<p>elastomers, polymers. SUBSTANCE: invention relates to a method of covering elastomers, in part, ethylene-propylene copolymers and ethylene-propylene-diene terpolymers by easily separating material. Protective cover is applied as at least one layer. Protective material A comprising of material of increased volume is used a cover taken among: (i) branched or linear polyethylenes; (ii) copolymer of ethylene with vinyl acetate in the latter component content 2-18%; (iii) ionomeric resins; (iv) branched polypropylenes and corresponding mixtures. Invention ensures to cover elastomers efficiently and to separate off easily from their. EFFECT: improved method of covering, valuable properties. 7 cl, 1 tbl</p> |
