Abstract

Fremgangsmåte for resirkulering av rester/avfall av elas- tomermaterialer på basis av polyetylen, eller på basis av kopolymerer av etylen og en annen olefinmonomer, fornettet med silan. Oppfinnelsen muliggjør resirkulering av rester/avfall av elastomermaterialer på basis av polyetylen, eller på basis av kopolymerer av etylen og en annen olefinmonomer, fornettet med silan, med henblikk på fremstilling av regenererte elas- tomermaterialer, særlig egnet for overtrekning av elektriske kabler. For den fornyede anvendelse tilsettes restene/avfallet før varmknaingenjdicykloheksylkarbodiimid eller et polydicyk- loheksylkarbodiimid i vektforhold 0,5 % til 5 % beregnet på vekten av elastomermaterialet.Process for recycling residues / waste of elastomeric materials based on polyethylene, or on the basis of copolymers of ethylene and another olefin monomer crosslinked with silane. The invention enables recycling of residues / waste of elastomeric materials based on polyethylene, or on the basis of copolymers of ethylene and another olefin monomer, crosslinked with silane, for the production of regenerated elastomeric materials, particularly suitable for coating electric cables. For the renewed use, the residues / waste are added before hot-nucleated dicyclohexylcarbodiimide or a polydicyclohexylcarbodiimide in weight ratio 0.5% to 5% by weight of the elastomeric material.
