Synthetic Resins


Polypropylene is a plastic made by polymerizing propylene contained in combined gas in petroleum refinery. Since it is relatively inexpensive, lightweight and easy to process, polypropylene is used in a wide range of applications such as automobile components, home appliances, food packaging films, toys and general merchandise, and supports our lifestyles. Recently, in light of environmental issues, polypropylene has attracted attention for its characteristics such as superior recyclability to other materials and possibility of reuse.
The polypropylene business has been operated, since October 2003, by Japan Polypropylene Corporation, a joint venture between JNC and Japan Polychem Corporation (wholly-owned subsidiary of Mitsubishi Chemical Corporation).

High density polyethylene is polyethylene with density (specific gravity) of 0.94 or more, and is produced by polymerizing ethylene using a catalyst at a low pressure of several MPa to 4 MPa.
High density polyethylene has a wide range of uses such as plastic bag, containers for industrial chemicals and detergents, tarps, chemical fibers and non-woven fabrics, and supports our lifestyles.
Moreover, the business of high density polyethylene has been operated, since 1997, by Keiyo Polyethylene Co., Ltd., a sales joint venture between JNC and Maruzen Petrochemical Co., Ltd. For more information or inquiries, please contact us through Keiyo Polyethylene Co., Ltd.’s homepage.
