AHWW Advanced Materials Technology Group was listed on the Shanghai Stock Exchange in 1997.
AHWW is an important new material manufacturer in China, with an annual output of 350,000 tons of polyvinyl alcohol (PVA), 40,000 tons of high-strength and high-modulus PVA fibers, 60,000 tons of polyester chips, 70,000 tons of VAE, 40,000 tons of PVB resin, The production capacity of 15,000 tons of PVB film and 5 million square meters of PVA optical film. The leading products PVA, high-strength and high-modulus PVA fiber have been ranked first in China and the forefront of the world for many years. Products such as PVA optical film, PVB resin and diaphragm are at the forefront of industry technology, and have been included in China's key scientific and technological research projects and national torch plan projects. The company has passed ISO9001, ISO14001, ISO45001 quality, environment, and occupational health and safety system certification.
PVA film is produced by AHWW's polyvinyl alcohol, which is the main raw material,with the technological process of dissolution, extruding, coating, drying film-forming, The biggest products has 1.6 meters wide, 30-75 microns thick, has a good mechanical , optical performance,Optical thin film with three cellulose acetate membrane membrane (TAC) compound, used for TN, the STN, TFT, LCD display and polarized glasses with polaroid manufacturing, water soluble film at low temperature can be used for hydrographics transfer printing, printing of plastic. Ceramic products' surface.
PVB interlayer translucent film, by polyvinyl butyral resin after plasticizer plasticizing extrusion forming of a kind of polymer material. Appearance as semi-transparent film,without impurities, with smooth surface, has a certain roughness and good softness, with inorganic glass has good adhesive power , transparent, heat-resistant, cold resistant, resistant to wet and mechanical strength higher characteristic,Is is the world manufacturing laminated, safety glass which widly used to be the best adhesive materials in building curtain wall, recruit, window, bank counter, prison tent out of Windows, and various kinds of bulletproof glass furnaces screen, and other areas of the building.
