Introducing plastics by performance and application range
General-purpose plastics are plastics that have the largest production,wide supply,and low price,and are suitable for a large number of applications.General purpose plastics generally have good molding
Processability,a variety of processes can be used to form a variety of products.In general,general-purpose plastics do not have outstanding comprehensive mechanical properties and heat resistance,and are not suitable for carrying structural members requiring high structural strength and heat-resistant members operating at higher temperatures.However,various varieties of general-purpose plastics have their own excellent properties,making it widely used.Polyethylene,polyvinyl chloride,polystyrene,polypropylene,and phenolic plastics are collectively referred to as five general-purpose plastics.Other polyolefins,vinyls and their copolymers and modified materials,acrylic plastics,aminoplasts,etc.are also common plastics.Plastic raw material manufacturers
Engineering plastics are those that have outstanding mechanical properties,heat resistance,or excellent chemical resistance,solvent resistance,or good dielectric properties under varying environmental conditions.Engineering plastics can generally be used as load-bearing structural parts,heat-resistant parts and carriers in heating environment,heating conditions,humid conditions,dielectric products and insulation products under a wide range of frequency conversion conditions.Engineering plastics are produced in small quantities,are relatively expensive,and have a relatively narrow range of applications.Generally,a certain batch of materials is produced for certain special purposes.The main varieties of engineering plastics are polyamide,polycarbonate,polyoxymethylene,polyphenylene ether,ABS,PET,PBT,polysulfone,polyphenylene sulfide,chlorinated polyether,polyimide,polyetheretherketone.,fluoroplastics,ultra high molecular weight polyethylene,epoxy plastics and unsaturated polyesters.

3,special plastics have a special function,suitable for a special purpose plastic,such as for conductive,piezoelectric,thermoelectric,magnetic,photosensitive,anti-radiation,optical fiber,liquid crystal,polymer separation membrane,dedicated to friction Plastics such as wear and tear.Special plastics are also called functional plastics.The main components of special plastics are resins,some of which are special synthetic resins,but some of them are specially treated or modified with the above-mentioned general plastic or engineering plastics to obtain special properties.Plastic raw material manufacturers
