Supply of extruded TPU sheets: the material revolution driven by green innovation empowers high-quality development of thousands of industries

In the wave of accelerated iteration of the global new material industry, extruded TPU sheets are becoming the "invisible engine" driving the transformation and upgrading of various industries with their unique performance advantages and wide application potential. This kind of board, which is composed of thermoplastic polyurethane elastomer (TPU) and other high-performance materials through a co-extrusion process, not only integrates the core characteristics of TPU such as high elasticity, wear resistance, and weather resistance, but also achieves "1+1>2" performance breakthroughs through multi-layer structure design, setting off a new revolution in material application in the fields of industrial manufacturing, new energy, people's consumption, and environmental engineering.

1. Technology iteration breaks through performance boundaries, and extruded TPU sheets become a “rigid need” for high-end manufacturing

In recent years, as co-extrusion technology continues to mature, the performance boundaries of extruded TPU sheets have continued to be broken through, providing unprecedented material solutions for the high-end manufacturing field. In traditional processes, it is often difficult for a single material to balance the contradictory requirements of "rigidity and flexibility" and "wear resistance and anti-corrosion". However, extruded TPU sheets achieve seamless integration of multi-layer structures by accurately controlling the melting state, extrusion speed and compounding ratio of different materials. For example, a "TPU + carbon fiber" co-extruded sheet developed by a new material company has a wear-resistant and scratch-resistant TPU layer on the surface, a lightweight and high-strength carbon fiber layer in the middle, and a chemical-resistant modified TPU layer on the bottom layer. This composite structure increases the impact strength of the sheet by more than 50%, reduces the weight by 30%, and has excellent acid and alkali resistance. It is widely used in shell parts of aerospace equipment, solving the pain point of traditional metal materials being "heavy and prone to corrosion."

In the field of precision manufacturing, the "microstructure molding" technology for extruded TPU sheets has shown unique advantages. By optimizing the flow channel design of the extrusion die, precision lines of 0.1 mm level can be formed on the surface of the sheet, which can not only enhance the friction of the material (such as anti-skid pedals for high-end machine tools), but also achieve efficient heat dissipation (such as heat dissipation back plates for electronic equipment). After an electronic equipment manufacturer introduced this extruded TPU sheet, the heat dissipation efficiency of the server cooling backplane it produced increased by 20%, and the operating temperature of the equipment dropped by 5-8°C, significantly extending the service life of core components.

2. The new energy industry has exploded, and TPU sheets have become the guardians of "green energy"

With the rapid development of the global new energy industry, extruded TPU sheets have become key materials in wind power, photovoltaic, energy storage and other fields due to their excellent insulation, aging resistance and environmental protection properties. In wind power equipment, the edge protection of wind turbine blades has long faced the double test of "high wind speed impact + ultraviolet aging". Traditional rubber materials often crack and fall off after 3-5 years. The blade protection strips made of extruded TPU sheets, through the composite structure of "TPU + weather-resistant polyolefin", can withstand the impact of strong winds of 50 meters per second, while maintaining stable performance in an environment of -40°C to 80°C, and extending the service life to more than 10 years. After application by a wind power company, the maintenance cost of a single wind turbine was reduced by 40%, and the stability of power generation increased by 15%.

In the photovoltaic industry, the dual characteristics of "light transmission + weather resistance" of extruded TPU sheets solve the packaging problem of photovoltaic modules. Traditional photovoltaic backsheets mostly use fluoroplastics, which have strong weather resistance but insufficient light transmittance. By adding special anti-UV additives, extruded TPU sheets can maintain a light transmittance of more than 90% while resisting yellowing caused by long-term exposure (yellowing index ≤ 3), and have excellent hydrolysis resistance. Even in rainy and humid southern areas, they can ensure the service life of photovoltaic modules for more than 25 years. According to industry data, the power generation efficiency of photovoltaic modules packaged with extruded TPU sheets is 3%-5% higher than that of traditional modules, which can create tens of millions of yuan more revenue for large photovoltaic power stations every year.

3. Innovative applications in the field of people’s livelihood, supplying extruded TPU sheets to reshape the experience of “food, clothing, housing and transportation”

The innovative application of extruded TPU sheets is quietly changing people's daily lives, bringing safer, more comfortable and environmentally friendly experiences in various fields of "food, clothing, housing and transportation". In the field of "living", the market of new building waterproof materials is being subverted by the supply of TPU boards. Traditional waterproofing materials such as asphalt membranes not only cause heavy pollution during the construction process, but are also prone to cracking due to temperature changes. The waterproof membrane made of extruded TPU sheets has a unique "micro-damage self-healing" ability through the co-extrusion structure of "TPU + self-healing rubber" - when the sheet is punctured and damaged below 0.5 mm, the molecular chain of the TPU material will automatically repair the gap under the action of temperature, achieving "watertight". After a high-end residential project adopted this waterproof membrane, the basement leakage rate dropped from 8% with traditional technology to less than 0.5%, and resident satisfaction increased to 98%.

In the "travel" field, extruded TPU sheets provide key support for the lightweight and safety of new energy vehicles. The battery pack casing of a new energy vehicle brand uses "TPU + flame-retardant PC" co-extruded sheets. It not only uses the elastic buffering performance of TPU to reduce the impact damage of the battery in a collision, but also reaches the UL94 V-0 level flame-retardant standard through the flame-retardant PC layer, solving the contradiction between "safety and lightweight". At the same time, the plate's high and low temperature resistance ensures that the battery pack can work stably in environments ranging from -30°C to 60°C, adapting to the use needs of different climate areas. Data shows that battery packs using extruded TPU sheets are 15% lighter and have an 8% increase in cruising range, and their safety scores in acupuncture and extrusion tests have reached the highest level in the industry.

4. Environmental protection attributes are highlighted, and extruded TPU sheets lead the new trend of "circular economy"

Driven by the "double carbon" goal, the environmentally friendly properties of extruded TPU sheets have become increasingly prominent, becoming an important carrier for the development of circular economy. On the one hand, among the raw materials for extruded TPU boards, the proportion of bio-based TPU is constantly increasing. By replacing traditional petroleum-based raw materials with plant-based raw materials such as corn starch and castor oil, carbon emissions can be reduced by more than 30%. The bio-based extruded TPU sheet produced by a company has a bio-based content of up to 50%. It has passed international sustainable development certification and is used to make degradable express packaging materials.
