What are the characteristics of the plastic barrel material?

First, the plastic has plasticity

As the name suggests, plastic is a material that can be shaped. The so-called plasticity of plastics is that the solid plastic can be softened by heating, and then the softened plastic is placed in a mold, which is allowed to cool and then re-solidified into a solid of a certain shape. This kind of plastic also has certain defects, that is, it is easy to soften and deform when it is hot. Some plastics will be deformed even when hotted with hot water, so plastic products are generally not suitable for contact with boiling water.

Second, plastic has elasticity

Some plastics also have a certain elasticity like synthetic fibers. When it is stretched by external force, the curled molecules are straightened by flexibility, but once the tension is removed, it will return to its original curled state, which makes the plastic elastic, such as polyethylene and polyvinyl chloride. Film products. But some plastics are not elastic.

Third, plastic has a higher strength

Although plastic is not as hard as metal, it has higher strength and wear resistance than glass, ceramics, and wood. Plastic can be made into sturdy gears and bearings on the machine.

Fourth, plastics have corrosion resistance

Plastics do not rust in the humid air like metal, do not rot or be attacked by microorganisms in a humid environment like wood, and the plastics are resistant to acid and alkali corrosion. Therefore, plastics are often used as water and infusion pipes for chemical plants, doors and windows of buildings, and the like.

5. Plastics are insulated

The molecular chain of plastic is a combination of atoms that are covalently bonded. The molecules are neither ionized nor electrons are transferred in the structure, so the plastic is insulating. Plastics can be used to make electrical sheaths, electrical sockets, electrical enclosures, and the like.
