Yamahach Chemical Co., Ltd. Company Profile
Connecting needs and products through manufacturing! Achieving efficient support that becomes a solution for our customers.
We are a manufacturer of industrial porous materials that utilize "Yamahachi Porous"—a continuous porous plastic—to enable functions such as application, liquid absorption, and wiping. Leveraging our core manufacturing technology for "Yamahachi Porous" (a continuous porous material), we manufacture and sell products while also providing development support to our customers. We began by serving the stationery and stamping markets with products like porous pen tips, pre-inked stamps, and stamp materials. Today, we focus on industrial porous materials—such as porous sheets, rollers, tips, and sponge swabs—that utilize ten basic functions, including application, wiping, and liquid absorption. By combining these ten basic functions with seven proprietary processing technologies, we solve customer challenges and deliver optimal porous materials tailored to specific applications, shapes, and performance requirements. We also meet requirements that cannot be satisfied by standard products, thanks to our unique processing technologies and integrated production system.

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.
