Heat-shrinkable tapes provide a uniquely effective means of applying skin-tight insulating and protective coverings for a wide variety of electronic, electrical, electro-mechanical and mechanical applications.
The cross-linking of polyethylene and its copolymers by means of high energy electron irradiation induces a permanent "memory effect". Such irradiated polymers are non melting, exhibiting perfect elasticity above their crystalline melting point. Supplied in an oriented form, the application of heat will shrink this material to its original dimention, the phenomenon referred to as elastic memory.
Heat-shrinkable tapes are quickly wrapped around the item to be encapsulated. When moderate heat is applied, the heat-shrinkable tape molds itself in a permanent skin-tight protective covering around the object. Installation can be easily performed using a variety of hot air or infrared heating tools depending upon production requirements. The electrically-powered hot-air blowers and gas-fueled torches are the most widely used tools for applying heat-shrinkable tapes.
Heat-shrinkable tapes are widely used in various branches such as the electronic industry, the car industry, the aircraft and ship building industries, the mining industry and many others.
All these tapes can be applied to electrical insulation, cable jacketing, bunching of wires, environmental protection.
Heat-shrinkable tapes with glue (TKT) we recommended for sealing for air conditioning duct joins. Heat-shrinkable tapes are charecterized by improved thermal resistance and can be applied in wide range of temperature between -40 and +105ºC. As compared with unirradiated material their mechanical properties are definitely better as well as their resistance for the action of aggresive chemicals, corrosion and atmospheric conditions.
Heat-shrinkable tapes lined with hot-melt adhesive and butylrubber are used as a sealing of joints preinsulated heating pipes.
