High frequency-weldable panels and sheeting comprise reticulated foams into which uniformly distributed high frequency-weldable plastic powder (I) has been introduced and fixed by means of a finely divided powder having hot melt-adhesive properties. Mfr. is effected either by first dusting the web system in the reticulated foam uniformly with the finely divided powder having hot melt adhesive properties and then uniformly introducing the (I), or uniformly introducing into the foam, if appropriate with heating, a (I) which has been uniformly dusted with a finely divided powder having hot melt-adhesive properties. The panels and sheeting of foams esp. reticulated soft polyurethane foams, can be employed in any thickness and are easily handled and usuable. They are useful for cushioning and can, during fabrication, be welded to any other material used in cushioning. Uses include upholstering of furniture and car seats, mattresses, loose cushions etc. |
