FIELD: chemistry.
SUBSTANCE: method of making heat shrink tape for a gasket from polyethylene and an ethylene and vinyl acetate copolymer by mixing polyethylene and an ethylene and vinyl acetate copolymer with a sulphur-containing polyhydroquinone disulphide stabiliser with concentration of 0.1-0.3 wt %, irradiating the obtained tape with accelerated electrons with absorbed dose of 0.07-0.1 MGy and subsequent duplication at temperature of 145-150°C. The heat shrink tape is stretched by 15-70% at temperature of 140-150°C and cooled under a load to room temperature.
EFFECT: technologically improved process of making heat shrink tape.
