Kumho Polychem is the Korea’s largest EPDM maker located in the Yeosu National Petrochemical Industry Complex. Starting with the newly built plant of 10,000-ton capacity in 1987 as well as through the 3rd expansion in which an ultralow temperature polymerization technology developed by the company was applied and with the construction and the operation of the 2nd plant in 2013, the company has grown to become the Asia’s largest and world’s 3rd largest EPDM maker with a 220,000-ton capacity per year. In addition, aiming to become the “world’s best EPDM maker,” the company will provide EPDM with the best prices through continuous expansion based on cost competitiveness, accumulated sales capabilities, and the upper hand in accessing the new markets in Asia.

KEPA is made by partially reforming EP(D)M properties through a process of grafting functional materials such as MAH(Maleic Anhydride) to EP(D)M. This leads to the improvement of its affinity with polar macromolecular compounds. It is used as an impact modifier and compatibilizer for polar resin.


KEPA

Various innoprene products supplied by Kumho Polychem Co.,Ltd. are thermoplastic elastomers of polyolefin type, and they can replace the existing thermosetting products of EP(D)M or CR rubber. The material is also able to replace soft PVC that is recently being discussed for its environmental problems. Moreover, the material is of low weight, therefore it is possible to develop light-weighted products.

Innoprene is a product that is already completely cross-linked and there is no need for an extra cross-link process before its ultimate use. Also, it is possible to simplify the processes and reduce the prime cost as it is an environment-friendly material allowing for an easy recycle of scraps resulted from processing.

Innoprene is possible to mold using devices of extrusion molding, injection molding, blow molding and calendar processing as in normal plastic resin. Especially, it is among the new materials that are possible to apply in extrusion area. (automobile glass run channel and construction window gasket etc)
