Plastic cap material and scope of application

There are two kinds of plastic caps: inner caps and outer caps, which are suitable for steel pipe fittings. Thermoplastic plastic cap: refers to the plastic that melts when heated, can flow to the mold after cooling, and then melts after heating; then heating and cooling can be used to make it reversible change, that is, the liquid becomes solid, which is The so-called physical changes. General-purpose thermoplastics have continuous use temperatures below 100°C. Polyethylene, polyvinyl chloride, polypropylene, and polystyrene are also referred to as four general-purpose plastics.

The scope of application of plastic pipe wool is also very wide, including nuclear power, aviation, electronics, construction, precision instruments, oil, natural gas, chemical industry, food, water conservancy, electric power, pressure vessels, machining and other industries.
