Tuftane® TPU Film Solutions
Permali manufactures a wide variety of Tuftane® branded thermoplastic polyurethane (TPU) elastomeric film products which are used in applications needing a tough, highly elastic flexible film as part of the product design.
Tuftane® TPU films are specified in many markets, applications and environments: from artificial heart components, blood plasma bags and isolation tents in hospitals, to construction pipelining, aircraft furnishings, automotive parts and industrial valves. Tuftane® TPU films in a choice of over 30 grades, supplied in rolls up to 1.6 m wide, slit to width.
Tuftane® TPU film grades are blended using either polyester or polyether aromatic PU polymer technologies. Standard and bespoke grades with specialty additives options are available to order. The Permali technical team works closely with customers to ensure that cost effective film material solutions are provided with the exact additives, technical specification and properties needed to meet their processing, product performance and regulatory requirements. Film grades from very soft and flexible to hard and stiff are blended to match end use applications.
All Tuftane® TPU films are blown film extruded in-house, supplied to manufacturers on a roll, slit to width and rewound to order to optimise material utilisation and minimise scrap.
