Mitsui Chemicals to set-up new production facilities for Glass Fiber Reinforced Polypropylene in Japan

Mitsui ChemicalMitsui Chemicals, Inc. announced that the joint venture Prime Polymer Co., Ltd. owned 65 percent by Mitsui Chemicals and 35 percent by Idemitsu Kosan Co., Ltd. is looking to set up new production facilities for the production of Mostron-L glass fiber reinforced polypropylene (GFPP).

The location will be the Anesaki Works (Ichihara, Chiba Prefecture) of Polymer Co., Ltd. The additional facilities at the new site will have a capacity of 3,500 tons per year and are tentatively scheduled to commence operations in September 2019.

Mostron-L, a Prime Polymer-developed composite material, is made by melting and mixing polypropylene (PP) resin with long glass fibers. The material below a specific gravity is suitable for lightweighting. Mostron-L also offers an attractive appearance with long glass fibers providing a good balance between hardness and impact resistance. The product is already being adopted in areas such as the unpainted insides of rear car doors.

Lightweight and electrification of automotive are driving to produce electric vehicles that are environmentally friendly. In view of the strict compliance with environmental regulations, the demand for fiber-reinforced resins is on the rise and is expected to grow further for such materials that can substitute for metal. Mitsui Chemicals Group is motivated due to this change in the scenario to establish its own manufacturing technology in this realm and work toward mass production.

Prime Polymer is moving forward with Mostron-L as a strategic product and is working to further reinforce and expand its business for the product.
