Huntsman TPU

Thermoplastic polyurethanes (TPUs) offer exciting possibilities for meeting the manufacturing challenges of a fast-changing world. Well-known for their outstanding versatility, Huntsman's TPUs can improve the production and enrich the performance of anything from shoes, seals and films to filters, conveyor belts and cables.
Building on years of experience, we have developed a large number of TPUs with limitless potential to meet adhesive, coating, injection molding, extrusion, film and compounding application requirements.
  • Innovative solutions that can be customized to individual needs
  • Ideally suited to a wide range of processing technologies
  • Global supply chain plus excellent technical support



From Wikipedia, the free encyclopedia

Example of synthesis of a polyurethane. Note the urethane groups -NH-(C=O)-O- linking the units of the product.
polyurethane (IUPAC abbreviation PUR, but commonly abbreviatedPU) is any polymer consisting of a chain of organic units joined byurethane (carbamate) links. Polyurethane polymers are formed throughstep-growth polymerization by reacting a monomer containing at least twoisocyanate functional groups with another monomer containing at least two hydroxyl (alcohol) groups in the presence of a catalyst.
Polyurethanes are widely used in high resiliency flexible foam seating, rigid foam insulation panels, microcellular foam seals and gaskets, durable elastomeric wheels and tires, automotive suspension bushings, electrical potting compounds, high performance adhesives and sealants, Spandex fibers, seals, gaskets, carpet underlay, and hard plastic parts (such as for electronic instruments).
Polyurethane products are often called "urethanes". They should not be confused with the specific substance urethane, also known as ethyl carbamate. Polyurethanes are neither produced from ethyl carbamate, nor do they contain it.
