Why source polyolefin heat shrink tubes from China?

What is Polyolefin Heat Shrink Tube

polyolefin heat shrink tube is a type of plastic tubing that shrinks when heated. It is made from polyolefin materials, such as polyethylene (PE) or polypropylene (PP). This type of tubing is commonly used in manufacturing, electronics maintenance, wire and cable protection, and many other applications.

The tubing shrinks by heating, hence the name "heat shrink tube." When exposed to a heat source, typically a heat gun or a shrink oven, it contracts and tightly wraps around the object it covers, providing functions such as protection, insulation, sealing, and labeling. Characteristics of heat shrink tubes include resistance to chemical corrosion, good insulation properties, temperature resistance, and durability.

 polyolefin heat shrink tubes are versatile engineering plastic products suitable for various applications, offering functions like protection, insulation, and encapsulation.
