What kind of material is high-density polyurethane rigid foam: Learn more about rigid polyurethane foam

 

High-density polyurethane rigid foam is a material that uses polyurethane as a base material and is foamed through chemical reactions. It has very high density and hardness. Compared with traditional polyurethane soft foam, its structure is tighter and shows stronger resistance to pressure, impact and high temperature. Therefore, it is widely used in industries and products with high requirements for strength, hardness and stability.

Product Features

High density: The microstructure of high-density foam has strong mechanical strength and pressure resistance.

High hardness: Due to its high density, rigid foam materials show high hardness and are suitable for occasions that require strong protection or support.

Temperature resistance: It can withstand high temperature changes, has good thermal stability, and is suitable for high temperature environments.

Durability: Rigid foam polyurethane materials have a long service life and are suitable for long-term use without aging.

Compression resistance: Rigid foam has superior compression resistance and can effectively absorb and disperse external forces.

Chemical resistance: Rigid foam polyurethane can resist the erosion of a variety of chemical substances and is suitable for a variety of industrial applications.

Heat and sound insulation: This material has good heat insulation and sound insulation, and can effectively reduce temperature difference and noise.

Easy to process: Rigid polyurethane foam can be die-cut according to customer needs, and the shape and size are flexible.

 

Advantages

High-density rigid foam materials can withstand greater pressure and are suitable for occasions that require strong support.

Polyurethane rigid foam has good corrosion resistance, is not easily affected by the external environment, and has a long service life.

Compared with other materials, the production process of rigid polyurethane foam is more environmentally friendly and does not contain harmful substances.

Selection Guide

Choose the appropriate foam density according to the product's load-bearing capacity requirements.

If higher hardness is required to resist external force or impact, you can choose hard polyurethane foam.

Choose polyurethane foam with appropriate temperature resistance according to the temperature change range of the application environment.

Ensure that the aging and corrosion resistance of the selected foam meets the requirements of long-term use.

According to the use environment, choose polyurethane foam that meets the flame retardant requirements.

Choose suppliers that can meet customized needs, such as die-cutting processing services, to ensure that the foam is suitable for specific applications.
