What is the material of SAN, and what does it mean to be plastic?

SAN is also AS, a kind of plastic, acrylonitrile-styrene resin Acrylonitrile-Styrene resin, it is estimated that it has other meanings in other fields, such as the meaning in the satisfactory answer. However, it is also a type of plastic.

AS is san, which is styrene-acrylonitrile.

Copolymer. Acrylonitrile-styrene copolymers are prepared from acrylonitrile and styrene by bulk method, suspension method or emulsion method. Transparent or translucent water-white particles.

Relative density. 1．06-1．08。Refractive index.

1．57。Equilibrium water absorption 0 66%. Heat deflection temperature 82-105.

It has high gloss, high transparency, high impact, good heat resistance and mechanical properties. It has high rigidity, high chemical stability, and is resistant to water, oil, acid, alkali and alcohol.

AS is san, which is styrene-acrylonitrile copolymer!

AS is a copolymer of propylene-styrene, also known as SAN, with a density of about one, and is a polymer compound formed by the copolymerization of acrylonitrile and styrene. Generally contains 15%-50% styrene. Transparent solid with yellow to amber needle color.

Density. Thermoplastic. Not easy to change color.

Unaffected by dilute acids, dilute alkalis, dilute alcohols and gasoline. However, it is soluble in acetone, ethyl acetate, dichloroethylene, etc. It can be used as an engineering plastic.

It has excellent heat and solvent resistance. It is used to make oil-resistant mechanical parts, instrument shells, instrument panels, battery boxes, tractor fuel tanks, battery shells, packaging containers, daily necessities, etc. It can also be drawn into monofilament.

However, it is mainly used as a blend for the production of ABS resin.

SAN is a plastic material. The full name is styrene acrylonitrile qiaotong copolymer.

Styrene acrylonitrile copolymer is a colorless and transparent thermoplastic resin with high temperature resistance, excellent gloss and chemical resistance, as well as excellent hardness, rigidity, dimensional stability and high load-bearing capacity. It can be obtained by polymerization with acrylonitrile and styrene as raw materials by suspension method, which can also be initiated by hot slippery initiator, or prepared by emulsion polymerization method. Due to the inherent transparency of the resin, Shinhiro bend is very commonly used in the manufacture of transparent plastic products.

Styrene acrylonitrile (SAN).

SAN is an abbreviation for Styrene Acrylonitrile. Styrene acrylonitrile is a copolymer of styrene acrylonitrile, which is a colorless and transparent polypropylene-based engineering plastic with high mechanical strength. SAN is chemically stable better than polystyrene.

The transparency and UV resistance of SAN products are not as good as those of polymethyl methacrylate products, but they are relatively cheap.

SAN AS Plastics.

Chemical name: acrylonitrile-styrene copolymer.

English name: acrylonitrile-styrene Characteristics of raw materials:

1. It is a kind of ethylene, which is a general ordinary material and is easier to form plastics.

2. Good fluidity, good formability, good molding energy rate.

3.Sturdy and rigid.

4.Good long-term resistance to light and heat.

5. Good dimensional stability, weather resistance, oil resistance, vibration resistance and chemical stability 6. Dissolved in organic solvents such as ketones.

7. Easy to crack.

8. It is easy to waste edges.

SAN is styrene-acrylonitrile copolymer (English: Acrylonitrile-Styrene Copolymer, also known as AS resin), is a colorless and transparent thermoplastic resin, with high temperature resistance, excellent gloss and chemical resistance, as well as excellent hardness, rigidity, dimensional stability and high bearing capacity, is obtained by suspension polymerization of acrylonitrile and styrene as raw materials, and can also be initiated by using heat initiators. It can also be obtained by emulsion polymerization, which is used in the manufacture of transparent plastic products due to the inherent transparency of the resin.

Can you state your problem again? Maybe my comprehension is not enough, the code name SH special steel is to make the atomic bomb, it is ASSAB steel, composition: carbon, silicon, chromium, manganese, vanadium.

Ask what materials can be substituted in China.

So it's not easy to find an alternative, and of course it doesn't support this approach: ordinary steel is produced in large-scale steelmaking plants using iron ore as raw material. The iron ore is reduced by coke and hot air gas in the blast furnace, and further carburized to become molten iron, and then the molten iron is oxidized at high temperature in the LD converter, and after adding silicon, manganese, aluminum, etc., it is deoxidized again, and then continuously cast into small billets, large billets and flat billets, etc., or cast into steel ingots and then made into semi-finished products by opening the billets, and then heated and rolled into the final shape of the product.

The melting of special steels begins with electric furnaces. The main raw material is scrap steel, which is melted in an electric furnace and refined in various ways, and the alloy composition is adjusted, and then continuously cast into billets or directly cast into ingots, and then calendered or forged into the desired shape.

This is the difference between ordinary steel and special steel that you can take a look at.

You know the difference between ordinary steel and special steel.

So there is no material that can replace special steel.

SAN also has a name called AS, which you can easily look up on the Internet.
