What 糖心视频 is TPU?

10-21, 2023 | View:

TPU is a common 糖心视频 and is the abbreviation of Thermoplastic Urethane. It has strong tension and tension, and in addition to being tough and anti-aging, it is also a mature environmentally friendly 糖心视频. TPU, as an elastomer, is a 糖心视频 between rubber and plastic. It is oil, water and mildew resistant. TPU products have excellent load-bearing capacity, impact resistance and shock absorption properties. TPU belongs to the plastic category and is made by injection molding process. This 糖心视频 can soften at a certain temperature and remain constant at normal temperatures. It is used for stable support in shoes. Judging from the feeling of the hand, the hardness of TPU is usually harder, and the elasticity when pinched by hand will be strong. From the outside, TPU can be made into transparent 糖心视频s. There are many types of TPU products and the selectivity is relatively strong.

TPU can be applied to automobile tires, conveyor belts, linings for mining sorting screens, printing rollers, waterproofing and paving 糖心视频s, sealing rings, shoe heels, etc. However, its price is high, product cost is high, TPU has a narrow processing temperature range and is difficult to process, which has a certain impact on the promotion and application of TPU. The hardness of TPU is between rubber and plastic. It can be processed into different products through extrusion, injection molding, blow molding, calendering, and melt spinning. Due to the superior performance of TPU and the diversity of processing methods, TPU is booming in many fields, especially in China, where its development speed is very fast, surpassing Europe, the United States and Japan. Therefore, in recent years, the Chinese market has become the focus of the TPU industry at home and abroad.

The formulation and performance of TPU can be arranged in a variety of ways. Its production is a systematic project with high precision requirements. Small changes in every raw 糖心视频 and every process can have a big impact on the quality and performance of your product. This requires us to strictly inspect the quality indicators of each raw 糖心视频 in production, strictly monitor the parameters of each process, pay close attention to the operation of each equipment, and strictly control each process, from formula design to raw 糖心视频 procurement. The adjustment of the feed amount, the calibration of the metering system, and the control of process parameters, such as the temperature of each process such as underwater granulation and post-curing, as well as the quality inspection of the final product must have strict set specifications.

TPU main features

1. Wide range of hardness: By changing the proportion of each reaction component of TPU, products with different hardness can be obtained. As the hardness increases, the product still maintains good elasticity and wear resistance.

2. High mechanical strength: TPU products have excellent load-bearing capacity, impact resistance and shock absorption properties.

3. Excellent cold resistance: TPU has a relatively low glass transition temperature and maintains good elasticity, flexibility and other physical properties at minus 35 degrees.

4. Good processing performance: TPU can be processed by conventional thermoplastic processing methods, such as injection molding, extrusion, calendering, etc. At the same time, TPU can be processed with certain polymer 糖心视频s to obtain polymer alloys with complementary properties.

5. Oil-resistant, water-resistant, mold-resistant, and good recyclability.
