Porous plastic material "Yamahachiporous" *Free samples available
Yamahachiporus
Coating ability, liquid absorption, moisture retention, low dust generation! A porous material with excellent functions such as "coating," "absorbing," "wiping," and "retaining."
The material with a three-dimensional mesh-like pore structure, where countless small spaces (pores) are connected and part of the walls between these spaces are open, is called "continuous porous material." Our product from Yamaha Chemical is based on plastic and features properties such as coatability, liquid absorption, moisture retention, and low dust generation. By combining the excellent functions of the material with our unique molding and processing technology, we realize porous materials tailored to customer needs. In particular, it excels in functions related to "coating," "absorbing," "wiping," and "retaining" for oils, chemicals, and inks! This is a functional porous material that incorporates shapes and functions that are difficult to achieve with conventional porous materials. 【10 Functions】 ■ Coatability ■ Liquid Absorption ■ Low Dust Generation ■ Chemical Resistance ■ Moisture Retention ■ Permeability ■ Hydrophobicity ■ Oleophilicity ■ Adsorption ■ Flexibility 【Unique Molding and Processing】 ■ Extrusion Molding / Injection Molding ■ Two-layer molding with different pore diameters (roll) ■ Secondary processing such as assembly processing and grinding processing ■ Surface treatment *For more details, please refer to the PDF document or feel free to contact us.

Company information
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.
