Polyurethane (PUR and PU) is a polymer composed of organic units joined by carbamate (urethane) links. While most polyurethanes are thermosetting polymers that do not melt when heated.
Temperature Range: -60 °C to 90 °C
➤ Wide Range of Hardness - The classification of hardness for polyurethane relies on the prepolymer's molecular structure and can be manufactured from 20 SHORE A to 85 SHORED
➤ High Load Bearing Capacity - Polyurethane has a high load capacity in both tension and compression
➤ Abrasion & Impact Resistance - For applications where severe wear prove challenging, polyurethanes are an ideal solution even at low temperatures.
➤ Resistance to Water, Oil & Grease - Polyurethane's material properties will remain stable (with minimal swelling) in water, oil and grease. Polyether compounds have the potential to last many years in subsea applications
➤ Strong Bonding Properties - Polyurethane bonds to a wide range of materials during the manufacturing process like plastics, metals and wood.
➤ Performance in Harsh Environments:
Polyurethane is very resistant to extreme temperature, meaning harsh environmental conditions and many chemicals rarely cause material degradation
➤ Mold, Mildew & Fungus Resistance:
Most polyether based polyurethanes do not support fungal, mold and mildew growth and are therefore highly suitable for tropical environments. Special additives can also be added to reduce this in polyester materials as well.
