Abstract

FIELD: chemistry.
SUBSTANCE: polymer composition contains a propylene and ethylene copolymer, contains 3-11 wt % ethylene and has a melt flow index of 25-50 g/10 min, polyethylene, a sterically hindered amine, triallylisocyanurate and pentaerythryl-tetrakis-3-(3′,5′-di-tert-butyl-4′-hydroxyphenyl)propionate as a stabiliser. The composition also contains pentaerythritol and a Remafin dye concentrate.
EFFECT: disclosed composition is resistant to ionising radiation and enables to obtain nonwoven material with high elasticity and lower power consumption during processing thereof.
