Polyurethane products often are called “urethanes”, they 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, rigid foam insulation panels, microcellular foam seals and gaskets, durable elastomeric wheels and tires (such as roller coaster, escalator and skateboard wheels), automotive suspension bushings, high-performance adhesives, surface coatings, surface sealants, and hoses.
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
Super Abrasion Resistant Urethane (Vulkollan®)- 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.
Abrasion-Resistant 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.
Heat Resistant Urethane– This urethane material has greater heat resistance up to 120°C (general urethane withstands up to up to 70°C). Suitable for use in applications where high mechanical strength is required in high-temperature range, such as work receiver for hot air dryer.
Low Repulsion Urethane– This urethane offers more resistance to compression than normal urethane making it hard to deform, it excels in shock absorption. Due to its tensile strength and elongation being weaker than other urethanes of the same hardness it is not recommended for the absorption of large impact energy.
Extra Low Hardness Urethane– This urethane has a high physical strength that cannot be obtained from conventional soft materials, it is highly resistant to impact and has little compression.
Shock Absorbing Gel– An extremely soft gel with Asker F hardness. Being a urethane-based synthetic rubber, it has high material strength offering a major characteristic of three-dimensional slow recovery – the function to recover after compression slowly and in multiple directions.
