Our factory is an emerging technology-based private enterprise which was founded in 1993. In recent years, with the reform and opening up policy, our factory has become a star enterprise specialized in producing filter paper, from small to large, weak to strong. It is the first factory that adopt no spinning and weaving technique to produce super filter paper in China and the annual output of the “Wuhuan ”brand high-level filter paper is 7,000 tons.Filter paper using advanced technology and high-tech achievements, have excellent water resistance, oil resistance and curing properties, good toughness, high impact-resisting strength and fatigue resistance. The pressure ring strength, stiffness, tensile strength and other mechanical properties are much better in comparison with those of the similar products. The filter paper that our factory produces has good air permeability, good filter performance and high ash storage capacity and long useful life.
