Ski Tip Fill material. Made of UHMW (P-tex) base material that is 1.2mm thick. It is sanded and flamed on both sides. This is actually the ptex base!
You should joint the 2 pcs of base 1.2mm + 1.2mm = 2.4mm, with epoxy, to get 2.4mm.
Base material works just as good as tip fill. It is proven. Just remember to put epoxy in between the layers.
sanded and flamed to give the best adhesion with epoxy.
