Application advantages and production process analysis of TPU protective film


TPU protective film, short for Thermoplastic Polyurethane protective film, is a specialized material widely used for protecting surfaces in various industries. Known for its exceptional toughness, flexibility, and transparency, TPU protective film provides reliable safeguarding against scratches, abrasion, and impacts.

One of the key advantages of TPU protective film is its high level of resistance to wear and tear. It forms a durable barrier that shields surfaces from everyday damage, such as scratches from keys, objects, or rough handling. Whether it is protecting screens on electronic devices, automotive parts, or delicate surfaces in manufacturing processes, TPU film offers reliable and long-lasting protection.

Furthermore, TPU protective film is highly flexible, allowing it to conform to different shapes and contours with ease. This flexibility makes it ideal for applications that require precision fit, such as protecting curved surfaces or complex structures. Its ability to adhere securely to surfaces ensures that the film stays in place even under challenging conditions.

Despite its toughness and flexibility, TPU protective film maintains excellent transparency, allowing for clear visibility and display. Whether it is safeguarding the screens of smartphones, tablets, or touch-sensitive panels, the film does not compromise the visual clarity or touch sensitivity of the protected surface, providing an enhanced user experience.

Another notable feature of TPU protective film is its resistance to moisture, chemicals, and UV radiation. This makes it suitable for outdoor applications, where exposure to environmental elements could potentially damage surfaces. TPU film acts as a barrier against these factors, preserving the integrity and longevity of the protected materials.

In summary, TPU protective film is a versatile and reliable material that offers excellent protection for various surfaces. Its toughness, flexibility, transparency, and resistance to environmental factors make it an ideal choice for a wide range of industries, including electronics, automotive, manufacturing, and more. The use of TPU protective film ensures that surfaces remain pristine, extending the lifespan and maintaining the aesthetic appeal of the protected materials.


TPU protective film application advantages: 

Wide hardness coverage: By adjusting the allocation of various reactive groups in TPU, different hardness products can be obtained. With the increase in hardness, the product can still maintain stable flexibility and wear resistance.

High impact toughness: TPU products demonstrate high load-bearing capacity, impact resistance, shock absorption performance, acid and alkali resistance, moisture resistance, antibacterial properties, and resistance to yellowing.

Excellent drought resistance: TPU has a low glass transition temperature, allowing it to maintain stable flexibility even at -35°C, as well as its hair recoverability and other physical properties.

Good production and processing performance: TPU can be processed using commonly used thermosetting raw materials, such as injection molding, extrusion, injection, and laminating.

TPU classification: according to soft segment structure can be divided into polyester, polyether, and butenyl; According to the structure of hard segment, it can be divided into aminoester type and aminoester urea type.

According to the production and processing methods, it can be divided into injection grade and extrusion grade. Injection processing products include various transmission gears, hydraulic seals, fitness shoe soles, skiing shoes, power plugs, synchronous belts, etc. Key products of extrusion include wires, cables, fittings, pulse dampers, waterproof rolls, etc.

According to performance, it can be divided into polyester and polyether. Polyester type has good acid and alkali resistance, wear resistance, tensile and elongation performance, water resistance, and high temperature resistance. Polyether type has good water resistance, high toughness, high resilience, and excellent low-temperature performance. TPU materials can be widely used in footwear, electronics, clothing, defense, sports equipment, chemical products, baby products, civil engineering tools, and more.

Polyurethane TPU is widely used in daily necessities and industrial production due to its superior physical properties, operational performance, environmental protection, and applications in footwear, electronic devices, electric equipment, industrial machinery, automotive parts, pipes, wires, cables, films, and other products.

The production and processing methods for polyester-type TPU include injection molding, extrusion, injection, and blown film.

The characteristics of polyester-type TPU include excellent structural mechanical properties, wear-resistant and non-slip flooring, excellent ultra-low-temperature flexibility, good production and processing flow, fast molding technology, low-temperature and high-temperature resistance, good clarity, stable extrusion performance, and smooth melting point. Polyester-type TPU is used for shoe sole accessories, over-molding, blend modified materials, mobile phone protective covers, injection molded wheels, sports protectors, and mechanical equipment manufacturing. It is also used for films, pipes, wires, cables, conveyor belts, elastic cords, suspenders, air cushions, and shoe decorations.
