Thermoplastic Polyurethane (TPU) is a type of polymer resin that is known for its flexibility, durability, and versatility. It is a thermoplastic material, which means it can be melted and reprocessed multiple times without losing its original properties.
TPU is commonly used in various industries, including automotive, electronics, footwear, and sportswear. It is often used to make products such as phone cases, cables, hoses, seals, gaskets, and inflatable structures.
Some key properties of TPU include:
1. Flexibility: TPU has excellent flexibility, allowing it to bend and stretch without breaking. This makes it suitable for applications where flexibility is required, such as in shoe soles or flexible electronic components.
2. Abrasion resistance: TPU has good resistance to abrasion, making it suitable for applications that require durability and resistance to wear and tear.
3. Chemical resistance: TPU is resistant to many chemicals, including oils, solvents, and greases. This makes it suitable for applications where exposure to chemicals is expected.
4. Weather resistance: TPU has good weather resistance, meaning it can withstand exposure to sunlight, moisture, and extreme temperatures without degrading or losing its properties.
5. Adhesion: TPU has good adhesion to various substrates, allowing it to be easily bonded or laminated with other materials.
Overall, TPU is a versatile material that offers a balance of flexibility, durability, and chemical resistance, making it suitable for a wide range of applications.

[ China Agricultural Machinery Industry News ] In 2017, the Yecao Innovation Team focused on the mechanical demonstration of the mechanical equipment in the first five years of the leaf industry , and focused on the mechanical linkage of the key aspects of the mechanized production of lettuce, gradually forming lettuce from seedlings and filming. Matching mode of mechanized operation such as land preparation and transplanting.
The supporting mode of key links in the production of lettuce is gradually formed
On February 13th, team technicians went to Tongzhou Yongsheng Garden to carry out production trials of lettuce breeding. Yongsheng Garden is mainly based on planting lettuce. Because the lettuce seeds are flat, small and light, the requirements for mechanized seedlings are high. After the pre-screening, the seedling test uses the NS-30 semi-automatic small tray seeder. Assessment of job quality and operational efficiency.
The planter uses high-pressure gas as the power, manually swings and collects the tray, automatically completes the punching and sowing, and is especially suitable for factory seedlings. In the next step, the team technicians will conduct data analysis based on the test records, study the effects of different specifications on the seedling growth, and provide hand-based data for the mechanized integrated mode test of lettuce production.
