Zusammenfassung: | FIELD: chemistry. ^ SUBSTANCE: thermoplastic elastomeric composition contains polypropylene, polyethylene, triple ethylene-propylene-diene copolymer, sulfur, primary and secondary vulcanisation accelerators, stearic acid and zinc oxide. Rubber crumb and bitumen are introduced into composition additionally. Combination of components in definite ratio improves rheological properties of composition and, correspondingly its processability. ^ EFFECT: high-strength products, of high ozone and atmosphere stability, resistance, can be practically fully utilised after expiry of product life. ^ 5 cl, 2 tbl, 6 ex |
