According to customs statistics, China's imports of polypropylene have steadily declined in recent years, and the dependence on imports has been reduced year by year. In 2017, China's import dependence on PP was 18.1 %(see Figure 3). However, the structural imbalance between the supply and demand of polypropylene still exists, and the contradiction between the excess of general-purpose materials and the high dependence of high-end materials on imports will continue to coexist for a long time.

PTA futures have risen significantly in the past two days, coinciding with a week-long survey of companies involved in the PTA industry chain in Zhejiang province this week. The research object includes 1 large PTA production and chemical enterprises, 3 large chemical fiber production enterprises, more than 10 small and medium-sized chemical fiber production enterprises and textile city market. From the results of the survey of the companies visited, most companies believe that the polyester industry is currently in the boom cycle, and that multiple PTA futures are fundamentally supported.

With the rise of plastic steel, plastic wood and coal to change gas, coal to change electricity and other industries, we can expect that polyethylene in pipe, household products, industrial chemical packaging, food, pharmaceutical packaging, automotive components and other fields continue to grow.

Global polypropylene production capacity will continue to grow steadily over the next three years and is expected to increase to around 88.9 million tons per year by 2020, with an average annual increase of more than 3 million tons per year. The new PP devices are mainly concentrated in Asia, the Middle East and North America, among which the new production capacity in the Middle East and North America is concentrated around 2020; It remains the world's main source of new capacity.

Pressure-sensitive adhesives are widely used in electronic appliances and are mainly reflected in the following aspects.

Pressure-sensitive adhesive is a kind of adhesive that can be temporarily bonded by slightly applying pressure. Pressure sensitive adhesive is a kind of adhesive that makes adhesive tape. It is divided into solvent activation type, heating type and pressure sensitive type. Among them, the use of pressure sensitive type is the most convenient and the development is rapid.

At present, China's adhesive belt enterprises mainly rely on exports, most of the industry's adhesive belt business depends on exports to pull the market, the domestic adhesive belt factory operating rate has been reduced, the corresponding order has also declined, and adhesive enterprises affected by it is not very large.
