infiltration, easy to bond, easy to make, and easy to cut.
• Engineering polyurethane formulations provide a wide modulus range to meet more design flexibility requirements

4790-79-09021-04P polyurethane foam is widely used for cushioning in new energy vehicles, electronic equipment, and aerospace and rail vehicle interiors. Durable and dependable, they are built to last. Polyurethane foam has outstanding resilience, good damping and impact absorption, 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.
