Yamahachi Porous Sheet is an unique porous sheet material developed by our company. It is polyethylene-based and has features such as flexibility, venting, absorption, collectability, hydrophobicity, and low dust generation (lint-free).It can absorb liquids such as oil and ink, and is effective for application and absorption. We also provide custom-made optional processing such as double-layer molding and surface processing, depending on the customer’s physical properties and applications.
Flexible and does not damage the surface or workpiece

Kinds
Overview
Standard structure：Continuous porous structure connected in a three-dimensional network. The walls between the pores are open, providing vent and liquid permeability.
Double-layer ： Double layers of porous material with different pore sizes formed into a roller shape. The inner layer has a high porosity, and the surface layer has fine and dense pores.
Surface processing (partly) ：Partially processed porous surface in roll shape. Air/gass and liquid do not pass through the processed parts, but the unprocessed parts maintain their porous function with vent and peamiability. Detailed designs such as dot patterns can be processed on the surface, and functions such as applying a small amount of oil can also be added.
Surface processing (entirely) ： The entire surface is processed to seal the entire pores on the surface. The inner layer retains its porous function with features of vent and peamiability, and the processed surface layer does not allow ventilation or liquid to pass through.
