TPU extrudes into some of the most demanding flexible products in industry. It holds up where plasticized PVC and rubber fall short: abrasion resistance that survives drag and flex, kink recovery in tubing, and toughness in thin film.
Air lines, coiled cords, fuel and lubrication lines, and protective conduit that need abrasion resistance and kink recovery.
Blown and cast film for breathable membranes, protective and laminating films, and technical sheet.
Custom profile, edge trim, and tight-tolerance tubing where flex life and surface finish matter.
Abrasion-resistant jacketing over cable, hose, and rope, including retractile cords.
Three variables drive the grade choice:
Polyester for the best abrasion and oil resistance (most hose and tube); polyether for cold flexibility and hydrolysis resistance (wet or cold lines).
Softer grades for flexible tube and film, harder grades for structural profile and jacketing. Extrusion grades commonly sit around Shore A 85 to 95.
Extrusion grades are formulated for melt strength and draw-down so the profile holds shape through the die and cooling. We will point you to the right grade for your line.
For the chemistry trade-offs, see polyester vs polyether TPU.
TPU is hygroscopic, so it must be dried with a desiccant dryer before extrusion. Skipping this step shows up as bubbles, voids, and reduced strength in the product. Each grade's Technical Data Sheet gives the recommended drying and processing conditions.
Regrind handling, screw design, and die temperatures all affect surface finish on TPU. Our technical team can talk through the setup, and the manufacturer's processing guides are available for the grades we supply.
Technical Data Sheets and Safety Data Sheets are available for every grade, with food-contact statements (FDA 21 CFR 177.2600) for select grades on request. We hold inventory in North American warehouses and ship across the US, Canada, and Mexico, with samples usually out the same business day. Cross-references from other TPU extrusion grades are available on request.
