Yamahachi Chemical Co., LTD. Product Lineup

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.

Introducing the porous material "Porous Chip," which features chip shapes suitable for applications such as the application of liquids/solvents and liquid absorption. Made from polyethylene as the base material, it is characterized by flexibility, breathability, permeability, collectability, hydrophobicity, and low dust generation (lint-free). It has functions for retaining liquids, solvents, oils, and inks (reservoir), liquid application, and liquid adsorption, making it usable as functional components for various applications. We provide suitable processing tailored to customer needs through a consistent production system. Manufacturing through injection molding and assembly processing onto fiber cores is also possible. 【Features】 ■ Permeability and breathability ■ Hydrophobic (can be made hydrophilic) ■ Flexibility (hardness can be adjusted) ■ Collectability ■ Chemical resistance ■ Low dust generation *For more details, please refer to the PDF document or feel free to contact us.

From mold design to material blending and the molding and processing of porous materials! With a consistent in-house support system, we provide the molding and processing of porous materials that our customers need. If you are looking for porous materials with flexibility, breathability, permeability, and low dust generation in special shapes, please contact us!

Continuous porous roller material with a fine pore structure based on polyethylene! It features flexibility, permeability, and low dust generation, allowing liquids like oil to permeate. Ideal for coating applications! We provide optimal roll design and manufacturing tailored to customer development needs, including surface processing for precise application performance and special shapes or two-layer structures!

A polyethylene-based porous sheet with characteristics such as flexibility, permeability, breathability, low dust generation, and water repellency. It can absorb liquids like oil, retain them, and be applied to objects, as well as function in liquid absorption. We can also accommodate surface processing and two-layer molding according to the customer's development needs. Basically, it is produced on a made-to-order basis. Please contact us for more details.

What is coating? It is a technology aimed at "granting new functions, adhesion, and surface optimization," and the coating process in manufacturing is a crucial step that affects product quality. In the coating process within manufacturing, there are always challenges such as uneven application and dripping, which can lead to a decline in product quality and functionality. As a solution to these challenges, is the coating amount and method appropriate? Is there a need to aim for "micro-coating" that reduces the coating amount? Additionally, what are the methods and benefits?
