Heat Shrinkable Mylar TUBING
General Description: A superior, high dielectric insu-lating tubing that is shrinkable as much as 50% in order to provide an immovable, tight fit. Temperature requirements are approximately 90¡ãC. for shrinking purposes with a heat cycle as short as 1 second. May be shrunk by various methods such as heat guns, boil-ing water, electrical coil heaters or in ovens.
Advantages: Heat shrinkable Mylar? tubing has a dielectric strength far exceeding other shrinkable materials. It is extremely tough and forms an excel-lent mechanical barrier. It can be used at both low and high temperatures. It is moisture & vapor resistant and is unaffected by oils, greases and volatile aromatics.
Application
Mostly used welding point,contact,loop,transformer,motor,electrical wire,electric heating componet,capactiance,telephony relay , high voltage transformer, temperature resistance and insulation,mechanism protection.Capacitor covers, RF & IF coil insu-lation, varnish masking, roller covers, lead binding & holding, battery covers, color coding, insulation between coils, sleeving insulation over wire leads, protective coverings.
