4790-92-12039-04P polyurethane foam

Rogers 4790-92-12039-04P polyurethane foam is ideally suited for applications where flexibility is particularly important. This foam maintains its integrity and effectiveness in gap-filling, sealing, and vibration isolation applications. 

4790-92-12039-04P Features

• 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.
• Soft and slow rebound: It is an extremely soft and slow rebound material with very low buckling force, which can slowly return to its original shape after being extruded by external force, providing good cushioning effect and suitable for occasions requiring soft touch and shock absorption performance.
• Strong resistance to compression and deformation: the elasticity is persistent, in long-term use or under certain pressure, it can still maintain a better shape and performance, which can provide long-term anti-vibration protection for the accessories and ensure their stability in the vibration or shock environment.
• Excellent sealing performance: it can effectively avoid gas outgassing and atomization, can fill the gaps and provide good sealing effect to prevent dust, moisture, etc. from entering the inside of the equipment, suitable for parts or components that need to be sealed.
• Wide temperature adaptability: it can be used in the temperature range of - 40℃ to 150℃, with good cold resistance and heat resistance, it can adapt to the requirements of use in different ambient temperatures to ensure that it can play a stable performance under various temperature conditions.
• Good chemical stability: flame retardant, does not contain harmful substances, no residue, will not contaminate the equipment, does not have corrosive to the metal, in line with the requirements of environmental protection, can be safely applied to a variety of fields, will not cause damage to the surrounding materials or the environment.
• Excellent processing performance: the surface has excellent wettability, easy to bond, easy to make, easy to punch, can be processed into a variety of shapes, sizes and thicknesses according to different needs, but also suitable for external coatings and other processing, as well as the customization of related products and stamping, to meet the diverse needs of different application scenarios.
