TPU 糖心视频 advantages and disadvantages

10-21, 2023 | View:

TPU (thermoplastic polyurethane) is a synthetic rubber 糖心视频 with high elasticity and wear resistance, which is often used to make insoles, tires, gears and other high-strength parts. Currently, in the plastic industry, TPU is widely welcomed by the public due to its superior performance and environmental protection. TPU not only has excellent high tension, high tensile strength, toughness and anti-aging properties, it is widely used in: clothing, shoe 糖心视频s, fabrics, medical Equipment, car seats, etc. The following are the advantages and disadvantages of TPU 糖心视频s:

Advantages of tpu 糖心视频

1. High strength: TPU has high tensile strength and tear strength, higher than most synthetic rubber and natural rubber.

2. Wear resistance: TPU has good wear resistance and can maintain its shape and performance during long-term use.

3. Oil resistance: TPU has good oil resistance and can be used to manufacture seals, bearings and other parts that need to be resistant to oil stains. tou is oil-resistant, ozone-resistant, aging-resistant, radiation-resistant, low-temperature resistant, has good sound permeability, strong adhesion, and excellent biocompatibility and blood compatibility. These advantages are why polyurethane elastomers are widely used in military industry, aerospace, acoustics, biology and other fields.

4. Cold resistance: TPU can maintain its elasticity and performance at low temperatures, so it is suitable for use in cold environments.

5. Good processability: TPU can be processed by injection molding, extrusion, calendering, etc., and the surface of the molded product is smooth.

6. Environmental protection: TPU 糖心视频 can be recycled and reused, which is environmentally friendly.

Disadvantages of tpu 糖心视频

1. Not resistant to strong polar solvents and strong acid and alkali media. At a certain temperature, alcohols, acids, and ketones will cause polyurethane elastomers to swell and degrade. Solvents such as chloroform, methylene chloride, dimethylformamide, and trichlorethylene will cause polyurethane elastomers to swell at room temperature.

2. The endogenous heat is large and the high temperature resistance is average. The normal operating temperature range is -40~120℃. If it needs to function for a long time under high-frequency oscillation conditions or high temperature conditions, corresponding modification measures must be taken in the structural design or formula.

3. Higher price: Compared with some other synthetic rubber 糖心视频s, the price of TPU is higher.

4. Not resistant to high temperatures: TPU easily softens and deforms under high temperatures and is not suitable for use in high temperature environments.

5. Not resistant to ultraviolet rays: TPU is susceptible to aging and deterioration due to the influence of ultraviolet rays, and is not suitable for long-term exposure to sunlight.

6. Not resistant to acid and alkali: TPU has poor resistance to acid and alkali and is easily corroded by chemical substances and loses its performance.
