Tube material

in biopharmaceutical productions needs to meet specific requirements. It must be resistant to heat and chemicals and possess suitable characteristics concerning elasticity, abrasiveness, gas permeability, color, density, mechanical stability, light sensitivity and rigidity. At the present time, five different tube materials are available: 1) thermoplastic elastomers (low cleavability, high weldability, low gas permeability) 2) platin-hardened silicon (flexible, temperature resistant, no leachables, low-priced) 3) peroxide-hardened silicon (good biocompatibility, no leachables) 4) modified polyolefin (high purity, chemical resistance, high pressure resistance) and 5) modified polyvinyl chloride (broad chemical resistance and enduring flexibility). The thermoplastic elastomers are preferred for biopharmaceutical productions ⁶⁷.
