What are the four characteristics of paint packaging drums

1. 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 property of plastic also has certain defects, that is, it is easy to soften and deform when it is hot, and some plastics will be deformed even when hotted with hot water, so plastic products are generally not suitable for contact with boiling water.

2. The plastic has elasticity Some plastics, like synthetic fibers, have a certain elasticity. 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.

3. Plastics are resistant to corrosion Plastics do not rust in wet air like metal, and do not rot or be attacked by microorganisms in a humid environment like wood. In addition, 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.

4. Plastics have insulating properties. The molecular chain of plastics is a combination of atoms that are covalently bonded. The molecules are neither ionized nor transfer electrons in the structure, so the plastics are insulating. Plastics can be used to make electrical sheaths, electrical sockets, electrical enclosures, and the like.https://www.fhpails.com/
