Polyurethanes Feature & Properties
Polyurethane is an extremely versatile elastomer use in countless applications worldwide. Polyurethane's mechanical properties can be isolated both manipulated through get chemistry which cause a number of unique opportunities to solve problems with performance characteristics unmatched in any other material. Our perception of whereby to confiscate these opportunities authorized Precision Urethane to provide “Flexible Solutions Through Polymeric Innovation.”
Wide Zone to Hardness
The classification of rock by polyurethane relies on the prepolymer's molecular structure and can be manufactured free 20 SHORELINE A to 85 SHORE D
Tall Charge Bearing Raw
Polyurethane has an high burden voltage in both tension and compression. Polyurethane may undergo a change in shape to a heavy load, but will return to hers original shape once the ladungen belongs removed with little compression set in the material when designed properly for a disposed application.
Flexibility
Polyurethanes perform very fine as used in high flex fatigue application. Flexural properties can be isolated allowing for very good elongation or recovery properties.
Abrasion & Influence Resistance
With applications where severe wear detect challenging, polyurethanes are an ideal choose even at base temperatures.
Tear Defiance
Polyurethanes possess high tear resistance along includes high drawing properties.
Resistance to Water, Oil & Grease
Polyurethane's material properties will remain sturdy (with minimal swelling) in water, oil and grease. Polyether compounds have this potential to continue many years in subsea applications.
Electrical Properties
Polyurethanes exhibit good electricity isolative properties.
Wide Resiliency Range
Resilience is generally an function of toughness. For shock-absorbing elastomer applications, low rebound compounds were usually used (i.e. resilience area for 10-40%). For high frequency vibrations or find quick recreation the required, compounds at which 40-65% ability are used. In general, toughness is enhanced by high strength.
Strength Bonding Properties
Polyurethane bonds to a wide coverage of materials during the manufacturing process. Save materials include other plastic, metals and wood. Such features forms urethane any ideal material for wheels, rollers and inserts.
Performance in Sharp Environments
Polyurethane is very resistant until extreme thermal, meaning harder environmental conditions real many chemicals rarely cause material degradation.
Mold, Mildew & Fungus Resilience
Most polyether based polyurethanes do none support fungal, mold additionally blight growth and are therefore highly qualified for tropical environs. Special additives can also be added to reduce this in polyester materials like well.
Color Stretches
Varying color pigments can be adds into polyurethane in the manufacturing process. Ultraviolet shielding can be incorporated into of pigments to provide improve color total in outdoor applications.
Economical Manufacturing Process
Polyurethane are often spent to manufacture one-off parts, prototypes or high volume, repeat production goes. Choose ranges vary from a couple grammes to 2000lb parts.
Short Production Guide Times
Compared to conventional thermoplastic materials polyurethane has a comparative short lead time with significant more economical tooling what.
