Plastic is most strictly prohibited
A new round of guidelines on plastic pollution control came into effect on January 1, 2021. In a move that goes further than other restrictions, Shanghai has banned single-use plastic shopping bags from shopping malls, supermarkets and pharmacies, even if you have to pay for them. It is also known as the "No Plastic Order".
The greatest invention or the worst?
The problem of plastic waste on Earth is serious, and it is a serious threat to life on land and in the sea, but human society cannot give up the use of this material. In just over a hundred years, plastic has become a material that humans can't give up. In life, many things we use contain plastic components, such as TV, refrigerator, mobile phone, car, computer and so on are made up of ABS,PP,PVC,PC and other plastics, plastic in the field of materials has been unshakable status.
The change of materials and the development of science and technology are a double-edged sword. While plastic products bring great convenience to our life, they are also harming the ecological environment. Human use of a large amount of plastic products, the resulting plastic waste, if not properly treated, will lead to a large amount of plastic waste into the natural environment.
The fundamental problem with plastics is that they don't degrade. The United Nations Environment Programme estimates that eight million tons of plastic enters the oceans each year, the equivalent of a garbage truck full of plastic being dumped into the ocean every minute. Modern life we already can't leave the plastic, and protecting the environment is imperative, so now the plastic is strictly forbidden, by policy to guide people in daily life as far as possible to reduce the use of disposable plastic, in addition, reinforced plastics recycling and find more easily by the degradation of materials and chemical materials need to vigorously promote the important task.
Material revolution in TPU industry
In the automotive paint protective film industry, TPU as a more environmentally friendly material is gradually replacing the original PVC/TPH material made of automotive protective film.
General PVC resin prepared by suspension method, adding light stabilizer, UV absorbent, plasticizer and fillers and other modified mix granulation and then rolling or casting film.
Using oligomer polyol (soft segment), isocyanate and chain extender (hard segment) block and then granulated by extrusion film;
PVC and plasticizer are difficult to degrade and cause greater pollution to the environment. In addition:
PVC substrate is not weatherable, easy to turn yellow and dark, the service life is generally within 2.5 years
Plasticizer, the substrate becomes hard and brittle, after 3 years or so, it is very difficult to tear;
The plasticizer weakens the adhesive force between the glue and the substrate after falling out, and the residual glue is serious when tearing the film.
For owners, the yellowing of PVC film and the damage to the car paint may not be less than the damage to the environment pollution. Happily, under the impetus of market development, in recent years, the production of PVC car paint film has been greatly reduced, replaced by TPU car protective film because of its stable performance, tear resistance, yellowing resistance and other excellent performance and rapid development.
Although environmental pollution has become a world problem, but we in TPU kingdom, constantly develop more environmentally friendly green material in efforts to protect the environment, may the power of a single small enough to shake the rock, but as ordinary people, we can do is stick to every serious bit accumulation, because environmental protection is to protect ourselves.
Development of new materials
The company's business covers R&D, production and sales of high-tech new material TPU products. As a new high-tech environmental protection material, with a wide range of hardness, high mechanical strength, cold resistance, good air permeability, environmental degradation, oil resistance, water resistance and other excellent characteristics, widely used in automobile, electronics, wire and cable, pipe, shoes, food packaging and other industries and people's livelihood industries.
