4790-92-25021-04P Polyurethane foam Features

4790-92-25021-04P Rogers polyurethane foam is ideal for applications where flexibility is especially important. It maintains its integrity and effectiveness in gap-filling, gasketing and vibration isolation applications. It meets the requirements of fixing and sealing in smooth areas of various components and is suitable for non-structural fixing and sealing of lightweight and small-shaped materials, with excellent waterproofing properties.

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
