All electronics need electricity. This electricity reaches them through wires and cables. For the containment of these electrical signals, one thing is of the utmost importance: insulation. Insulation tapes and layers are used on wires to protect them from heat damage and electromagnetic interference. They also isolate the wire from outside bodies, controlling the flow of electricity. On Alibaba.com, you have access to wholesale white fr4, heat shrink wire connectors, white fr2, and much more. Start buying international wholesale products today.


The Vinyl PVC insulation tape is the most common one. The material is robust and resistant enough to high and low temperatures while having good adhesion and stretchiness. The PVC tape can also be used as a high voltage electrical tape. They are resistant to environmental hazards and corrosion. This makes them ideal for everyday patches and repairs on outdoor installations. The mastic tape is a mass of adhesive and insulating material with great stretchability and versatility. They are a good choice for bulk-wrapping certain sections of wire. The cotton tape for electrical insulation is ideal for lower voltages. The fiberglass tape is especially resistant to continuous exposure to high temperatures. The white fr4 also has its own specifications and uses.
