Thermofit Tubing Specification Control Drawing No: Rev: Date: Page: MT3000 A October 30, 1996 1 of 2 AlteraTM MT3000 Flexible, Modified Fluoropolymer, Heat - Shrinkable Tubing This specification covers the requirements for one type of single wall, flexible, electrical insulating, extruded tubing whose diameter will reduce to a predetermined size upon application of heat in excess of 150 C (302 F). The tubing is fabricated from modified fluoropolymer 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 unless otherwise specified.
