How to do plastic testing? What are the testing standards and items? Today, BAIJIAN will introduce the relevant content of plastic testing to everyone
Plastics are polymer compounds formed from monomers through addition polymerization or condensation polymerization. They have moderate deformation resistance, intermediate between fibers and rubber, and are composed of synthetic resins and fillers, plasticizers, stabilizers, lubricants, pigments, and other additives.
The main component of plastic is resin. Resin refers to polymer compounds that have not yet been mixed with various additives. The term resin was originally named after lipids secreted by animals and plants, such as rosin, shellac, etc. Resin accounts for approximately 40% to 100% of the total weight of plastic. The basic properties of plastics are mainly determined by the nature of resins, but additives also play an important role. Some plastics are basically composed of synthetic resins without or with little additives, such as organic glassTest items:
