With single or bilateral coating and highly abrasion-resistant: HEYflex fabrics are perfect for all types of bellows. Whether two train wagons have to be connected or a lifting platform must be covered – the polyester fabrics with different coatings (PVC, PUR, TPU) are UV resistant, resistant to chemicals, flame retardant and perfectly suitable for the most diverse requirements with grammages between 300 and 750 g/m² and thicknesses between 0.20 to 0.71 mm.

A perfect combination: “Bellow hybrid” was developed for kink resistant and abrasion proof bellows with excellent media resistance. The combination of a PU coating on the exposed side and a PVC coating on the back ensures a material with material properties perfectly customized to the respective application.
