As an accessory of electronic products, the main function of silicone sleeve is to protect the surface of the product from scratches and dirt. We all know that most of the casings of handheld electronic devices are designed with hard mirror plastic casings or metal casings in order to pursue the beauty of the surface. It won't take long for the surface to be scratched, serious or even discolored. Such a new machine will soon become old, and a device that is as little as a few hundred yuan or More than a thousand yuan will be worth a lot of wear and tear on its appearance. Therefore, careful consumers will think of many ways to protect their machines. Before the appearance of silicone covers, careful manufacturers will match these devices with a leather or cloth cover. 
But in fact, due to the inconvenience of use, these accessories are often put aside by users, because if you put on a leather or cloth cover during normal use, it will often affect the normal operation, especially mobile phones with The button-operated handheld device, and the Silicone Case just has the characteristics that the leather case and the cloth case do not have. The silicone material is transparent, soft and elastic, and it is completely fitted on the machine and will not affect the control of the machine. In addition, the silicone sleeve is formed by the design of the mold, so the manufacturer will fully consider the maneuverability to ensure that the silicone sleeve does not need to be removed from the machine as often as the leather sleeve and the cloth sleeve after being put on the machine, which is greatly convenient for users. , In addition, the material used in the silicone sleeve has very good inertness, will not react with any other acid and alkali products under normal conditions, and is waterproof, high temperature resistant and heat insulating. Therefore, the silicone sleeve is a good protective device for protecting handheld electronic devices. Such as mobile phones, tablets, MP4, etc. application Silicone sleeves are the category of silicone gifts in silicone products. Silicone sleeves are widely used and are commonly used in Mp3/Mp4 players, iPods, PDAs, mobile phones, PSPs, digital cameras, GPS and other common personal consumer electronics products. The main function is to protect electronic products from falling and scratching; The material of the protective cover is soft and elastic, and it protects the equipment. According to the thickness of the silicone cover, it has a certain buffering effect. If the thickness is sufficient, and the structure design is reasonable, the protected product can have a drop-proof function (both in normal use state). , If it accidentally slips to the ground, it can effectively avoid the damage caused by the collision between the machine and the ground). The corresponding silicone sleeves are called Mp3 silicone sleeves, Mp4 silicone sleeves, iPod silicone sleeves, PDA silicone sleeves, mobile phone silicone sleeves, PSP silicone sleeves, digital camera silicone sleeves, GPS silicone sleeves. effect 1. Prevent hard objects from leaving scratches on the screen or body of the mobile phone. 2. It can be printed with various colors, beautiful and generous. 3. Prevent the fingernails from being scratched and worn in contact with the buttons for a long time, and has the function of protecting the screen and buttons; 4. Anti-slip effect; and the feel quality is very good. 5. The Apple mobile phone case also has the function of enhancing the signal, because the magnetic field formed by some mobile phone shells in contact with the metal interferes with the mobile phone signal. Putting an insulating mobile phone case on the mobile phone can enhance the signal. 
material The material of the silica gel sleeve is a highly active adsorption material, which is an amorphous substance, and its chemical formula is mSiO2·nH2O. It is insoluble in water and any solvent, non-toxic and tasteless, chemically stable, and does not react with any substances except strong alkali and hydrofluoric acid. The chemical composition and physical structure of silica gel determine that it has many characteristics that are difficult to replace by other similar materials: high adsorption performance, good thermal stability, stable chemical properties, and high mechanical strength.
