Mylar Heat Shrink Tubing is an easy-to-use product that works well as high-temperature and electrical insulation, extra protection, and even as replacement for tape. It is suitable for hand or machine application. No costly shrinking equipment is necessary. The tubing is spiral wound to most diameters and lengths. As a high dielectric insulation material, the shrinkable tubing makes a tight, smooth protective covering even in tight spaces. The tubing is shrinkable by as much as 50 percent of its diameter.
