FIELD: chemistry.
SUBSTANCE: invention relates to biopharmaceutical tube and product, including such tube. Flexible tube is made of mixture of polyolefin and block-copolymer based on styrene and plasticiser. Styrene-based block copolymer has configuration of blocks A-B-A and molecular weight at least about 350 kg/mol. Polyolefin and styrene-based block-copolymer are present in ratio about 1.2:1 to about 0.2:1.
EFFECT: manufacturing biopharmaceutical flexible tubes and products containing them, possessing improved operating characteristics of pumping.
