Heat shrinkable products Installation Procedure

Before applying, always select the product in such a manner that the diameter following full recovery is only slightly less than the object that it is intended to cover. This will allow for maximum wall thickness, and therefore maximum insulation, protection and other properties.

If you are applying a tube, cut the tube to the length required (if not already precut), making sure that the cut has a straight edge. A poor or jagged cut may result in the tubing to split during application.

Slide the product over the application to be covered. Metal objects with a large mass should be heated prior to application to avoid uneven shrinkage of the product, or areas of poor shrinkage (Called “cold spotting”)

Shrink the product onto the object to be covered, starting at one end . Use a heating appliance for this procedure, for example a heat gun (we recommend the Master Mite range), a shrink tunnel or oven.

The optimal shrinking temperature as called out on our technical literature is vital to assure a short shrinking period and even shrinkage of the product. Thinner wall products will shrink faster than those with a heavier wall, and the object to be covered will be heat affected less during the process. Ensure even heat distribution in order to prevent overheating, Overheating of the product will cause bubbles or discolouration, or even splitting of the product.

Adhesive lined products may have a discharge at the open end of the product, This is normal, and allows for the environmental seal that it was designed.

After application, allow the product to cool before bending or installing the final unit.
