Polyurethane foam is the material we use to make our garage column protectors . It is a very used material due to its special properties. Let's see more carefully what are the physical properties of polyurethane foam .
Physical properties of polyurethane foam
Polyurethane is an extremely versatile elastomer that is used in countless applications throughout the world. There are many properties of polyurethane foam based on its molecular structure.

High load capacity
The polyurethane foam has a high load capacity both in tension and in compression. The polyurethane can change shape under a heavy load, but will return to its original shape once the load is removed.
Flexibility
Polyurethane foam works very well when used in applications of high bending fatigue. The flexural properties can be isolated allowing a very good capacity of elongation and recovery.
Resistance to abrasion and impact
Due to this property, polyurethane foam is very useful in applications where severe wear occurs, even at low temperatures. A very useful capaxity in garage protection .
Resistance to water, grease and gasoline
The properties of polyurethane foam remain intact (with minimal swelling) if immersed in water / oil or grease. Therefore, polyether compounds last for many years in underwater applications.
Production facilities
Compared to conventional thermoplastic materials, polyurethane has a relatively short manufacturing time, and tool costs are significantly cheaper.
Color range
Different color pigments can be added to the polyurethane during its manufacturing process.
Resistance to mold and mildew
Most polyurethanes based on poly ether are not compatible with the growth of fungi or mold and therefore are very suitable for tropical environments.
Resistance to hostile conditions
Polyurethane is very resistant to extreme temperatures, that is, to harsh environmental conditions. Likewise, many chemicals will not cause material degradation.
Electrical properties
The polyurethane foam has good electrical insulation properties.
These are the most remarkable physical properties of polyurethane foam , which provide some remarkable advantages over conventional materials such as rubber, metal or plastic.
