All performance indicators about custom heat shrinkable tubing

Custom heat-shrinkable tubes are also called double-wall heat-shrinkable tubes. We usually call them double-walled tubes for short. The difference between them and ordinary heat-shrinkable tubes is that there is an extra layer of glue on the inner layer. This glue belongs to hot-melt adhesive and is usually solid. It turns into liquid glue when heated. Because it is solid, it is equivalent to two layers of inner walls together with the Heat Shrinkable Tube, so it is called double-wall heat shrinkable tube, or directly called custom heat shrinkable tube and glue-containing heat shrinkable tube.

When the customized heat-shrinkable tube is heated and shrunk, the inner hot-melt adhesive also melts and fills all the small gaps between the heat-shrinkable tube and the coated object. After natural cooling, the heat-shrinkable tube and the coated object are more sealed and waterproof , so hot melt adhesive is the soul of custom heat shrink tubing, and it acts as a medium to make the connection tighter.
Customized heat shrinkable tubing has different shrinkage ratios. The conventional ones are 2:1, 3:1, 4:1, and 6:1. The inner diameters range from φ2.4 to φ150. Two issues must be clarified when piping, one is the shrinkage ratio and the other is the inner diameter. Novice users can consult the product experts of heat shrink tubing, and we can provide you with detailed professional technical services.
PE heat-shrinkable sleeve; the main material of this heat-shrinkable sleeve is polyolefin, and the main application industries include new energy vehicles, power cables, electrical appliances and electronics industries. The rise in the price of polyolefin raw materials will have a certain impact on these four major industries. However, these four major industries are high value-added industries, and the cost of heat-shrinkable sleeves is not large, so the impact is minimal. The real impact is the rise in copper prices, which will cause greater fluctuations in these four major industries.
Double-wall heat-shrinkable tube: The outer layer of double-wall heat-shrinkable tube is modified polyolefin, and the inner wall is hot-melt adhesive. It is mainly used in ships, submarines, motors, small submersibles and other fields that need to be sealed and waterproof. These industries pay more attention to quality. The price factor is second, so as long as the quality is well managed, the overall impact will not be great.
Halogen-free heat-shrinkable tube; Halogen-free heat-shrinkable tube is a new product launched in recent years. It is mainly divided into two categories: halogen-free heat-shrinkable tube and red phosphorus-free heat-shrinkable tube. It focuses on environmental protection and is aimed at customers with relatively high environmental protection requirements. , It is also a better choice for exporting to Europe, America and other countries. The rise of raw materials has a negligible impact on halogen-free heat shrinkable tubes.
To sum up, the heat-shrinkable tubing industry is not insensitive to the price increase of raw materials, but the low-end backward production capacity is always more affected, and the demand for high-end heat-shrinkable tubing and environmentally friendly heat-shrinkable tubing will increase. The bigger it is, the price will not be the only factor for customers to choose suppliers, quality is the top priority!
Custom heat-shrinkable tubes are widely used in cutting-edge fields such as automotive wiring harnesses, shipbuilding, and aerospace. It is the largest manufacturer of custom heat-shrinkable tubes, busbar heat-shrinkable tubes, and red phosphorus-free heat-shrinkable tubes in China. Welcome to our company for inspection comminicate!
