What are the raw materials of plastic products in life? Resin? Or oil?

Answer:

Molded plastic: a resin mixture for molding. Such as thermosetting plastics.Laminated fabric: a fabric impregnated with a resin that can be laminated and pressed together to form an integral material.Injection, extrusion and blow molding plastics: - refers to a mixture of resins that can melt and flow at the cylinder temperature and rapidly harden in the mold. Such as general thermoplastic plastics.Casting liquid: a liquid resin mixture that can be poured into a mold and hardened into a definite shape in case of no pressure or little pressure. Such as MC nylon.Reaction injection mold plastic: generally refers to liquid raw material, pressurized injection mold cavity, so that the reaction of curing, finished products. Such as polyurethane.
General Plastics: - General refers to large output, wide use, good formability, low price plastic. Such as polyethylene, polypropylene, PVC and so on.Engineering Plastics: - General refers to the ability to withstand certain external force, and has good mechanical properties and dimensional stability, high and low temperatures can still maintain its good performance, can be used as plastic parts of Engineering structures. Such as ABS, nylon, poly alum and so on.Special plastics: - General refers to special functions (such as heat resistance, self-lubricating, etc.), applied to special requirements of plastics. Such as fluorine plastics, silicone and so on.
Molding powder: also known as plastic powder, mainly by thermosetting resins (such as phenolics) and fillers, such as through the full mixing, pressing and grinding and get. Such as phenolic plastic powder.Reinforced plastics: a class of plastics reinforced with reinforcing material and with greater mechanical properties than the original resin.Foam: overall contains countless microporous plastic.Thin film: generally refers to the thickness of O.25 mm below the smooth and soft plastic products.
There is no definite classification of plastics at present. The general classification is as follows: 1.. According to the physical and chemical properties of plastics, thermoplastics can be repeatedly heated, softened and cooled to harden in a certain temperature range. Such as polyethylene plastic, PVC plastic.Thermosetting plastics: Plastics cured by heat or other conditions without melting into insoluble material. Such as phenolic plastics, epoxy plastics and so on
Plastic is a kind of macromolecule organic material with resin as its main component. It can form a definite shape at a certain temperature and pressure and maintain a definite shape at normal temperature.Usually refers to the resin conversion or melting range when heated into force with mobility, at room temperature is organic polymer solid or semi-solid or liquid plastic, it is the most basic and most important components. Broadly speaking, in the plastics industry, any polymer used as a basic material for plastics can be called resins.
