In our long history, our company has accumulated rich production and application experiences, hence becoming the industry-leading enterprise. The high stability, security and good efficiency of our products are always recognized and highly praised by domestic and foreign users.

        In 1989, we set a precedent for industry standards in Thiourea Dioxide production, which marked the end of an era when no standards or criteria in TDO production is present. Being the main drafting unit, we have contributed to the three revisions of national standards of TDO, each in 1989, 1999 and 2009.

        Our company was elected as the director of the National TDO and Relevant Industries Association in the year 2000 for our world-wide reputation and excellent product quality, shown our recognition by the industry peers. It also established our industrial leading position.

        Our Pulp Bleaching Agent occupies most shares of both domestic and foreign market for its perfect pre-sale and after-sale services. We are the stable supplier for many large paper-making enterprises.

        We are always keeping developing new products for years. The new products are pushed to the market one after another, including Strong Reductive Agent, Soda Ash Substitute, Hydrogen Peroxide, Reduction Clearing Agent, Scouring Agent, Polyetheramine, Desulfurizing Agent, Dicyandiamide and Thiourea etc.

        The Polyetheramine series products we developed recently can completely replace imports and fill the domestic gaps in this field with high quality and low price. Being the key component of spray Polyurea and RIM, these products have excellent tensile strength, abrasion resistance, and corrosion resistance, that can be widely used for primary structure protection of important concretes, steel structure etc. commonly found in high-speed railways, high-class floor, wind power generation composite blade materials and so on.

        Our company is located at the beautiful coastal city Yantai, which has well developed traffic, an accessible geographical location, all leading to convenient and quick export.
