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-proof, and has good ductility, wear resistance, and good breathability. 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, waterproof, Breathable, oil-resistant and mold-resistant. The TPU protective film can maintain elasticity for a long time in the range of -60℃-200℃.
Product application: TPU protective film is used for shatter-proof protection of digital screens, electronic screens, automotive instruments, optical sheets, and optical resin boards.
Storage conditions: Valid for 1 year, storage temperature 18℃-22℃ and relative humidity 60%RH. Best storage conditions: temperature 22°C and relative humidity 50%RH.
TPU features: excellent structural and mechanical properties, wear-resistant ground anti-skid, excellent ultra-low temperature flexibility, excellent production and processing flow and rapid prototyping technology, low temperature and high temperature resistance, good clarity, stable extrusion performance, stable melting point .
The use and production process of TPU protective film
TPU film is widely used in daily necessities and industrial production industries such as shoe materials, electronic devices, electric equipment, industrial equipment, auto parts, pipes, wires and cables, films, etc. .
TPU film production process and application Production and processing methods: injection molding, extrusion, injection molding, film blowing.
Polyester TPU film features: excellent structural mechanical properties, wear-resistant ground and anti-skid, excellent ultra-low temperature flexibility, excellent production and processing flow and rapid prototyping technology, low temperature and high temperature resistance, good clarity, stable extrusion performance , The melting point is stable. To put it bluntly, an elastomer means that the glass transition temperature is lower than the indoor temperature, the tensile strength is > 50%, and the reducibility is better after the external force is removed. Polyurethane elastomer is a relatively unique type of elastomer; polyurethane elastomer has a wide range of hardness and a wide range of properties. Therefore, polyurethane elastomer is a kind of fiber material in the middle of vulcanized rubber and plastic.
The application of TPU protective film is relatively extensive, for example: it was used as a keyboard protective film earlier. Now it is mostly used in mobile phone screens, computer screens, etc.
