Thermoplastic Polyurethanes TPU
Thermoplastic polyurethane elastomer (TPU) is a type of elastomer that can be plasticized by heating and dissolved in solvents. It has excellent comprehensive properties such as high strength, high toughness, wear resistance, and oil resistance, and good processing performance. It is widely used in defense, medical, food and other industries.
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.

Some centrifugal or rotary vane pumps must add “water diversion†to form a closed environment in the pump cavity before the water is pumped. Then the pump can operate to form a negative pressure and achieve the purpose of water absorption. For example, the manual pump used in the past in the countryside. Pumps that do not have self-priming ability, it is troublesome to add "drainage" before each water absorption.
The level of the suction process is related to the power, flow rate, and structure of the pump. However, the self-priming suction process of the micro pump is not easy to do. For example, the self-priming suction process of the micro-pump BSP27160 can reach 4 meters. Even higher.
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.
What is a self-priming pump?
The meaning of self-priming is: under the condition that the pump suction pipe is air, the negative pressure (vacuum) formed by the pump is used, and the pressure below the pumping port is increased by the pressure of the atmospheric pressure, and then discharged from the discharge end of the pump. . This process does not require the addition of "water diversion (guided water)". A pump with this capability is called a "self-priming pump."
