PVP (polyvinylpyrrolidone) is recognized as one of the synthetic compounds with good compatibility, low toxicity and physiological stability to humans and animals. PVP was originally invented as an artificial plasma substitute. PVP series products are widely used in daily chemical industry, pharmaceutical industry, brewing beverage industry, pigment and coating industry, textile industry, paper industry, petroleum production, photosensitive materials and electronics industry because of their excellent solubility, chemical stability, thickening, film forming, adhesion and adsorption capacity for hydrogen bond molecular groups.
Vinyl methyl ether/maleic anhydride copolymer (PVME/ maleic anhydride copolymer) without benzene/toluene solvent is a newly developed project. This product is a functional polymer independently developed by our company. Its physical and chemical properties are similar to those of PVP series products, and it is also non-toxic and harmless to human body. According to the molecular weight of reaction products, products can be divided into three categories: oligomer, polymer and polymer, and more than 20 varieties can be derived from these three categories of products. Because the physical and chemical characteristics of these two raw materials are very different, it is difficult to carry out polymerization. At present, only American ISP has large-scale production in the world, and it can only be carried out in benzene or toluene solvent. BASF Germany only produces a small number of low molecular weight products.
At present, the new open source has three Reppe acetylene production lines, covering NVP monomer, PVPK series (povidone), * * povidone and other VP/VA * * polymer series products, PVPP (cross-linked povidone), PVP-I complex (povidone iodine), 2- pyrrolidone and related pharmaceutical intermediates. At present, Xinkaiyuan is also the only enterprise capable of producing PVPK 12, PVP K60 and PVP K 120 powder in China, and the newly developed vinyl methyl ether/maleic anhydride (PVME/ MA) * * * polymer has reached the international leading level.
New open source has established a complete trademark system. Boxin brand food-grade PVPP, NKY, Kovidonetm, PolyKovidonetm, PolyFiltertm and Polyviscoltm are the trade names of different series products of our company.
New open source customers spread all over the world in more than 60 countries and regions, and established a relatively complete sales system in Europe, the United States, Japan, Australia, India and other places, which can not only provide customers with high-quality products, but also provide timely and thoughtful localization services.
