Sponges & performance process materials
We know maximizing performance is no small task.
That’s why we only provide materials with big impact.
Shima provides some of the most advanced process materials sourced exclusively from Japan to keep clean rooms sparkling, ensure extreme quality control in demanding manufacturing environments like semiconductor factories, and reduce errors and finishing times of industrial grinding processes.
Absorbent Sponge Rollers
-
Super-absorbent PVA rollers apply and control excessive fluid conditions, delivering the highest levels of performance to your production lines. With patented porous material in the form of a roller, PVA rollers provide the unsurpassed water absorbency and retaining properties of a PVA sponge.
-
Polyurethane rollers offer the same outstanding water absorbency and retention as PVA rollers. In addition to offering trouble free maintenance, Polyurethane rollers provide:
High heat resistance. Stable performance in an environment 100°-130° C, or in boiling water of 100° C.
Advanced flexibility. Soft and supple even when dry.
Stable towards salts. Can be used in alcohol or acids.
-
Polyolefin rollers offer the same outstanding absorbency and liquid retention as PVA rollers. In addition to offering trouble free maintenance, Polyolefin rollers provide:
Excellent chemical resistance. Can be used both with high concentration acidic or alkaline solutions.
Advanced flexibility. Soft and supple even when dry.
Lint free. Molecular structure ensures spotless applications.
High Performance Sponge Sheets
-
Specially formulated to absorb and manage liquids, Aion PVA materials are prized by a range of industries, from manufacturers of medical devices to hi-tech fields. Our patented Aion PVA sponges provide a range of grade differentiation, from finely controlled pore sizes to higher porosity. All Aion PVA sponges undergo stringent quality control testing to ensure that they provide:
Strong and supple structure - ideal for cleaning optical devices or precision instruments
High absorbency - can absorb up to as much as 1100% of its own dry weight.
Diverse applications -water absorption, retentive and wiping properties
Easy formatting - can be cut into desired shapes without expensive metal molds.
-
It is a special polyurethane sponge with a continuous pore structure that has fine texture, soft texture, excellent water absorption, water retention, and abrasion resistance, and is resistant to hydrolysis.
-
For even stronger acid or alkaline liquids than polyurethane sponges.
-
Made from PVA. Lint-free. No waste generated from use.
Highly absorbent. Continuous pores rapidly absorb high volumes of water.
Efficient at trapping dust. Micropores on surface create efficient surface area.
Economical. Washable and reusable.
Abrasive Papers & Grinding Stones
-
PVA stones combine the technical advantages of PVA with the integrity of precision grinding. These relatively softer stones tolerate both continuous grinding and high heat, and are ideal for grinding, polishing and finishing of copper cylinders.
-
Nikken is specialized in the manufacture of coated abrasives, crafted from carefully selected materials. The quality of their products is appreciated both in Japan and throughout the world.
Shima offers Nikken coated abrasives in many useful configurations including waterproof abrasive sheets, discs, belts, and rollers.
