Polyolefin is the standard bearer of the shrink tube market. The shrinkage ratio is 2 to 1, uniform heating, no bubbling, no splitting, and self-extinguishing. It also provides greater flexibility than PVC shrink tubing. The maximum temperature is 275 degrees Fahrenheit, which complies with UL 224, CSA 198.1 and MIL-I-23053/5.
PVC shrink tubing is not as easy to install as polyolefin, but it does provide better chemical resistance and a tougher outer layer. It is also better able to resist direct sunlight. Provides a shrinkage ratio of 2 to 1, with a maximum temperature of 221℃f, meeting MIL-I-23053/2, MIL-DTL-2 level 2, UL 224 VW-1 and CSA OFT recognition.

The adhesive lining allows the shrink tube to connect to its own wire or terminal, and it is encapsulated to give it a watertight seal. Applications using this shrink tube require protection from elements or contaminants. High shrink ratio (3 to 1) makes odd-shaped connectors or applications easy to bridge and package
Adhesive lined shrink tubes are suitable for odd shapes (4 to 1). This shrink tube has a shrink ratio of 4 to 1, which can encapsulate any strange shape you might need to seal permanently. The adhesive lining allows the shrink tube to connect itself to the wire or terminal for a watertight seal.
The heavy-duty wall shrink tube is suitable for the most severe applications, including direct burial, diving, corrosion, severe mechanical and high pressure work.
