Simply put, plastic sheets can be made of plastic as raw materials, and PP plastic sheets are just one type. But the plastic we usually use is not a pure substance, it is made of many materials. Among them, high molecular polymers or synthetic resins are the main components of plastics. In order to improve the performance of plastics, various auxiliary materials must be added to the polymer, so that the performance of the plastic board will be improved.
Another point is that there are two substances, which confuse polyvinyl chloride resin with polyvinyl chloride plastics, and phenolic resins with phenolic plastics. In fact, resin and plastic are two different concepts. Resin is an unprocessed raw polymer that is not only used to make plastics, but also a raw material for coatings, adhesives, and synthetic fibers. In addition to a very small part of the resin containing 100, most of the plastics, in addition to the main component resin, also need to add other substances. In this way, the PP plastic board will play its role.
