Polyolefin Sponge
Porous material made from PE/EVA. Resistance to strong acid and strong alkali. Various application for absorption, liquid retaining, wiping, and filtration.
■Excellent chemical resistance. It's available to use under strong acid and strong alkali, also available to use under some oxidizing agent and organic solvent.
■Excellent absorption. It absorbs and retains solution because of its fine continuous pore structure.
■Because of sponge of integral structure, PO Sponge is free of any fray like nonwoven or felt.
■Because of its remarkable softness, PO Sponge Roller marvelously follows the contour of workpiece.
■Filtration & Absorption for gas and liquid
■Liquid Transfer
■Space for Electronic Parts
■Humid Coordination(Sublimation
■Ink Retainer & Supplier
■Wiping Material
