What are plastic screws, and what are the common advantages and disadvantages of pp screws?

PP is polypropylene (PP plastic), which is another excellent resin species developed after nylon. It is a linear polymer with high density, no side chains, and high crystallinity, with excellent comprehensive properties. When uncolored, it is white translucent, waxy; lighter than polyethylene. Transparency is also better than polyethylene and harder than polyethylene. It is not to say that PP can be modified. Plastic screw is a type of screw made of plastic.

Plastic screws are made of hot melt injection molding. They are divided into main materials: nylon PA66 screws, PP screws, PVC screws, PE screws, etc. The characteristics of each material are different, so the scope of application is also different. Compared with traditional metal screws, plastic screws have excellent performance in many aspects.

Compared with metal screws, plastic screws have good insulation properties and are not conductive; in addition, because of non-metal manufacturing, they will not produce signal interference such as eddy current under the influence of current or other electrical signals, and their anti-interference ability is also very strong. ; The major defect of plastic screws is that the torque and strength of ordinary plastic screws are not as good as ordinary metal screws. If the torque is too large, there is the possibility of slipping teeth or breaking the head.

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. The best PVDF screws are followed by 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
