There are many types of plastic products, each of which has its own unique advantages, and the products made by different types are different. Plastic products can also be divided according to their different materials, properties and so on. Specifically, how do you tell Linyi plastic products wholesale manufacturers?
Divided by flammability:
flammable plastic, this type of plastic burns after the fire, it is not easy to extinguish. Such as nitrocellulose plastics, such plastics are classified as dangerous goods.
flammable plastics, such plastics burn in open flames, no self-extinguishing, but burning faster. Such as polyethylene, polypropylene and so on.
flame retardant plastics, which can be burnt in a strong open flame and extinguished quickly after being fired. Such as phenolic plastics, acetate plastics, polyvinyl chloride plastics, etc.
According to the performance score after heating:
thermosetting plastic: This type of plastic is characterized by curing at a certain temperature after a certain period of heating or adding a curing agent. The cured plastic has a hard texture and is insoluble in any solvent and cannot be softened again by heating. When the heating temperature is too high, it will decompose.
Common thermosetting plastics are: bakelite, jade, decorative panels and unsaturated polyester plastics.
Thermoplastics: This type of plastic is characterized by heat softening, cooling and hardening, and generally only physical changes during processing to maintain its chemical nature. The plastics of this type of plastic are mostly made of polyaddition.
Common thermoplastics are: nitrocellulose plastics, acetate plastics, polyethylene plastics, polypropylene plastics, polystyrene plastics, polyvinyl chloride plastics, etc. For example, our common mineral water bottles, plastic bags, etc. It can be seen that the materials of plastics are different, and each kind of plastic products is different. Therefore, when we choose products, we should select materials according to the type of products to ensure the time in use.
