Duponts Hytrel TPC Advances Sustainable Material Innovation

Traditional rubber materials often face challenges with aging and brittleness in harsh environments, while conventional plastics limit design possibilities. Hytrel® TPC emerges as a groundbreaking thermoplastic copolyester elastomer that combines exceptional flexibility with stable mechanical properties across wide temperature ranges, unlocking new potential for innovative designs across industries.

Developed by Covestro, Hytrel® TPC demonstrates remarkable durability that outperforms conventional rubber, maintaining its integrity through repeated multidirectional flexing. This exceptional resilience makes it indispensable for automotive applications such as constant-velocity joint (CVJ) boots that must withstand extreme temperature variations and demanding operating conditions.

The material's superior elasticity and wear resistance have also made it valuable in performance footwear and athletic apparel, providing unmatched comfort and support. Its excellent resistance to oils, fuels, and other chemicals further establishes it as an ideal choice for cosmetic packaging and consumer electronics, ensuring product quality in diverse environments.

Hytrel® TPC offers manufacturers exceptional processing flexibility through various cost-effective molding techniques including injection molding, blow molding, and rotational molding. This adaptability makes it suitable for applications ranging from nonwovens to wire and cable sheathing. Covestro provides multiple Hytrel® TPC grades with different combinations of flexibility, mechanical properties, and other key characteristics, enabling highly customized solutions for specific requirements.

• Automotive: CVJ boots, air ducts, seals, fenders, and vibration dampers benefit from its exceptional wear resistance, oil resistance, and temperature stability.
• Sports & Leisure: Athletic shoes, ski boots, bicycle grips, and outdoor apparel leverage its flexibility, elasticity, and durability.
• Consumer Goods: Smartphone cases, headphone cables, power tool handles, and household items utilize its pleasant tactile qualities and design versatility.
• Medical: Catheters, IV tubes, and seals benefit from its biocompatibility and reliable physical properties.
• Industrial: Wire/cable sheathing, industrial hoses, gaskets, and conveyor belts maintain performance in demanding environments.

Covestro's commitment to sustainability materializes in Hytrel® TPC ECO-B, which incorporates up to 72% second-generation biomass content certified under ISCC+ standards. This biomass-balanced approach maintains identical performance to petroleum-based versions while supporting the transition to circular economy principles. The Hytrel® TPC RS series further expands sustainable options with independently verified bio-based content.
