Jiaxing Huawen Chemical Co. Ltd., is a professional technology enterprises, engaged in research, product development, production and supply of styrene maleic anhydride SMA copolymers and new rare earth materials. It's the only manufacturer of SMA function resin in China, and also the first domestic enterprise with the aim to control the physical properties of rare earth materials . Howin has always focused on promoting technological innovation through special functional products and professional technical services to meet customers' differentiated demands.At present Products are divided into two major categories, one is SMA series and HW function resin series( produced by continuous bulk polymerization and extrusion reaction technology), which has been well received by the user at home and abroad. They mainly used as compatilizer or toughener of plastic alloy , heat resistant agents of engineering resins and alloy, and coupling agent of mineral reinforced resin.The other is new rare earth material, mainly used in the field of petrochemical catalyst, and it comes out first in China. Howin is committed to becoming an expert supplier of functional polymers. On June 6, 2017, new factory was completed and put into operation in Jiaxing, which owns a production capacity of 9000 tons of functional resin and 600 tons of rare earth catalyst per year. In future, we will develop and produce more products to meet customers' differentiated demands by our own research and assessment center, as well as the domestic and foreign universities, research institutions and other platforms, to achieve sustained innovation in the field of rare earth catalyst technology, functional polymerization of styrene and extrusion reaction technology of functional materials.
