Opaque black material between, 0,25 and 0,4 mm. thick.

Rigid PVC supports in each fold, which are welded to the polyamide fabric on high frequency machines. These rigid supports come in thicknesses of 0.8 mm. in white, 1 and 1,5 mm. in grey. For specific cases, TECNIFUELLE bellows may include polyurethane slides joined to the rigid PVC framework to prevent unwanted noise and improve internal sliding.
