4mm heat shrink tube is a 3:1 flexible tubing offering the advantages of integral, adhesive-lined construction. Heat Shrink Tubing & Sleeve is made from flexible polythene with an internal layer of special thermoplastic adhesive.
The heat-shrinkable outer wall is selectively cross-linked while maintaining the high flow and excellent adhesion of the inner sealant liner. When heated in excess of 121 deg C (250 deg F), the heat shrink tube rapidly shrinks to a skintight fit, forcing the melted adhesive lining to flow and cover the substrate.
The adhesive forms a flexible bond with a wide variety of rubbers, plastics, and metals. Upon cooling, the adhesive solidifies, forming a permanent, non-drying, flexible and water-resistant barrier. Adhesive re flow will occur at temperatures above 80 degree Celsius.
