Yamahachi Chemical manufactures and sells products based on our core technology "Yamahachi Porous," an open-cell porous plastic, and supports our customers' product development. Starting in the writing-instrument and stamp fields—porous pen nibs, pre-inked stamps, and stamp foam materials—we now focus on industrial porous materials (sheets, rollers and sponge swabs) that leverage 10 basic functions such as application, wiping, and absorption. By combining these 10 basic functions with 7 proprietary processing technologies, we solve customer challenges and deliver optimized porous materials with the required use, shape, and performance—including requirements that standard products cannot meet, through our integrated in-house production.
