1 thought on “How does TPU and PVC and Plastics define and how to distinguish it?”

  1. The TPU (thermoplastic polyurethane) has risen, and PVC artificial leather as the first -generation PVC artificial leather of artificial leather products. With its approximation of natural leather, the appearance is bright, soft, wear -resistant, fold -resistant, acid -alkali and other characteristics. From the 1970s in the 1970s Since the beginning of development, there has been a considerable scale, but due to the shortcomings such as its breathability and poor hygroscopicity, development has been limited in recent years. The advent of artificial leather -ultra -fine fiber leather has pushed the development of artificial leather to a higher -end new level. PVC artificial leather is gradually replacing the market position because of its disadvantages and backwardness of performance.

    In recent years, humans have paid more and more attention to environmental protection after realizing the harm caused by the destruction of the environment. PVC is very harmful to human health and the environment, and has also aroused the attention of international environmental protection organizations and relevant persons to PVC. Because PVC will release the toxic two evil English during the production process, and PVC products will have a certain carcinogenic effect on the human body, and the recycling and utilization of PVC is also very difficult. Therefore, in recent years, some people in Europe and cities in Europe Continuously putting pressure on the government has enabled some countries to take policies to restrict the use of PVC products, such as: the Netherlands has banned PVCs for packaging; Belgium has levied "ecological tax" for PVC mineral water bottle.

    In the past two years, the development of TPU (thermoplastic polyurethane) has brought great impact on the development of PVC artificial leather. Compared with PVC, TPU (thermoplastic polyurethane) It is more popular with people. At present, where the PVC is used, TPU (thermoplastic polyurethane) can become a substitute. But the advantages of TPU, PVC is not able to reach. The TPU not only has the characteristics of excellent tension, high tension, strong toughness and aging resistance. And it is a mature environmental protection material .TPU (thermoplastic polyurethane) has been widely used in: shoe materials, clothing, inflatable toys, water and underwater motion equipment, medical equipment, fitness equipment, automobiles, umbrellas, suitcases, suitcases , Leather bag, etc.

    The a few days ago, the state's "Promoting Industrial Structure Adjustment, Interim Regulations" and "Industrial Structure Adjustment, Guidance Catalog" were officially released. Direction and focus. In adjustment of the division of the guidance directory, energy consumption and environmental protection have become important criteria for industry division. Among them, the "Guidance Catalog" is divided into, encouraging, restricted and elimination. Polyethylene ordinary artificial leather production line is restricting the class. The restrictions mainly refer to the products that are backward and do not meet the conditions of industry access. It is not conducive to the optimization and upgrading of the industrial structure. For restricted projects, investment will be prohibited. For existing production capacity, enterprises are allowed to take measures to transform and upgrade within a certain period of time.

    In see that environmental protection and health have become the theme of human concern today, the harm of the PVC artificial revolution to the environment will gradually be eliminated, and the development space of TPU (thermoplastic polyurethane) will gradually expand and synthesize the synthesis The development of the leather industry must also continue to develop and healthy only in the direction of environmental protection.
