Schwandorf, 13 December 2011 - Sumitomo Chemical Co., Ltd. (“Sumitomo Chemical”) and Nabaltec AGof Germany have been in discussions about collaborating on their Alumina and Aluminum Trihydroxide(ATH) businesses. The companies have agreed to start collaborating first in the commercial area.
Beginning December 1, 2011, Nabaltec will be supplying Sumitomo Chemical an exclusive grade of fineprecipitated Aluminum Trihydroxide (ATH) for sale in East Asia.
Aluminum Trihydroxide (ATH) is most commonly used as a flame retardant additive in polymers for Wire &Cable, Printed Circuit Boards, and various building materials applications. As the demand for NonHalogen flame retardants containing products increase the use of Aluminum Trihydroxide (ATH) isexpected to see substantial growth. Europe has led the advancement and establishment of safety
standards preferring the use of Non-Halogen containing flame retardants, and is perceived as the global
standard.
Sumitomo Chemical manufactures fine precipitated Aluminum Trihyroxide (ATH) for thermoset resin
substrates and solid surface, low-soda Alumina for Liquid Crystal Display (LCD) glass, Integrated Circuit
substrates (IC), and automotive Spark Plugs, at its Ehime Works in Japan.
Sumitomo Chemical has expanded its production capacity for Aluminum Trihydroxide (ATH) over the pastyears, however with the rapidly increasing demand for ATH, Sumitomo decided to further enhance its
capability of meeting customer’s needs in a timely manner by securing additional supply of fineprecipitated ATH from Nabaltec AG. Nabaltec AG is one of the world’s leading specialized Alumina andATH manufacturers with operations in Europe and the United States.
Sumitomo Chemical will continue to explore additional areas of collaboration with Nabaltec AG, including
possible joint developments of new advanced inorganic materials. Sumitomo Chemical and Nabaltec AGagree the objective in this collaboration is to further strengthen their Alumina and Aluminum Trihydroxide(ATH) businesses.

Nabaltec AG, with registered office in Schwandorf, a chemicals business which has received multiple awards for innovativeness,
manufactures, develops and distributes highly specialized products based on aluminum hydroxide ("ATH") and aluminum oxide, as
well as other raw materials, on an industrial scale through its "Functional Fillers" and "Technical Ceramics" divisions. The company's
product range includes halogen-free flame retardant fillers and eco-friendly additives for the plastics industry. Flame retardant fillers
are used e.g. in cables in tunnels, airports, high-rise buildings and electronic devices, while additives replace stabilizers containing
heavy metals in PVC processing. Nabaltec also produces base materials for use in technical ceramics, the refractory industry andcatalysis. Unlike halogenated flame retardant fillers, the products manufactured by the company's "Functional Fillers" division containno hazardous substances and do not require separate disposal. Rather, the company's flame retardant fillers actually decrease thedevelopment of fumes hazardous to human health and the environment in the event of fire. Nabaltec maintains production sites inGermany and the US and plans to continue to consolidate its market position by expanding capacity, further optimizing processes
and quality and making strategic extensions to its product range. On the strength of its specialty products, the company strives toattain the market leadership in each segment.
