What Is Open-Cell Porous Plastic? Development Case Studies Vol.3
Applying, absorbing and stamping: 9 development cases using Yamahachi Porous, our open-cell porous plastic
"Yamahachi Chemical Development Case Studies Vol.3" introduces development projects using Yamahachi Porous, our open-cell porous plastic. It covers 9 projects for machinery makers, measuring and analytical instrument makers, an overseas writing instrument maker and others, in the fields of cleaning, coating, liquid retention, absorption, stamping and writing. Each case is explained in two parts: the challenge and the result. The catalog also shows how Yamahachi Porous differs from ordinary sponge, and its 10 basic functions. * Please download the PDF to see the case studies.

Applications/Examples of results
[Development track record] - Cleaning roller (picks up and absorbs excess oil and dirt) - Conductive coating part (conducts electricity through the liquid held in the pores; special protrusion shape) - Micro-coating part with surface patterns (dots, lines or logos designed as required) - IPA reservoir (high porosity to hold solvents such as IPA) - Ink absorbing pad (pores open only on the sides; adhesive tape applied) - High-precision marking tip (for lensmeters, other measuring instruments and recorders) - Marker nib (shape and ink flow matched to the customer's drawing) - Roller for privacy-protection stamps (two-layer structure for 50 m of continuous stamping) - High-precision material for pre-inked stamps (low-temperature processing, wear-resistant) For details, please see the catalog or contact us.

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.
