First, the selection of TPU materials. There are many kinds of TPU materials, such as Japanese materials, Taiwan materials, Bayer, and BASF. According to user needs and actual production, choose the right one.

Second, granulation and baking before production. The process of granulation and baking before production should also be paid attention to, which can reduce the occurrence of problems such as foaming and impurities during the production process.

Third, the control of temperature and production speed during the production process. Temperatures include die temperature and pinch temperature. The production speed should pay attention to the extrusion speed and winding speed of the die material.

TPU cast film production line equipment features: compact equipment, superior performance, screw and barrel optimized design, the machine has the advantages of uniform plasticization, stable extrusion, high output and long life. Reasonable material quantity configuration makes the whole machine small in power and consumes less energy. The hydraulic system is designed to be more reliable and quicker. All electrical boxes are fixed to the rack for easier transportation and installation, easier wiring and fewer failures. The extruder is made of special high temperature corrosion resistant steel. For the particularity of the material, the TPU cast film production line is specially designed for the structure of the screw, the die structure and the special shaped T-die are designed with special double-throttle design. The film thickness is high and the speed is more accurate. The screw adopts special mixing function and high plasticizing capacity design, which makes the pellets melt and the uniform color extrusion increases. The temperature control adopts advanced automatic control system, which can accurately control the plasticizing process, adjust the film thickness and flatness. The heat-sealability of the extruded cast film is good when it is heated, and it is favorable for heat-sealing the bag. Our machines can produce high quality membranes with low cost, high productivity, stable operation, uniform film, low waste, and low energy assumptions.

The combination of TPU (polyurethane elastomer) film and TPU film and substrate is a new environmentally friendly plastic product newly introduced in the international market in recent years. Due to its superior performance and environmental protection concept (material buried in the soil, affected by environmental temperature and microbes, and automatically degraded within 3-5 years), it is increasingly used in various industries and daily necessities. The market prospect is very broad and there is a huge market. Application potential.

What is a TPU cast film?

TPU film is a film product made of TPU material as the main raw material. It is a new type of high performance environmentally friendly film material with high strength, good toughness, cold resistance, oil resistance, aging resistance, weather resistance, environmental protection, non-toxicity, decomposability, etc. Excellent characteristics. Due to its easy to use and diversified functions, TPU film has been rapidly developed in recent years, and is used in shoe materials, waterproof and moisture permeable clothing fabrics, food packaging, medical supplies, inflatable capsules, weapon packaging, tents, sports and leisure equipment, Wide range and unique applications in many fields such as toys and consumer daily necessities packaging

What is the use of TPU cast film?

1. Shoe material TPU is mainly used for shoe materials due to its excellent elasticity and wear resistance. Footwear products containing TPU are much superior in terms of wearing comfort than ordinary footwear products. Therefore, they are widely used in high-end footwear products, especially some sports shoes and casual shoes.

2. Thin film TPU is increasingly popular due to its superior performance and environmental protection concept. At present, wherever PVC is used, TPU can be a substitute for PVC. TPU film can be used not only to bond with various fabrics, but also to produce a clear and dimensionally stable product by vacuum thermoforming. With the continuous improvement of domestic environmental awareness, the application of TPU has become more and more extensive. Among them, the areas with faster speed increase: upper lining, thermal underwear, transparent underwear, transparent shoulder strap, elastic band and medical breathable tape.

3. Adhesive TPU adhesive is a type of polyurethane adhesive. The use of polyurethane adhesives in Europe and the United States has become quite common, especially in the use of footwear adhesives, almost exclusively using polyurethane adhesives. The use of TPU adhesives in China is obtained by dissolving TPU and then obtaining a polyurethane adhesive after processing. In the use of TPU adhesives, mainly in the four main regions of Guangdong, Fujian, Zhejiang and Shanghai.

4. Hose Because TPU hose has softness, good tensile strength, impact strength and high temperature resistance, TPU hoses are widely used in China for aircraft, tanks, automobiles, motorcycles, machine tools and other mechanical equipment. Gas, oil hose. The main TPU hose manufacturing enterprises are concentrated in Guangdong, Zhejiang, Jiangsu, Shandong, Hebei and other places.

5. Wire TPU provides tear resistance, wear resistance and bending characteristics, and high temperature resistance is the key to cable performance. Therefore, in the Chinese market, high-end cables such as TPUs for control cables and power cables are used to protect coated materials for designing complex cables, and their use is becoming more widespread.

6. Roller polyurethane elastomer with its high mechanical strength, excellent wear resistance, excellent oil resistance, acid and alkali resistance, outstanding compression resistance and its application on the roller. The domestic roller mainly has the following types: industrial roller, household roller, sports equipment wheel, medical instrument wheel, toy wheel.

7. Plastic modification can be used for PA, ABS plasticization, but the cost is higher.

8. The main advantages of ink TPU ink are: excellent adhesion, low viscosity, good flex resistance, excellent wear resistance, high gloss, weather resistance, and can resist any sun exposure including UV irradiation. Excellent toughness and durability in a variety of applications. Aromatic and aliphatic TPU inks can be used in a variety of climatic and environmental conditions, with stable and outstanding performance. TPU ink has a smooth and smooth appearance, good light-shielding properties, alcohol resistance, strong adhesion, etc. It is mainly suitable for surface decoration of plastics such as TPU. Such as mobile phones, laptops, shoes, car leather chairs, sofas, high-grade leather goods, handbags, inflatable entertainment TPU products, umbrellas, raincoats and other TPU inks used on metal, glass, poor adhesion, easy to fall paint.
