Changes in pvc film with social development

The development of PVC film has reached a relatively high level. The reason why the development of polymers is so fast is mainly due to the promotion of social economy and the continuous increase of people's demand for materials.

????With the development of society, the advancement of science and technology and the improvement of people's living standards, organic polymer materials have developed rapidly, and their production is increasing year by year. According to statistics, the production of the world's three major synthetic materials (plastics, synthetic fibers and rubber) has reached 1.190, 0.1740 and 0.098 billion tons in 1995, and it is expected to increase to 1.4500, 0.2030 and 0.1158 billion tons by 2000 The average annual growth rate is 4.37%, 2.90% and 0.36%. Polymer materials have been widely used in the fields of construction materials, decorative materials, wires and cables, electronic appliances, information and transportation.

????Compared with metal materials and inorganic materials, due to the unique properties and good processing performance of organic polymer materials such as PVC films, it has been more and more widely used in various fields in the national economy and people's daily life And it beautifies and facilitates people's environment and life, and obtains significant economic and social benefits.
