Yuncheng Chemical Industrial Co., Ltd. has been specializing in manufacturing Nanometer Colloidal Calcium Carbonate, Precipitated Calcium Carbonate as well as Basic Magnesium Carbonate and Gymnastic Chalk & Powder under the fundamental management of “Good Customer Service”, “Superior and Consistent Product Quality”, “Reasonable Supply Price” and “Systematic & Swift Delivery” in Tainan, Taiwan since 1950. The total quantities of products are more than 30,000 tons per year. Except Taiwan, they are exported to Mainland China, Northeast-Asia, Southeast-Asia, U.S.A., Europe, Australia, South Africa etc.

Colloidal Calcium Carbonate and Precipitated Calcium Carbonate are widely used as reinforcing agent and filler in rubber, plastic, rubber/plastic foam products, electric cable & wire, tire, paint, ink, sealant, shoe, PU waterproof materials and general industries to increase tensile strength and cost down. Pai Ian Hua CC, CCR and DD are ultra-fine colloidal calcium carbonate treated with surface-active agents and their average particle sizes are 30-100 nm, called “nanometer-grade” calcium carbonate. Because of the superior and consistent quality, we have built up an excellent reputation among customers and have been the leader in the field for decades.

On the occasion that the whole world highly develops NANO-technique, YUNCHENG will enhance the potential of company based on well-established practical management style, abundant experience and the spirit of pursuing innovative ideas.
