Solving the challenges of difficult porous material development! A new porous material that adds novelty.
For applications such as oil and ink coatings! We also accommodate complex shapes and micro-dispensing functions that are difficult with general porous materials.
Our company manufactures a continuous porous plastic called "Yamahachi Porous," which is characterized by its basic functions of liquid absorption, retention (storage and impregnation), and application (liquid supply). The standard material is hydrophobic and exhibits excellent functionality for absorbing, retaining, and applying inks and oils, allowing for optimal control of the application amount without dripping. It can also be optionally hydrophilized. We accommodate not only sheets and cylindrical shapes but also special shapes such as comb-like continuous protrusions used in hair care applications, as well as hollow shapes, which are difficult to achieve with conventional porous materials. Additionally, we can partially process the surface to impart the function of applying small amounts of liquid to objects in a patterned manner.

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.
