China Ultra-Thin Polyimide Tape for Circuit Boards Manufacturers, Suppliers, Factory

​Stretch film can also be called PE stretch wrap film. The principle of the stretch film is to wrap the items tightly together with the help of the film's super strong wrapping force and retraction, and to fix them into a unit to prevent them from falling off.

Waterproof tape is a self-fusing, conformable electrical insulation and waterproof sealing tape. It has strong surface adhesion and good thermal stability. It can be used for electrical insulation and waterproof sealing. Waterproof tape can be used in conjunction with PVC tape to provide reliable waterproof sealing and insulation protection for electrical circuits.

Before applying the anti-slip tape, you need to ensure that the pasting surface is clean, dry, and oil-free. If necessary, you can use a cleaner to clean the surface and paste it after it is completely dry.

While people are aware that the cross-sectional area of power cord materials affects electrical safety during electricity use, they often don't pay enough attention to the use of insulating tape at joints. Improper use of insulating tape can cause leakage, endangering personal safety or causing fires. So, how should insulating tape be used correctly? Power cord joints are divided into "+" type, "-" type, "T" type, etc. The joint should be securely wrapped, smooth and free of burrs. Before breaking the wire end, lightly press it with wire cutters, then wrap it around to the opening, and then swing it left and right; the wire end will break off neatly at the joint. If the joint is in a dry place, first wrap it with two layers of insulating black cloth, then two layers of plastic tape (also called PVC adhesive tape), then wrap two or three layers of J-10 self-adhesive insulating tape stretched to about 200%, and finally wrap two layers of plastic tape.

When choosing high-temperature tape, you must first consider its usage environment. For example, working environment temperature, humidity, corrosion conditions, etc.

According to statistics from the China Adhesives and Adhesive Tapes Industry Association, my country's tape sales have maintained a growth trend.
