Advantages and disadvantages of plastic screws 1. Compared with ordinary metal screws, the biggest advantage of plastic screws is that they have good insulation properties and are not conductive. 2. In addition, because of non-metal manufacturing, there will be no signal interference such as eddy current under the influence of current or other electrical signals, and its anti-interference is somewhat suitable for communications and other industries. 3. Plastic screws have better acid and alkali resistance. Among them, the best PVDF screw is polypropylene. Both have strong acid and alkali resistance. Compared with the former two, nylon screws are resistant to strong acids and alkalis. The performance is relatively poor, so in some strong acid and alkali environments in the electroplating industry, plastic screws, especially PVDF screws, have a wide range of applications defect: 1. The biggest disadvantage of plastic screws is that the torque and strength of ordinary plastic screws are n...
