What is Heat Shrink Used For? Tech Data. List of Sku. Reviews There are tubing products designed with higher temperature ratings and without shrinking abilities, but polyolefin is standard. It can withstand high temperatures up to around degrees Celsius, making it appropriate for use in demanding environments. Standard sizes are , and — these ratios refer to the degree to which a piece of tubing will shrink down from its original size. For instance, a piece of tubing with a ratio will shrink to half its original size.
Tubing is also available in flexible and adhesive options. Flexible tubing is used on wires that need to bend, and adhesive-lined tubing uses glue on the inner layer that melts as heat is applied to make a more secure connection once it dries. Our heat shrink tubing products for sale online come in multiple colors to choose from.
These are instances where the electrical wires often get exposed to extreme heat or become prone to abrasions or short circuits.
These accidents would have been prevented if heat shrink tubing was used to protect the electrical wires from exposure. Heat shrink tubing is a mechanically expanded tube or tape that you can use to protect electrical wires or some minor electrical parts from harsh environmental elements. Heat shrink tubing is usually made of polyolefin or nylon, materials that shrink whenever they are heated.
After they cool off, they return to their original relaxed state or diameter. There are many different types of shrink tubing, all designed for different purposes. Shrink tubings are usually available in a wide range of colors. This makes it easier for people to color-code their connections. Heat shrink tubing also comes with varying shrink temperatures. This refers to the heat required to shrink the tubing.
Polyolefin heat shrink tubing usually requires higher temperatures than PVC tubing. Typically, this temperature is applied via a hand-held heat gun. However, manufacturers may use a flow-through oven for more thorough heat exposure for high production levels. Getting the right product is more than just a quick transaction to buy the right diameter and shrink ratio. Has your potential supplier experience of their products in multiple markets?
Do you need it cut to a specific size or in a special way? For example:. Different sizes, colours and lengths all ready and prepared as per your component list or bill of materials so all your assembly team need to do is open the lid of the kit and start work.
How would you like your product packaged? Can your supplier keep it for you until you are ready just-in-time? Would it help to plan the inventory and delivery scheduling? How do you avoid this? Look for quality assurance. How does your potential supplier prevent mistakes and avoid problems? Are they certified to ISO , the international standard for a quality management system QMS which means they are focussed on:.
What are some good alternatives? Strip a piece of thick wire and use the insulation as a sleeve to slide over the joint. First of all make sure you have shrinkable tubing and for best results use only a size slightly larger in diameter then you need. It will only shrink so much. There is tubing out there that is non- shrinkable.
