FIELD: chemistry.
SUBSTANCE: tube is made from a polyolefin composition which contains a (co)polymer of ethylene or (co)polymer of propylene, a vitamin E type stabiliser of formula
(I) , where R1, R2, R3, R4 and R5 independently denote H or unsubstituted or substituted aliphatic or aromatic hydrocarbon radicals which may contain heteroatoms, and a phenol stabiliser of formula
(II); in which R6, R7 and R8 independently denote unsubstituted or substituted aliphatic or aromatic hydrocarbon radicals which may contain OH groups; and X1, X2 and X3 independently denote H or an OH group, provided that at least one of X1, X2 and X3 denote an OH group, and optionally an ultraviolet stabiliser.
EFFECT: low emission of additives and products of decomposition thereof in water.
