TPU (Thermoplastic Polyurethane) is a kind of polymer material that combines the elasticity of rubber and the processing performance of plastics. It is divided into two major types: polyester and polyether. It also has the following characteristics:
Environmentally friendly and non-toxic: It can be recycled and meets environmental protection standards such as RoHS and REACH in the European Union.
Excellent elasticity: The elongation at break is as high as 500%-800%, and it is resistant to repeated stretching.
Abrasion resistance and corrosion resistance: The abrasion resistance is 3-5 times that of natural rubber.
Wide temperature range adaptability: The operating temperature range is from -40°C to 120°C.
Elasticity and flexibility: Suitable for dynamic environments (such as sports equipment, medical devices).
Waterproof and breathable: The microporous structure enables water vapor exchange, and it is used in outdoor clothing and footwear materials.
Strong weather resistance: It is resistant to ultraviolet rays and yellowing, extending the product's lifespan.
Good adhesion: It has excellent adhesion to substrates such as metals, fabrics, and plastics.
Global market: The market size exceeded 15 billion US dollars in 2023, and it is expected to exceed 25 billion US dollars in 2030, with a compound annual growth rate of 6.8% (Data source: Grand View Research).
Regional growth: The Asia-Pacific region accounts for more than 50%, and China is the world's largest producer and consumer.
Driving factors: New energy vehicles, wearable devices, and environmental protection policies (such as the plastic restriction order) drive the demand growth.
The TPU film production line of Jinwei Company adopts intelligent and high-precision processes, with the following core advantages:
Extrusion system:
The single-screw extruder realizes uniform plasticization of materials, with a temperature control accuracy of ±1°C.
High-quality mold steel, with a thickness deviation ≤ ±2%.
Casting/calendering process:
The air knife + vacuum adsorption technology ensures the flatness of the film.
The multi-roll calendering system rapidly cools to maintain the surface tension of the product.
Post-processing technology:
Online thickness measurement + tension closed-loop control, adjusting parameters in real time.
Corona treatment enhances surface adhesion to meet lamination requirements.
Energy-saving design:
The servo drive system saves more than 10% energy compared with traditional equipment.
The waste heat recovery technology reduces energy consumption costs.
