PU product classification

Polyurethane products mainly include the following types: foam plastics, elastomers, fiber plastics, fibers, leather shoe resins, coatings, adhesives and sealants, among which foam plastics account for the largest proportion. 

Polyurethane foam

Polyurethane foam is divided into two types: hard foam and soft foam. It has excellent elasticity, elongation, compressive strength and flexibility, as well as good chemical stability. In addition, polyurethane foam also has excellent processability, adhesiveness, heat insulation and other properties, and is a cushioning material with excellent performance. 

The production of polyurethane materials has spread throughout North America. It is reported that the overall average annual growth rate of the North American polyurethane foam market is expected to reach about 6%. It is estimated that by 2020, the growth areas are mainly concentrated in the residential and industrial spray polyurethane foam application market, as well as military applications. In addition, polyurethane will also be used in the medical industry to treat wounds in a timely and effective manner. 

Polyurethane elastomer

Polyurethane elastomer has a soft and hard two-segment structure, so through the design of the molecular chain, it can give the material high strength, good toughness, wear resistance, oil resistance and other excellent properties. It is called "wear-resistant rubber" polyurethane At the same time, it has the high elasticity of rubber and the rigidity of plastic. 

In the past year, due to the sharp drop in crude oil prices, under the background of the global economic depression, the year-on-year growth of my country's polyurethane elastomer market has been slower than in previous years. The imbalanced supply and demand ratio has led to the decline in the price of polyurethane elastomers. . But this phenomenon only appears in traditional polyurethane products. The market prospects of elastomer products with high technological content and innovation, such as nano-polyurethane elastomer materials, are still very impressive. 

Polyurethane fiber plastic

In 2015, the overall price of spandex market fell all the way, and the prices of spandex yarns of various specifications have fallen to the lowest point in history, and even set a new historical low. As of the end of 2015, the mainstream price of 40D spandex was as low as 36,000 yuan/t, a drop of 25.47% from the beginning of the year, creating a new historical low in the cycle. [4]

From the perspective of the upstream and downstream of the industry chain, the current situation of polyurethane fiber plastics is subject to the continued downturn of the economic environment. The downstream manufacturing sector is not prosperous in production and sales, and the supply exceeds demand, and the supply is severe. On the other hand, it is also due to raw materials. The price has fallen sharply.

The price of spandex has fallen all the way, leading to a decline in industry profits. The continuous release of new smart production capacity has caused oversupply, which has also severely impacted the spandex market. Coupled with the shortage of funds in the downstream industry of spandex, and the vicious circle of the industrial chain, my country's spandex imports plummeted from January to November 2015. The contradiction between supply and demand has become a flaw in the price of spandex.
