Rigid polyurethane foam is a rigid foam material made of polyurethane through a specific process of foaming. This material is not only hard, but also has excellent resistance to permanent deformation in compression, which makes it effective in resisting external vibration and impact. Even at extreme temperatures, polyurethane rigid foam maintains its integrity and effectiveness, making it a cushioning material for gasket design, sound and heat insulation, and more.
There are many types of polyurethane foam, including soft polyurethane foam, flexible polyurethane foam, fast-rebound polyurethane foam, and rigid polyurethane foam. Each type of foam has its own unique properties and application scenarios, but rigid polyurethane foam is widely used in all types of precision products for shockproofing and other roles due to its excellent physical properties.
Main Characteristics
Excellent sealing to avoid gas release and atomization.
Resistance to compression and deformation, that is, the elasticity has durability, which can ensure that the accessories are protected by long-term anti-vibration.
Flame retardant, no harmful substances, no residue, no pollution of equipment, no corrosive to metal.
Can be used in a wide range of temperatures. From negative 40 degrees Celsius to 90 degrees range can be used.
The surface has excellent wettability, is easy to bond, easy to fabricate and easy to punch.
Engineered urethane formulations offer a wide modulus range - 2-90psi @ 25% deviation - to meet a wider range of design requirements.
