The future of PVC heat shrink tubing
What will happen to PVC heat shrink tubing in the future?
What is PVC heat shrink tubing?
Heat-shrinkable tubing made from PVC (polyvinyl chloride) was once a widely used material for protecting electrical wires. Its excellent oil resistance, weather resistance, and insulation properties made it suitable for a wide range of applications, including electrical equipment and automotive devices.
One of their most representative products is the PVC tube known as "Hishi Tube," which boasted a particularly high share of the domestic market. However, in recent years, this PVC heat shrink tube has disappeared from the market and is no longer in production.
Background of discontinuation
Difficulty in responding to environmental issues
PVC is a material that contains halogens and there is a risk of chlorine gas being generated when burned , so it has come under strict evaluation due to strengthened environmental regulations such as RoHS and REACH.
As a result, PVC products were gradually replaced by halogen-free materials (such as polyolefins) , and demand for PVC products gradually declined.
In addition, regulations on PVC products, such as those under the US TSCA, are expected to become stricter in the future.
2. Price competition with polyolefin products
With the rise of low-cost, mass-produced polyolefin tubes , the price competitiveness of PVC products has declined significantly.
It seems that the benefits of choosing PVC based on price alone have diminished.
How to choose a replacement?
Nowadays, instead of PVC tubes, products made from the following materials are becoming mainstream.
| Material | Features |
|---|---|
| Polyolefin | Flexible, halogen-free, environmentally friendly, and cost-effective |
| Fluorine resin | High heat and chemical resistance |
| silicon | High flexibility, heat resistance, and suitable for medical applications |
| EPDM | Flexibility◎ |
Products that can be used for the same purposes as PVC tubing can be selected based on criteria such as shrinkage temperature, shrinkage ratio, heat resistance, and insulation performance .
For those in need
