Plain Black PVC tapes are one variety of electrical tape, as mentioned above. Functional and durable, PVC (polyvinyl chloride) tape is contemplated as a ‘balanced’ plastic tape and is utilised in similar situations to vinyl electrical tape. However, PVC tape copes well with environmental factors and is frequently utilised for outdoor applications.
Plain Black PVC Tapes is a safety tape for wires, utilised to cover and insulate a broad range of cables, wires and other materials that conduct electricity. It’s frequently mentioned as insulating (or thermal insulation) tape, and its uses in the workplace and home settings are universal.
PVC tapes come in an array of breath and thicknesses for numerous non-identical uses, as well as in a selection of colours and materials for optimal insulating properties and accurate colour-coding of various wires for safety purposes.
In this article, we’ll look more closely at some of the specific uses for PVC tape, its key safety features, and a number of the most common kinds of electrical tape available for sale in India and beyond.
The key properties of a reliable and trustworthy PVC plain black tape are that it must:
a. act as an effectual insulator against electricity, safeguarding circuitry and users by not conducting current easily
b. be heat-resistant and fireproof to a reasonable degree for the application it’s being utilised in
c. be flexible, user-friendly and easy to apply to a range of wires, circuits and connections (frequently in relatively tight spaces)
By far the most common material for PVC tape these days is vinyl, but we’ll investigate more materials and their uses in a later section. For now, we’ll take a closer look at some of the general features of insulating tape listed above, and how best to use it to make the most of those key attributes.
When used properly, the PVC Plain Black Tapes should act as an insulator - that is to say, it should protect against the transfer of any electrical current passing through the wires to people or constituents potentially coming into contact with them. As such, properly rated and applied insulating tape should NOT conduct current.
Plain Black PVC Tapes are most commonly used in DIY applications for making repairs and joining smaller wires. As we’ll outline in more information below, it should not be utilised for major repairs to very badly damaged wires, or on its own for creating permanent connections in junction boxes, light switches, or wiring outlets.
In these sorts of high-demand, potentially high-temperature environments, the insulating tape should only be used in conjunction with purpose-made wire nuts and other connector tools for a safer and more secure fix. Furthermore, the PVC plain tapes shouldn’t be used as a standalone repair for damaged or unsliced wires in close proximity to soft furnishings or other flammable materials.
Although most well-respected brands of PVC will have decent thermal properties (normally to cope with temperatures up to around 80 degrees Celsius), numerous varieties of insulation tape are indeed flammable if they’re permitted to get hot enough.
The likelihood of combustion is generally reasonably low if it’s utilised sensibly and in the environment for which it was designed, but this will rely entirely on the application in question and the sort of tape being used.
Several varieties of PVC black tapes have much more advanced heat-resistant properties than others.
Select the Appropriate Grade
In cold conditions, you will need to select cold weather tape for better adhesion. Standard PVC tape can be used for all other applications like indoor settings. You should always pay attention to the min and max temperature ratings of the PVC tape to ensure you are using the correct one.
Half Lap Tape
The proper application of PVC tape is to half-lap, which results in a double layer of tape. The rule of thumb is to do a minimum of two half-lapped layers or one and a half times the thickness of the insulation of the wire that you are wrapping, whichever is greater. The tape should be thicker than the insulation, for added protection.
Stretch the tap as you Wrap
PVC Tapes work the best when it adapts to the object it is being applied to. When you go to apply your PVC tape to a cord or piece of wire, you should stretch the tape as you wrap. When the tape is stretched as its being applied, it will provide more insulation protection than when it is applied loosely.
To create effective insulation, you should wrap the tape between 75% of its width to right before the breaking point. Doing this will ensure the tape will be able to withstand the elements. The last wrap should be applied with no tension to prevent flagging.
