PVA market analysis——USA&CHINA

Polyvinyl Alcohol PVA is a sort of water —soluble macromolecule polymer.It has innocuity and biodegradation excellent performance ,and completely accord with modern society requirement to environment —protection product. Its water solution has good agglutinating value and film formation ;it could resist most of organic solvent such as oil,lube ,and hydrocarbon on ;it possesses chemical property such as etherify ,a etherify ,and contact Alde Hyde .It mainly used to manufacturing PVB ,oil —p roof pipe ,and Vinyl on fibred ;it also used as ad save for temporary protection fin and leather ,and use as glue feed for binding etc .China has already become maxim al P VA production capacity ,yield ,and consumption country .PVA production is almost balance account for world gross about 50 %
Application
Due to PVA excellent performance, is currently widely used in pharmaceutical preparations, with good results, mainly used in the following aspects:
1 ) as a release agent layer forming material ;
2 ) used as the matrix in Papua paste ;
3 ) as the matrix used in gel formulations ;
4 ) as the binder system of tablets , matrix material and the drug-loaded microspheres or microcapsules or dispersion medium containing porogen.

U.S. PVA market
In recent years, changes in alcohol consumption in general are not particularly large. , In 2009 consumption was l2.20 million tons, accounting for the world’s total consumption of polyvinyl alcohol 11.58%, representing a decrease of approximately 13.47%, of which PVB on polyvinyl alcohol consumption was 41,000 tons / year, accounting for 33.61 percent of total consumption is expected 2009-2014 polyvinyl alcohol consumption in the United States will average growth rate of approximately 4.90% to the total consumption in 2014 will reach about l5.50 million tons. PVB which average annual growth rate of demand for polyvinyl maximum will reach about 10.65% , followed by adhesives, demand will reach an annual growth rate of approximately 2.90 %, while in terms of textile pulp but the demand will average about 1.75 % of the speed reduction

China PVA market
China has become the world’s largest PVA production capacity and output, but also the largest consumption country, production of about 520 000 t / a, the basic balance demand, accounting for about 50% of the world total. But the current production of varieties is relatively simple, the majority of ordinary viscosity and alcohol sis of conventional products, mainly used in construction adhesives, low-grade textile pulp and other fields.
Currently particularly high or particularly low degree , low degree of alcohol sis fine and special varieties of high production technology no major breakthrough , such products market is dominated by Japan , the United States and other manufacturers possession. China’s economic development for the PVA new product development to provide a broad space for development. According to statistics, in 2007 PVA National Statistics actual production was 500,000 t, but the annual import volume is still about 40,000 t , while imports are high in this part of PVA fine and specialty products , expensive , lucrative one . Polyvinyl alcohol consumption since 2012 the situation is more optimistic. A long time in China’s economy will maintain rapid development ask the backdrop , PVA demand will maintain steady growth.

Film Formation of PVA

Polyvinyl alcohol is one of the few synthetic water-soluble high molecular polymers. Its indexes mainly include the degree of polymerization, the degree of alcoholysis and other special performance indicators. The main production process of PVA is: vinyl acetate is polymerized to form polyvinyl acetate, and then subjected to alcoholysis to form polyvinyl alcohol.

The PVA aqueous solution is easy to form a film, and the formed film is colorless and transparent, has good mechanical strength, and the surface is smooth and not sticky. The film is permeable to water vapor, but the permeability of gases such as hydrogen, oxygen, and carbon dioxide is very low, and the change in external temperature has little effect on the film.

Our company-BouLing Chemical Co., Limited specializes in the production of polyvinyl alcohol and other products, with a wide range of products and abundant supply. Our products are supplied to foreign markets and have a good reputation in foreign markets. If you are interested in cooperation, please contact us.

Advantages of polyvinyl alcohol

Polyvinyl alcohol BF-17 powder is a water-soluble and environmentally friendly macromolecule polymer, non-toxic and non-polluting binder, which is produced by acetylene method of calcium carbide, petroleum and natural gas with advanced technology and technology.

The series of products (polymer powder) can be dissolved directly in cold water.Pulverized polyvinyl alcohol (PVA) is added to paper making, beating and papermaking together with pulp, so as to produce paper with high strength. It is better to choose polyvinyl alcohol with higher average degree of polymerization.

Our company-BouLing Chemical Co., Limited specializes in the production and development of polyvinyl alcohol series products, if you need, you are welcome to contact us. Or you can choose to visit our company’s website, which contains detailed product information and company information.

Application of PVA BP17

Polyvinyl alcohol is a white or yellowish granule or powdery, stable, non-toxic water-soluble polymer. Polyvinyl alcohol has good film forming properties, and the formed film has excellent adhesion, solvent resistance, abrasion resistance, tensile strength and oxygen barrier property. Polyvinyl alcohol has both hydrophilic group and hydrophobic group. Therefore, polyvinyl alcohol has the property of interface activity, and can also be used as a protective colloid for polymer emulsification and suspension polymerization.

Among them, PVA BP-17 is suitable for sizing of staple fibers such as blended yarn, nylon, polyester and acetate. BP-17 can also be used in the production of construction glue and white latex, and its antifreeze performance is superior.

Our company-BouLing Chemical Co., Limited has mature scale in the field of polyvinyl alcohol, and the quality of our products can reassure our customers. If you want to know other products of our company, you are welcome to log in to our website.

Characteristics and application of water-soluble polyvinyl alcohol fiber

The polyvinyl alcohol water-soluble fiber is a fiber obtained by wet spinning, heat treatment, warm water curling, and oiling using polyvinyl alcohol as a raw material.The product has good physical and mechanical properties, corrosion resistance, acid and alkali resistance and good dry heat stability. The biggest feature is that it is soluble in water at a temperature of 86-95 °C.

The water-soluble polyvinyl alcohol fiber is blended with other fibers as an intermediate fiber, and the water-soluble polyvinyl alcohol fiber is dissolved after the textile processing, and a high-strength, light-weight high-grade pure wool fabric and a high-grade hemp fabric can be obtained.

The company’s-BouLing Chemical Co., Limited water-soluble PVA fiber products are mature in technology and stable in quality. Please feel free to purchase.
