Thermofit Tubing Specification Control Drawing No: Rev: Date: Page: MT2000 B May 14, 1999 1 of 2 AlteraTM MT2000 Modified, Medical Grade, Polyolefin, Heat - Shrinkable Tubing This specification covers the requirements for one type of single wall, electrical insulating, extruded tubing whose diameter will reduce to a predetermined size upon application of heat in excess of 140C (284F). The tubing is fabricated from modified polyolefin crosslinked by irradiation. It shall be homogenous and essentially free from flaws, defects, pinholes, seams, cracks or inclusions. The tubing is fabricated from materials which meet the requirements of U.S. Pharmacopeia Class VI Plastics. Color shall be black or clear unless otherwise specified.
