The raw material of plastic barrels is a kind of synthetic polymer material with a wide range of uses. Plastic products abound in our daily lives. The material of plastic barrels has the following four characteristics:
1. Plastic is malleable. As the name implies, plastic is a material that can be molded. The so-called plasticity of plastic means that the solid plastic can be softened by heating, and then the softened plastic is placed in the mold and allowed to cool and re-solidify into a solid shape.
This property of plastics is also flawed, that is, it is easy to soften and deform when exposed to heat. Some plastics can even be deformed after being scalded with hot water. Therefore, plastic products are generally not suitable for contact with boiling water.
2. Plastics are elastic. Some plastics are also elastic like synthetic fibers. When it is stretched by an external force, the curled molecules are straightened by flexibility, but once the tension is removed, it will return to the original curled state, which makes the plastic elastic, such as those of polyethylene and polyvinyl chloride. Film products. But some plastics are not elastic.
3. Plastics have corrosion resistance. Plastics are neither rusty in humid air like metals, nor rot or eroded by microorganisms in humid environments like wood. In addition, plastics are resistant to acid and alkali corrosion. Therefore, plastics are often used as water and liquid pipelines in chemical plants, doors and windows in buildings, and so on.
4. Plastics have insulating properties. The molecular chains of plastics are covalently bonded by atoms. Molecules can neither ionize nor transfer electrons in the structure, so plastics have insulating properties. Plastics can be used to manufacture wire wraps, electrical sockets, and electrical appliances.
