Abstract
Heat shrinkable tubing is disclosed which provides cushioning and vibration damping particularly useful for hand held power driven equipment. The tubing is extruded with internal ridges running along its entire length, which when heat shrunk on a substrate provides air pockets for cushioning and vibration damping. Embodiments disclosed include multiple layers of such material and multiple layers with smooth and texturized layers extruded concentrically on the primary vibration damping layers.
Claims8
Heat shrinkable tubing comprising an interior and exterior layer of tubular polymeric material concentrically extruded one on the other, the tubing having radial shrinkage memory and longitudinal shrinkage memory, the interior tubular polymeric material having substantially parallel raised portions along its entire interior length, such heat shrinkable article capable of shrinking in response to heat in uniform fashion to provide areas of cushioning and vibration damping after application to a substrate.
A method of forming a cushioned, vibration damping surface on a substrate comprising placing a heat shrinkable tubing on the substrate, applying heat to the tubing causing the tubing to shrink both radially and linearally on the substrate wherein the heat shrinkable tubing comprises an interior and exterior layer of tubular polymeric material concentrically extruded one on the other, the tubing having radial shrinkage memory and longitudinal shrinkage memory, the interior tubular polymeric material having substantially parallel raised portions along its entire interior length, such heat shrinkable article shrinking in response to the heat in uniform fashion to provide areas of cushioning and vibration damping after application to the substrate.
