Plastics Pipes & couplings Aronkasei’s Piping Materials Business has grown in parallel with the popularization of vinyl chloride piping, and we have built up an extensive track record over more than half a century. Our small-diameter vinyl chloride chambers and manholes, developed from the seeds of original ideas, have greatly contributed to the expansion of Japan’s sewerage network. We have also developed small-diameter chambers and manholes for rainwater drainage. We now offer piping systems that provide effective removal of sewage and rainwater runoff covering all applications from single-family houses through condominiums and apartment buildings to large-scale facilities, as well as the construction and maintenance of full-scale sewers. Nursing care products Against the backdrop of a rapidly aging population, Aron Kasei manufactures and sells a variety of products for use in nursing care and human services situations. These products, based on the concept of “caring for people,” are designed to be safe, easy to use, and multifunctional. They include portable toilets, seats for use in bathrooms and other nursing care bathroom products, handrails and other home improvement goods, and products to help elderly people get about more easily, such as walkers and walking sticks. Elastomers Our AR Elastomer series are styrene thermoplastic elastomer compounds that have an elasticity close to that of rubber but can be molded as easily as general plastics and are thus suitable for injection molding, extrusion molding, and film molding. They can also be customized with a variety of value-added properties such as flame-retarding and vibration-suppressing capabilities. In 1951, Aronkasei Co., Ltd. became the first Japanese enterprise to launch rigid PVC piping products on the market, under the brand name Aron Pipe. Since then, Aron Kasei has leveraged its original monodukuri (excellence in manufacturing) capabilities to meet society’s needs, responding to new developments from one generation to the next. In addition to the plastics processing technologies we have developed and perfected over many years, we also deploy our staff’s expertise in the properties of materials, as well as their know-how required for the practical commercialization of products, enabling the Company to make important contributions to society in a wide field from daily life through infrastructure construction and maintenance to urban development. 18.2% Sales by Segment P18 0 20,000 30,000 10,000 0 800 1,600 1,200 400 600 1,400 1,000 200 10 11 12 10 11 12 26,978 1,279 (Millions of yen) (Millions of yen) Monodukuri Center PVC small-diameter chambers, manholes, Nursing care products AR Elastomers are highly-functional thermoplastic elastomers and rigid PVC pipes Toagosei Co., Ltd. 5
