1. The main component of plastic raw materials is not graphite, but rather synthetic resins or polymers. Graphite is a form of carbon and is typically used in other applications such as lubricants or electrodes.
2. Plastic raw material refers to a substance primarily composed of polymer synthetic resin, which is combined with various additives or auxiliary materials. Under specific temperature and pressure conditions, it exhibits plasticity and fluidity, allowing it to be molded into a desired shape. Once cooled or solidified, it retains that shape, making it suitable for a wide range of manufacturing processes.
3. A polymer is a large molecule made up of repeating structural units, typically derived from monomers through a process called polymerization. Both natural substances like rubber and synthetic materials like polyethylene are considered polymers. These long-chain molecules give plastics their unique properties, such as flexibility, durability, and moldability.
4. Plastics are known for their excellent insulating properties. They provide good electrical insulation, resist arc formation, and are effective at retaining heat. In addition, they offer sound insulation, sound absorption, and vibration damping capabilities, making them ideal for use in noise control and acoustic applications.
