MicroFit Small diameter, high shrink ratio, heat-shrinkable tubing MicroFit tubing is micro-sized, heat- Yet, upon heating, the same tubing low-outgassing materials. MTI000 tubing may shrinkable tubing that offers a high shrink shrinks to fit tightly on a wide range of be sterilized by radiation, ethylene oxide, ratio (up to 3:1) and fits a range of diameters substrate diameters. steam, and dry heat with no significant from .007 to .045. It is offered in a variety of change in physical properties. materials including two medical-grade MicroFit tubing is offered in three materials: formulations from our Altera line of medical- RW-175, MT1000, and MT2000. MT1000 MT2000 tubing is made from a tough, grade, heat-shrinkable tubing products. and MT2000 meet the requirements of modified polyolefin that offers flexibility, U.S. Pharmacopeia (USP) Class VI. lubricity, and good electrical insulation MicroFit tubing provides electrical insulation, performance. MT2000s low shrink temperature mechanical protection, and strain relief in the RW-175 and MT1000 tubings utilize a tough enables the tubing to shrink faster than other smaller, more compact medical devices and semirigid fluoropolymer. They are especially materials with similar attributes, thereby commercial electronics products suitable for applications requiring high- reducing the risk of damage to temperature- manufactured today. MicroFit tubings temperature performance, outstanding sensitive substrates. MT2000 tubing may high shrink ratio eases installation since resistance to abrasion and cut-through, be sterilized by gamma radiation or the tubings diameter is large enough to slide and excellent resistance to a variety of fluids. ethylene oxide with no significant change easily over the micro-sized substrate.
