Polyurethane products often called “urethanes”, are an extremely diverse product due to the multiple ways it can be configured during manufacturing. This material can be used in the manufacturing of flexible, high-resilience foam seating and rigid foam insulation panels. Urethane is also used in the manufacturing of microcellular foam seals and gaskets, durable elastomeric wheels and tires (roller coaster, escalator and skateboard wheels), automotive suspension bushings, high-performance adhesives, surface coatings, surface sealants and hoses.

TYPES OF URETHANE RUBBERS:
Ether Polyurethane- Excels in mechanical strength, offering high impact resilience and superior water resistance compared to Ester Polyurethane but has low heat resistance and chemical resistance.
Ester Polyurethane- Excels in mechanical strength offering 30～100% more mechanical strength than Ether Polyurethane with superior oil resistance. This rubber has low heat resistance, chemical resistance and low impact resilience.
Conversion Note: (70°C converts to 158°F. -40°C converts to -40°F. -20°C converts to -4°F).
SUPER ABRASION-RESISTANT URETHANE
A super abrasion resistant urethane which is far superior to conventional urethanes in abrasion resistance and load bearing. It is 6 times stronger in abrasion resistance and 1.5 times stronger in mechanical strength compared to the standard urethane.
Offering unique composition results in abrasion resistance that is 2.5 times higher than general urethane this material is a lower cost than Vulkollan® but offers the same attributes but to a lesser degree.
