Polyolefin is the standard-bearer in the shrink tubing market. With a 2 to 1 shrink ratio, it heats evenly, doesn’t bubble or split, and is self-extinguishing. It also offers greater flexibility than PVC shrink tubing. Maximum temperature of 275° F. Meets UL 224, CSA 198.1 and MIL-I-23053/5.
PVC shrink tubing is not as easy to install as Polyolefin, but it does offer better resistance to chemicals and has a tougher outer layer. It also stands up better to direct sunlight. […]
