■Features
- It shrinks at a ratio of 6:1, making it ideal for objects with steps.
-This heat shrink tubing has strong insulating properties and is highly waterproof because a hot melt adhesive is applied to the inside of the heat shrink tubing .
- It is widely used in marine cables and automatic control devices to protect metal wires from moisture and to bundle wires.
- Use in areas with steps in hoses or connectors that cannot be covered with other companies' waterproof tubes or high-shrink tubes.
■ Recruitment history
・Railway vehicle, automobile, connector manufacturers, etc.
| Manufacturers | Situation before employment | Effects on recruitment |
| milling machine manufacturer |
・From 2018 |
By adopting our CF tube, waterproofing can now be completed with just one CF tube. This cut the amount of tubing purchased in half and the heat shrinking work in half. |
■Sales
・This product can be purchased in quantities starting from 1m.
-If you specify a length of less than 1m, we can cut it to the length you require.
■ Examples of made-to-order products
・Large diameter products of 100mm or more
