Thermoplastic polyurethane, or TPU, is a versatile polymer that bridges the gap between rubber and rigid plastic. It combines the elasticity of rubber with the strength and processability of a thermoplastic, so it can be melted, shaped and recycled while still resisting abrasion, oils and tearing. Those properties make it a popular choice for films, coatings and moulded parts. Permali processes TPU into Tuftane film by blown film extrusion at its own site.
