describe:
Polyurethane foam is a polymer material. Foam is divided into PU foam, anti-static foam, conductive foam, EPE, anti-static EPE, PORON, CR, EVA, bridging PE, SBR, EPDM, etc. Polyurethane foam is suitable for caulking, gasketing and sealing applications
What is polyurethane foam and where is it used?
Foam is divided into PU foam, anti-static foam, conductive foam, EPE, anti-static EPE, PORON, CR, EVA, bridging PE, SBR, EPDM, etc. PU is polyurethane, and PU skin is the skin of the polyurethane component. Widely used in electronic equipment manufacturers, new energy industry and railway market.
Polyurethane foam:
Polyurethane foam is a polymer material, PU is polyurethane, and polyurethane is a new organic polymer material, known as the "fifth largest plastic", and is widely used in many fields of the national economy because of its excellent performance.

General advantages of polyurethane foam materials: non-toxic and harmless
Wide range of hardness (Shore A15~Shore D90) under the same hardness, higher bearing capacity than other elastomers, high wear resistance, high impact resistance Stable moisture vapor transmission at 140°C - suitable for microporous materials Unaffected by ozone radiation resistance Can be made into flame retardant material High mold resistance and low friction Can be processed on standard equipment Can adhere to wood, metal and most plastics The joint can be made into a noise-reducing material with low molding and processing costs and is widely resistant to oils, greases and chemicals.
Rigid polyurethane foam material is rigid and has excellent compression set resistance to ensure long-term stability in caulking, gasketing and sealing applications.
Polyurethane foam can provide rigid support for design gaps, ensure the physical position of related components, and provide designers with convenient and flexible structural auxiliary materials. At the same time, it can provide protection during the transportation of sensitive and fragile devices to prevent the devices from being damaged by pressure.
Rigid polyurethane foam material maintains integrity and effectiveness even after prolonged exposure to changing temperatures. Ideal for use in potentially extreme environments. Various applications including heat, vibration, dust, dirt and vibration.
