Q:What are the raw materials needed for producing plastic hair dryer shell and flashlight shell?

PA nylon as a large amount of Engineering plastics. Widely used in machinery, electrical appliances, textile equipment, chemical equipment, aviation and other fields. Become an indispensable structural material in all walks of life, the main features are as follows:1. excellent mechanical properties. High mechanical strength and good toughness.2. excellent heat resistance. Such as nylon 46, high crystallinity Nylon high thermal deformation temperature, can be used at 150 degrees Celsius for a long time. PA66 after glass fiber reinforcement, its thermal deformation temperature above 250 degrees celsius.3. excellent electrical insulation performance. Nylon has high volume resistance and high breakdown resistance. It is an excellent insulating material for electrical and electrical equipment.4. self lubrication, good friction resistance. Nylon has a good self lubrication, small friction coefficient, so as to drive parts, long service life.5. excellent weather resistance.

Q:I do PA, PC, PP and other plastic raw materials can be used in the eye frame and lens it

In general, the lenses of PC need to be covered with scratch resistant protective films, which will be sufficient for better aging, and most lenses for children.

Q:What are the raw materials of foam plastics and how do they come out?

Chemical blowing agents are mainly azo organic compounds such as azo two formamide (ADCA or AC), 2, 2 '- azo two, DAB, AIBN, etc.. This kind of foaming agent is cheap, and the products are non-toxic, odorless and colorless. In addition to sulfonylhydrazine, such as 4, 4 '- oxo benzene sulfonyl hydrazide (OBSH) etc.. Attention should be paid to the decomposition temperature. The properties of chemical foaming agents are as follows:Azo two formamide (AC, ADCA). Orange crystalline powder. A large amount of gas (N2, CO and a small amount of CO2) is decomposed at 120 DEG C, and the gas yield is 200 ~ 300mL/g in the standard state, which is an efficient foaming agent.

Q:Characteristics and uses of CA plastics

Cellulose acetate (Cellulose Acetate, hereinafter referred to as CA, or cellulose acetate, cellulose acetate) was first prepared in 1865 and is the acetate of cellulose. CA used for photographic film base, is a component of some adhesive for synthetic fiber.

Q:What is the essential difference between plastic raw materials and engineering plastics?

Plastics can be divided into two major categories: General Plastics and engineering plastics. They are usually granular or powder in order to be easy to process before they are madeGeneral plastics refer to common plastics with large output, wide use, good formability and low price. Such as PVC, polyethylene, polypropylene, polystyrene and so on. Products made of plastic film, pipe, woven bags and plastic daily necessities. The yield and consumption of general-purpose plastics account for more than 80% of all plastics.Engineering plastics refer to plastics that meet the needs of industrial parts. Relatively speaking, they yield large, wide range of applications. Mainly ABS, polycarbonate, nylon, POM, modified polyphenylene ether, thermoplastic polyester and so on. Products have TV casing, plastic gears, optical materials, gaskets and so on.There is also a special engineering plastics, in addition to its characteristics of engineering plastics, its comprehensive performance is higher, long-term use temperature above 150 degrees celsius. It also has special functions and special uses. Mainly used in high-tech industries, such as atomic energy, rockets, satellites, aerospace, automotive, electronic and sports equipment, and other structural materials. Commonly used special engineering plastics are fluorine plastic, silicon resin, polyimide, peek, liquid crystal polymer and so on.

Q:How to make plastic raw materials?

oil refiningPetroleum crackingCracking is the process of breaking down hydrocarbons with relatively large molecular weight and high boiling point under certain conditions, which are relatively small molecular weight and low boiling point hydrocarbons.Cracking under catalysis, also known as catalytic cracking.

Q:What are the raw materials for making plastics?

Polymer: any of the pure or polymeric materials produced by the polymerization process, whether natural or synthetic resins, are polymers, polymers, or polymers

Q:Plastic raw materials, electroplating grade round face, electroplating grade, what is the concept?

The so-called plastic raw material electroplating grade means that the particle of the plastic material is high in purity and high in polarity, and is easy to be evenly adhered to the metal particles before the plating.

Q:What type of raw material is used in plastic bags? The brightness is good. It blows out as bright as a mirror! That kind of transparency!
