3M™ Heat Shrink Heavy Duty End Caps
Product Description Heat shrinkable end caps are typically used to seal cable ends and provide
mechanical and environme ntal protection.
When heated in excess of 121ºC (250ºF), SKE Heat Shrink Heavy Duty End Caps
rapidly shrinks, forcing the melted adhesive lining to flow an d 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 reflow will occur at temperatures above 80ºC
(176ºF).
