Shrinking Tube
Heat shrink tubing is a heat-shrinkable plastic tube that is primarily used in optics to protect and repair eyeglass frames. When heated, the tube shrinks, fitting tightly to the desired surface, providing a secure hold and protection. It is often used to insulate metal temple ends, as well as to provide anti-slip and increased comfort. It can help protect glasses from scratches and corrosion during grinding or fitting. Heat shrink tubing is a simple yet practical solution in the everyday work of optical workshops.
