Electrical tape, standard black. Electrical tape (or insulating tape) is a type of pressure-sensitive tape used to insulate electrical wires and other materials that conduct electricity. It can be made of many plastics but PVC (polyvinyl chloride, "vinyl") is the most popular, as it stretches well and gives effective and long-lasting insulation.

This is a list of insulation materials used around the world. Typical R-values are given for various materials and structures as approximations based on the average of available figures and are sorted by lowest value. R-value at 1 m gives R-values normalised to a 1 metre (3 ft 3 in) thickness and sorts by median value of the range.
Electric heat tracing, heat tape or surface heating, is a system used to maintain or raise the temperature of pipes and vessels using heat tracing cables. Trace heating takes the form of an electrical heating element run in physical contact along the length of a pipe.

In Europe, a double insulated appliance must be labelled Class II or double insulated or bear the double insulation symbol: ⧈ (a square inside another square). As such, the ...
With the exception of black, they tend to have lower resistance to ultraviolet light; accordingly, only black is recommended for outdoor applications. Polyolefin tubing shrinks at 143 °C. [ 9 ] Polyolefin heat-shrink tubing typically shrinks 2:1 diametrically, [ 10 ] [ 9 ] but high-grade polyolefin heat-shrink is also available with a 3:1 ...
