The Development Status Of PET At Home And Abroad

Jan 21, 2018

PET (polyethylene terephthalate ester two) since 1953 by the DuPont Co to achieve industrialization, because of its good physical properties and processing of large industrial production, reduced costs reflected in the price advantage, quickly replaced the many other varieties of chemical fiber, and currently has become the largest family of synthetic fiber.

1, the development of PET in the world

Since 2003, the capacity of the global PET has expanded at an annual rate of about 9%. In 2005, the capacity of the world has reached about 54 million 700 thousand tons, and the output of 2005 is 41 million tons. According to PCi's prediction, by 2008, the global PET capacity will reach 67 million tons and the output is 50 million tons.

At present PET products from polyester staple fiber initially extended to polyester staple fiber, the polyester filament, polyester bottle, polyester film, non-woven fabrics, engineering plastics and composite multifunctional products such as a series of hundreds of thousands of product specifications, the products formed from the initial 100% short fiber the development of multi varieties of balanced development.

PET's large-scale industrialization in China started in the early 80s of last century, and its development is stronger than that in the middle of 90s. At present, its capacity has exceeded 20 million tons, becoming the largest country in PET world's production and consumption. The proportion of China's PET in the global PET is forecasted as follows.

2, the development status and trend of global non fiber PET

The use of non fiber PET first introduced by Kodak company is used as a substrate of photographic film, from the middle of 80s, the Coca Cola Co will be the introduction of varieties of beverage packaging, thereafter, non fiber use PET rapid development, has developed into the bottle, film, sheet, plastic, packing belt (strap). A field, only to food grade bottle with PET slice is mineral water, carbonated drinks, canned hot drinks, white wine bottles and beer bottle and other classification. The global PET capacity for packaging use in 2005 is 14 million 500 thousand tons, and its distribution is as follows:

China's packaging and non fiber use PET started late, but developed rapidly. In 2005, the production capacity of China's bottle PET reached 3 million 100 thousand tons, and the output reached 1 million 700 thousand tons, of which 1 million 200 thousand tons in domestic sales and 500 thousand tons for export. According to the current on Europe and the United States PET consumption (American 17KG/, European 20KG/ and PET) in the total capacity in the proportion of Chinese packaging applications PET production is still a large space for development (currently 1.3KG/), expects its growth rate should be in the 15%/ level, that is to say "" at the end of 11th Five-Year will be close to 650-700 tons / year production capacity.

Conclusion: the rapid growth of the use of one - time PET package brings new pressure to the environmental protection of China and the world. We often say a word, "waste together is garbage, waste is placed separately is resources." If we can make good use of the recycling and utilization of PET, we can not only reduce environmental pollution, but also provide new raw materials for human beings.
