Silicone Tube Dilation
Silicone tubing is used throughout the medical industry as it is synthetically derived and inert against various fluids. To aid in the attachment of this tubing to ports or valves, the tubing is exposed to solvent vapors causing the tubing to dilate. As the solvent flashes off, the tubing contracts back to its original configuration. It is import to choose a solvent that will not extract any materials from the tubing, nor leave any residue. This process is normally conducted in a vapor degreaser, but can be done in cold-bath imersion pans. Fluorinated based solvents are preferred as they easily difuse into silicones. Fluorinated solvents are also non-flammable, and have a good toxicological profile.
