materials for mobile phone case


what is silicone material?

silica gel : silicone rubber is a highly active adsorption material, which belongs to amorphous material, and its chemical molecular formula is msio2. nh2o. insoluble in water and any solvent, non-toxic and tasteless, chemical property is stable, except for strong alkali, hydrofluoric acid and no reaction with any substance. different types of silica gel form different microporous structures because of their different manufacturing metho ds.

advantages: the price is cheap, the adsorption performance is high, the buffering performance is good, it is not easy to wear, and the protection is more comprehensive.

shortcomings: the texture is thick, the style is small, the oil is greasy, and the fitting of the fuselage is a little bad. at the same time, the poor material is also easy to be stained with ash and ash.

silicone sleeve also has a good sense of hand, to a certain extent to reduce the damage to the mobile phone. in addition, the silicone sleeve also has a good waterproof performance, which has become one of its biggest selling points.

tpu material

tpu is the main material for making clean water sleeves, and is the abbreviation of thermoplastic urethane thermoplastic polyurethane elastomer.
tpu as elastomer is a material between rubber and plastic. it is oil resistant, water resistant and resistant to mould. the bearing capacity, impact resistance and shock absorption performance of tpu products are outstanding. tpu belongs to plastic products, injection molding process is done, is the one of the plastic melt in the barrel heating meter, injection plastic mould made products.

advantages: high wear resistance, high cold resistance, oil resistance, water resistance, mildew resistance and good flexibility

deficiency: easy to change yellow

from the feeling of feeling, the hardness of the general tpu will be harder than the silica gel. the elasticity of the hand is strong and the elasticity of the silica gel is a little worse. from the outside, tpu can do a kind of transparent silica gel, can not, most thoroughly is the kind of thick fog is hazy feeling like. it is the transparent feeling of tpu, which is now popular with users. and tpu products are still a lot of high grade, which can be more selective, and more pattern changes than silica gel.

pc material

pc is the abbreviation of polycarbonate, polycarbonate english polycarbonate, pc engineering plastics, a kind of pc material is actually what we say as engineering plastics, widely used in the world, pc has its own characteristics and advantages and disadvantages of pc, is a kind of comprehensive performance of amorphous type excellent heat the thermoplastic resin has excellent electrical insulation, extensibility, dimensional stability and chemical resistance, high strength, heat resistance and cold resistance; also has the advantages of self extinguishing, flame retardant, non-toxic, can be colored, in every corner of your life can see pc plastic shadow, large-scale industrial characteristics production and easy processing also makes it extremely low prices.
advantages: good transmittance, strong hardness, resistance to fall, light, strength and toughness
shortcomings: not resistant to scraping, strong acid, strong alkali, and uv resistance

pc material protection shell is different from silica gel and tpu protective shell. it is hard, pc plastic has good toughness and light transmittance. pure pc plastic has pure transparent, transparent black, transparent blue and other colors, and it is pretty good.

Different flexibility

the flexibility of the protective shell mainly refers to the nature of the protective shell which is not easily broken after the deformation of the shell. the flexibility of the protective shell can be said to be the biggest difference between three materials of silica gel, tpu and pc in appearance and feeling.

silicone protective sleeve is usually soft, tensile and smooth. if silicone material is added too little, it will easily be broken. how do we know its high tensile force? pull the product with the power of the right hand. if the product is turned white, it will be too small. if you pull hard or turn white, it will be a qualified product.

the hardness and hardness of tpu is between rubber and plastic. the hardness range of tpu is quite wide. by changing the ratio of tpu components, different hardness products can be obtained, and with the increase of hardness, its product still maintains good elasticity and wear resistance. as we all know, wear resistance, tear resistance and flexing strength are excellent. tensile strength, elongation, and long compression rate are all significant advantages of tpu.

tpu phone case

pc (polycarbonate) itself is a tough thermoplastic resin pc material, strong impact resistance, strength and good toughness, regardless of weight or general beat, as long as you're not trying to hit it with a stone, it is enough to live long, and high transparency but its appearance is easy to scratch.
