With the enhancement of global environmental awareness, PVC film as a widely used plastic material, its environmental performance has received more and more attention. Because of its wide application in many fields, such as construction, automotive, electronics and packaging, its environmental performance is not only related to the market competitiveness of the product, but also related to the sustainable development of human health and the environment.
Environmental problems of PVC film:
PVC film in the production and use process may produce harmful substances, such as plasticizer precipitation, combustion when the release of toxic gases, etc. These problems make the environmental performance of PVC film is questioned. In particular, Phthalates in plasticizers have become the focus of environmental groups and consumers because of their potential health risks and environmental impacts.
Environmental improvement of PVC film:
In order to improve the environmental performance of PVC film, the industry has taken a variety of measures:
1. Use environmentally friendly plasticizers: Develop and use non-phthalic plasticizers, such as TOTM (p-teroctyl benzoate), to reduce the harm to the human body and the environment.
2. Modification technology: By adding alkaline and neutral modified magnesium base type double hydroxide (PMgLaCe-LDH) and other environmental protection fillers, improve the overall performance of PVC film and reduce the release of toxic plasticizers.
3. Recycling: Improve the recovery rate of PVC film and reduce the impact of waste on the environment. Although there are technical and cost challenges in the recycling of PVC, its recycling rate can be increased by improving recycling technology and policy support.
4. Environmental standards: Follow strict environmental standards, such as the European Union RoHS directive, California Proposal 65, etc., to limit the content of harmful substances in PVC film.
Through the above improvement measures, the environmental performance of PVC film has been significantly improved, especially after the use of environmental plasticizers and modification technology, the environmental performance of PVC film has made a qualitative leap. The environmental performance of PVC film is a complex issue, involving many links such as the production, use and waste treatment of materials. Despite the challenges of PVC film in environmental protection, the environmental performance of PVC film has been significantly improved through technological innovation and environmental improvement. In the future, with the further development of environmental protection technology and the enhancement of environmental awareness, PVC film is expected to play a greater role in environmental protection and sustainable development. At the same time, consumers and enterprises should pay more attention to the environmental performance of products, choose environmentally friendly materials, and jointly promote the green development of the industry.
