TPU protective film, it is not a glass material like 3D tempered glass film, but a material between rubber and plastic. This material is hydrophobic and oil resistant, and has good ductility, wear resistance, but also has good permeability. It is also an environmentally friendly material.

TPU protective film is a kind of polymer elastic material, which is a new type of environmental protection material. Its special molecular structure makes it have excellent physical properties, such as: high elasticity, wear resistance, high strength, hardness, ductility, water resistance, air permeability, oil resistance, mold resistance. TPU protective film can maintain long-term elasticity in the range of -60℃ to 200℃.

Application: TPU protective film is used in digital screen, electronic screen, automobile instrument, optical sheet, optical resin plate anti-shatter protection.

Storage conditions: Valid for 1 year, storage temperature 18℃-22℃ and relative humidity 60%RH. Optimum storage conditions: Temperature 22℃ and relative humidity 50%RH.

TPU features: excellent structural mechanical properties, wear resistance ground non-slip, excellent ultra-low temperature flexibility, excellent production and processing liquidity and rapid prototyping technology, low temperature and high temperature resistance, good clarity, stable extrusion performance, stable melting point.

Application and production process of TPU protective film

TPU film with its superior physical properties, practical performance, environmental protection performance, widely used in shoes, electronic devices, electric equipment, industrial equipment, auto parts, pipes, wires and cables, films and other daily necessities and industrial production industries.

TPU film production process and application of production and processing methods: injection molding, extrusion, injection molding, blowing film.

Polyester TPU film features: superior structural mechanical properties, wear resistance ground skid, excellent ultra-low temperature flexibility, excellent production and processing liquidity and rapid prototyping technology, low temperature and high temperature resistance, good clarity, stable extrusion performance, stable melting point. To put it bluntly, the elastomer refers to the glass transition temperature is less than the indoor temperature, the tensile strength is > 50%, and the fiber material with good reducibility after the external force is withdrawn. Polyurethane elastomer is a unique type of elastomer. Polyurethane elastomers have a wide range of hardness and performance. Therefore, polyurethane elastomer is a kind of fiber material in the middle of vulcanized rubber and plastic.

The application of TPU protective film is still relatively wide, such as: it was used as a keyboard protective film earlier. Now more used in mobile phone screens, computer screens and so on. Today we mainly talk about the application of TPU protective film on the screen of mobile phones and electronic products.

The difference between tempered film and TPU hydrocoagulation film

We all know that the mobile phone film is generally more advocate or prefer to stick tempered glass film, because compared with TPU protective film, tempered glass film's anti-smash screen, hydrophobic anti-oil (after fingerprint oil smeared), appearance, feel are better than TPU film, but there are still many businesses will choose TPU protective film factory, why! All things have its advantages and disadvantages, tempered film also has shortcomings, 3D tempered film on the surface of the curved glass effect is not as good as TPU film.

3D edge glue tempered film, that is, glue is applied around the glass to make it stick to the screen, but because the middle is not coated with glue, so the viscosity is insufficient, generally five or six days may fall off, the use of time is not long.

3D all-glue tempered film refers to the whole piece of glass coated with glue, so that it is better to stick the screen is not easy to fall, the disadvantage is difficult to stick, and prone to bubbles.

Mobile TPU protective film is more suitable for 3D curved screen mobile phones, easy to fit, not easy to have bubbles, and the price is cheaper than 3D tempered film, which is why businesses choose TPU protective film factories for 3D curved screens.

1, the material is not the same: hydrocoagulant film is a honeycomb structure, with super toughness of TPU material. Because its material is relatively soft, it can only play an anti-scratch role on the mobile phone screen, and there is no anti-fall buffer effect; The tempered film is made of tempered glass.

2, the scope of application is not the same: hydrocoagulant film is suitable for curved screen, because it is equivalent to a soft film, so it will not warp the edge, but hardness and wear resistance

3, the degree of fall resistance is different: the tempered film is more fall resistant than the hydrocoagulable film, which can prevent the glass panel from breaking and flying caused by the mobile phone accidentally hitting, and reduce the glass panel

4, in use, there may be water ripples affecting the appearance of the screen, and the tempered film has a higher picture transmittance.
