Although insulating tape is not often seen in life, its role can not be underestimated, many of the mobile phone explosions that have caused a lot of noise have finally been disclosed. The results show that some batteries have not used insulating tape and have caused great disasters. It is even more essential when decorating new houses or renovating circuits at home, today we will talk about those things about electrical tape. In the early days, insulating black tape was mostly used, which is generally directly called black tape. It uses cotton cloth as the base material, has good insulation and winding property, and is very cheap, but it is neither flame retardant nor waterproof, it has now been phased out. PVC electrical tape is currently the most widely used. It is made of polyvinyl chloride (PVC) The film is a base material and is made by evenly coating pressure-sensitive adhesive on PVC film. It has good insulation and withstand voltage below 600 V, flame retardant, weather resistance and other characteristics. The color of PVC electrical tape is not monotonous at all. It is available in red, blue, green, white, black and yellow. There is also a kind of high-pressure rubber self-adhesive tape, which is made of rubber, oil and calcium powder and can withstand high temperatures of up to 150 degrees. Its ductility is better than that of PVC electrical insulation tape, however, the strength is not as good as PVC electrical insulation tape, which needs to be used together with PVC electrical tape. The most commonly used of the above three kinds of adhesive tapes is PVC electrical insulation adhesive tape, which is mainly sold on the market at present. As it involves the safety of electricity, it is naturally not careless when purchasing, how can I buy PVC electrical tape that I can use with confidence? 1. Pay attention to the appearance of the tape. Mainly to see if there are burrs, the section should be flat, can not overflow glue or glue. 2. Insulation performance is different. Although PVC electrical tapes have insulation characteristics, different manufacturing processes will lead to different insulation properties. For example, a lot of fillers are added to the PVC substrate, and the anti-whitening phenomenon is obvious after use. At this time, its insulation performance has decreased a lot. 3, lead-free use to rest assured. Lead in PVC products is a frequently mentioned problem. Lead-free electrical insulation tape can be selected, which is environmentally friendly and lead-free, and is safe to use. Finally, when purchasing PVC electrical insulation tape, you should not covet cheap prices and try to purchase it through regular channels. Guangzhou ruidetai Electrical Equipment Co. , Ltd. was established in 2006 and is the largest PVC tape production base in Guangzhou. The company's main products are PVC electrical tape, PVC electrical insulation tape, PVC cold-resistant electrical tape, PVC extremely sticky electrical tape, PVC flame retardant electrical tape, automotive wiring harness tape, warning tape, pipe tape, high pressure self-adhesive tape, waterproof tape, audio shoe material protective film, easy to tear (Knife-free)Tape, PVC protective tape, etc. The company adhering to' Resolutely improve user satisfaction and win the continuous trust of customers' Of management concept in production process in'Strong adhesion is the last word' For the technical concept, strict implementation of ISO9001 international quality standard system, high-quality products and services have won strong recognition and trust from customers.
