    Advantages of Polyurethane?

    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.

    Strong Bonding Properties
    Polyurethane bonds to a wide range of materials during the manufacturing process. These materials include other plastics, metals, and wood. This property makes polyurethane an ideal material for wheels, rollers, and inserts.

    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.

    Economical Manufacturing Process
    Polyurethane is often used to manufacture one-off parts, prototypes or high volume, repeat production runs. Size ranges vary from a couple grams to 2000lb parts.

    Short Production Lead Times
    Compared to conventional thermoplastic materials polyurethane has a relatively short lead time with significantly more economical tooling costs.
