FIELD: chemistry. ^ SUBSTANCE: propylene polymer composition contains a homo- or copolymer of propylene and an elastomeric component. The elastomeric component is hydrocarbon rubber selected from a group consisting of ethylene propylene rubber, ethylene propylene diene rubber and ethylene propylene norbornadiene rubber. The tube has peel strength of 300-700 N/cm before impact and 150-450 N/cm after impact, measured in accordance with DIN 30678. ^ EFFECT: disclosed tube has considerably high resistance to impact loads at low temperatures, and peel strength before and after impact is sharply improved compared to ordinary tubes coated using ordinary adhesive layers. ^ 11 cl, 2 tbl |
