Abstract

Very small sized dielectric sleeving can be produced by stretching a length of larger sized tubing made of polyvinylidene fluoride. This material is available as electrical wire insulation. A length of insulation is stripped off the wire using conventional wire strippers. The original dimensions may be, for example, 9 mils internal diameter and 19 mils outside diameter. The length of insulation is held at both ends and pulled to four times its original length. The molecular structure of the material allows the molecules to rearrange themselves so that the material will stretch without breaking while reducing its internal diameter of the insulation to a little larger than 6 mils and the outside diameter to approximately 11 mils.

Method for Manufacturing Microminiature Dielectric Sleeving

Very small sized dielectric sleeving can be produced by stretching a length of larger sized tubing made of polyvinylidene fluoride. This material is available as electrical wire insulation. A length of insulation is stripped off the wire using conventional wire strippers. The original dimensions may be, for example, 9 mils internal diameter and 19 mils outside diameter. The length of insulation is held at both ends and pulled to four times its original length. The molecular structure of the material allows the molecules to rearrange themselves so that the material will stretch without breaking while reducing its internal diameter of the insulation to a little larger than 6 mils and the outside diameter to approximately 11 mils. The end result is a thin walled small diameter insulating sleeve that would not otherwise be produced efficiently.
