Over View: PA is widely used as phthalate plasticizer, unsaturated polyester resin, dye intermediate. PA manufacturing method is devided into ortho-xylene based process and naphthalene based process by used raw methrials and fixed-bed type and fluid-bed type by used catalyst.Since our subsidiary, Aekyung Industrial Co., Ltd. produced PA for the first time in Korea, Aekyung Petrochemical Co., Ltd. has developed into the world 's largest one as a single plant through the constant technology development and construction of new plants.
Our company's PA technology was internationally recognized and Aekyung Petrochemical Co.,LTD. has signed the reference plant contract to provide the latest catalyst with germany's wacker chemie Co.,Ltd. since 1995 Aekyung Petrochemical Co.,Ltd. has produced PA for over the past 30 years, based on its tradition and latest technology. Aekyung Petrochemical Co., Ltd. promises to supply high quality products at any time anywhere.
