ETERNALAST® TPU is a series of high performance thermoplastic polycarbonate-based polyurethanes, developed to provide exceptional durability, mechanical strength, and environmental stability. Its advanced formulation makes it ideal for extrusion applications, including technical films, inner tubes, wire coatings, and pneumatic tubing, where reliability and long-term performance are crucial.
One of its most significant advantages is superior resistance to heat, chemicals, hydrolysis, and weathering, outperforming traditional polyester- and polyether-based TPUs. Extensive testing confirms that ETERNALAST® polycarbonate-based TPUs maintain their integrity even under extreme conditions, such as 120 ºC heat exposure for 50 days, chemical immersion at 100 ºC for 30 days, and simulated climate chamber testing for 1,200 hours.
For technical films, ETERNALAST® polycarbonate-based TPUs exhibit extraordinary tear resistance, surpassing common materials such as PA6, PA12, and LDPE, making it highly effective for packaging and industrial applications. In inner tubes for bicycles, ETERNALAST® delivers exceptional puncture resistance, nearly twice as strong as standard TPUs, significantly improving durability and safety.
When used in wire and cable coatings, ETERNALAST® polycarbonate-based TPU are halogen-free and flame-retardant, exceeding UL 1581 standards. They retain mechanical performance even after prolonged exposure to heat, oil, and water, ensuring long-term reliability. In pneumatic tubes, multilayer designs enhance burst resistance, complying with ISO 7628 and SAE J2260 standards, they offer superior pressure handling and impact resistance.
With its exceptional performance and versatility, ETERNALAST® polycarbonate-based TPU are the ideal choice for manufacturers looking for durable and high-performance materials.
