Latest Patents
One of Maeda's significant inventions is a polyester elastomer resin composition that boasts excellent anti-noise properties and wear resistance. This composition achieves sustained wear resistance over an extended period, allowing lubricants to bleed out even in low-temperature environments, thereby maintaining their effectiveness. Additionally, it prevents lubricants from dissolving in water, even when molded articles are washed. The composition includes a polyester elastomer (A), an aliphatic amide compound (B), and a copolyether (C). The polyester elastomer (A) consists of a hard segment made from an aromatic dicarboxylic acid and an aliphatic and/or alicyclic diol, along with a soft segment selected from aliphatic polyethers, polyesters, or polycarbonates. The copolyether (C) contains two or more different types of alkylene units and has a number average molecular weight ranging from 1500 to 5000. The aliphatic amide compound (B) is present in an amount of 0.01 to 1 part by mass, while the copolyether (C) is included in an amount of 0.1 to 10 parts by mass, per 100 parts by mass of the polyester elastomer (A).
Another notable patent by Maeda is a polyester elastomer resin composition that exhibits excellent grease resistance. This invention comprises a thermoplastic polyester elastomer (A), a thickening agent (B), and a urea compound scavenger (C). The thermoplastic polyester elastomer (A) consists of a hard segment and a soft segment linked together. The hard segment is formed from a crystalline polyester derived from an aromatic dicarboxylic acid and an aliphatic and/or alicyclic diol, while the soft segment is selected from aliphatic polyethers, polyesters, or polycarbonates. The urea compound scavenger (C) has an amine value of 50 eq/t or more, and the thickening agent (B) is present
