Ming Dih Industry Co.,Ltd. was established in 1986. The objective of our EPS (Expandable Polystyrene) raw material is to be produced and used with advanced technological products, industrial products, and packaging for general consumer products. Also the materials are used in building construction as well. Therefore there's an extensive variety of usage available for this particular material. Our company is consistently developing new formulas to improve the quality and creating new materials in order to be more of a competitive company in the market of the same material. We distribute our materials worldwide to countries like America, Australia, China, Europe, Middle East and South East Asia. Our production volume has increased dramatically over the period due to high demand where we generated a volume of 160,000 tons p.a. In Taiwan there are six companies competing on the same material, where our production and distribution volume is one of the highest in our field. With in regards to exporting our materials overseas, we realise we had high demand and had consumers requesting for fire resistant materials, therefore we were one of the first companies to develop and also able to export advanced materials to consumers overseas. With this fire resistant material that we developed, it has also met the requirements and was awarded the UL94 HF-1 American Standards. Not only that we have met international standards with this material, we have continued to become an international company providing EPS worldwide.
