Frequently Asked Questions (FAQ)
-
What does a 2:1 shrink ratio mean?
A 2:1 ratio means the tube's recovered (shrunk) inner diameter is approximately half of its original expanded inner diameter. For example, a 20mm tube will shrink down to about 10mm. -
What is the best way to apply this heat shrink tube?
Use a standard electric heat gun. Move the heat source evenly along the length of the tube, avoiding concentrating heat in one spot. The tube will shrink smoothly and conform to the shape beneath it. -
Can this tubing be used outdoors?
Yes, the material formulation offers good UV resistance and environmental protection, making it suitable for many outdoor applications. For extreme UV exposure, specific UV-stable grades may be recommended. -
Is it resistant to oils and chemicals?
Our standard polyolefin tube offers good resistance to many common chemicals, oils, and solvents. For specific aggressive chemicals, please consult our technical support for material suitability. -
What is included in the warranty and technical support?
The warranty covers material and workmanship defects. Our technical support team, based on our manufacturing expertise, can assist with application questions, material selection, and problem-solving for your specific projects. -
Can I get custom colors or sizes?
Yes, custom colors, sizes, and printing (like wire markers) are often available. Please contact us with your specific requirements for a quotation. -
What is the shelf life of the product?
When stored in its original packaging in a cool, dry place away from direct sunlight, the heat shrink tube has a shelf life of several years without significant degradation of performance. - Is the tube adhesive-lined? Our standard product is a single-wall, non-adhesive tube. Adhesive-lined (dual-wall) versions that provide a waterproof seal are available as a separate product line upon request.
