What plastic materials are used in the phone case? How to buy mobile phone shell skills correctly

1.abs material mobile phone case: the most popular nowadays but poor corrosion resistance

If you talk about plastic, then you can't help but mention aBS plastic. This material is a synthetic element. It combines the various properties of PB, PaN and PS organically. It looks pretty good. The various advantages of these three materials, but relatively, the various shortcomings have also been "inherited", which is undoubtedly the most sad reminder.

aBS material phone case advantages:

1: The output is large, and Gu will not face the situation of out of stock.

2: Poor flammability, not dangerous

3: Relative wear resistance

Disadvantages:

1: Poor corrosion resistance

2: Poor toughness, not broken

Two.pp material phone case: the lightest but easily deformed

PP plastic (polypropylene) is another excellent resin developed after nylon. As a semi-crystalline material, it has high density, no side chain, easy bending, low hygroscopicity and high frequency insulation. It is non-toxic and heat resistant. The fork in our common barreled instant noodles is made of PP material. Therefore, it will not emit toxic substances when placed in boiling water, and it will not harm the human body.

PP material phone case

1: Low cost and low production process requirements

2: The medium is stable, and the mobile phone case is good after molding.

Disadvantages:

1: Flexibility and variability

2: It is not tight and can't play well.

Three.pc material phone case: good thermal stability but short life

PC is the abbreviation of polycarbonate. The English of polycarbonate is Polycarbonate, which is called PC engineering plastic. PC material is actually one of the engineering plastics we call. As a widely used material in the world, PC has its own. Characteristics, advantages and disadvantages, PC is an amorphous thermoplastic resin with excellent comprehensive properties, excellent electrical insulation, elongation, dimensional stability and chemical resistance, high strength, heat resistance and cold resistance. It also has the advantages of self-extinguishing, flame retardant, non-toxic, colorable, etc. The shadow of PC plastic can be seen in every corner of your life. The large-scale industrial production and easy processing characteristics also make it extremely inexpensive.

PC material phone case advantages:

1. Good transparency and hardness.

2. Anti-fall, light and thin, good strength and toughness.

Disadvantages:

1. Not resistant to scratching, not resistant to strong acid.

2. Not resistant to strong alkali, not resistant to ultraviolet rays.

PC material protective shell is different from silicone and TPU protective shell. It is hard. PC plastic has good toughness and good transparency. Pure PC plastic has pure transparent, transparent black transparent blue and other colors. Very good.

It is suitable for the mine with explosive dangerous gas and coal dust. It can control and protect the start and stop of less than 4 three-phase squirrel cage asynchronous motors in the AC 50 Hz and rated voltage ac1140v (660V), and the phase sequence can be changed when stopping. It is especially suitable for the centralized monitoring of mining, transportation, coal mining and other dynamic loads.
The flameproof shell of the combined switch is square and installed on the prying base. It is welded with 16mm thick Q235A steel plate, which is beautiful in appearance and durable in strength.
