POLYMER COMPOSITIONS COMPRISING WASTE RUBBER AND/OR SCRAP LEATHER AS INGREDIENT

摘要

The invention relates to polymer compositions containing an ingredient and workable by processing methods of thermoplastics. The essence of the composition of the invention is that it contains as ingredient 10-70 % by mass of crushed waste rubber of preferably 2-5 mm grain size and/or shredded leather fibres, as well as one or more tensides, and, if desired, additives or auxiliaries corresponding to the field of application, such as fire retardants, blowing agents, moisture-binding agents, traditional fillers, colouring agents and pigments, lubricants and stabilizers, crosslinking agents.
