Wide Range of Hardness
The classification of hardness for polyurethane relies on the prepolymer's molecular structure can be manufactured from 20 SHORE A to 85 SHORE D

High Load Bearing Capacity
Polyurethane has a high load capacity in both tension and compression. Polyurethane may undergo a change in shape under a heavy load, but will return to its original shape once the load is removed with little compression set in the material when designed properly for a given application.

Polyurethanes perform very well when used in high flex fatigue applications. Flexural properties can be isolated allowing for very good elongation and recovery properties.

Abrasion & Impact Resistance
For applications where severe wear prove challenging, polyurethanes are an ideal solution even at low temperatures.

Tear Resistance
Polyurethanes possess high tear resistance along with high tensile properties.

Resistance to Water, Oil & Grease
Polyurethane's material properties will remain stable (with minimal swelling) in water / oil / grease. Polyether compounds will last many years in subsea applications.

Electrical Properties
Polyurethanes exhibit good electrical insulating properties.

Wide Resiliency Range
Resilience is generally a function of hardness. For shock-absorbing elastomer applications, low rebound compounds are usually used i.e. resilience range of 10-40%. For high frequency vibrations or where quick recovery is required, compounds in the 40-65% resilience are used. In general, toughness is enhanced by high resilience.

Performance in Harsh Environments
Polyurethane is very resistant to temperature extremes, meaning harsh environmental conditions and many chemicals will not cause material degradation.

Mold, Mildew & Fungus Resistance
Most polyether based polyurethanes do not support fungal / mold / mildew growth and are therefore highly suitable for tropical environments and FDA applications. Special additives can also be added to reduce this in polyester materials as well.

Color Ranges
Varying color pigments can be added to polyurethane in the manufacturing process. Ultraviolet shielding can be incorporated into the pigment to provide better color stability in outdoor applications.
