"Polyplus FPI" is used for the removal of coatings in the pre-treatment process of fluorescent penetrant testing, which helps to reduce the contamination of fluorescent substances that can interfere with the inspection, allowing for highly accurate testing. By producing it with 100% carefully selected materials sourced domestically in Japan, we can minimize quality differences caused by impurities and lot variations, making it safe to use. It is used for paint stripping from aluminum alloy equipment before fluorescent penetrant testing for aircraft, as well as for cleaning titanium alloy parts. [Features] - Removes only the coating - Achieves a contamination rate of fluorescent substances below 0.1% - Produced with 100% carefully selected materials sourced domestically in Japan - Suitable for pre-treatment in inspections *For more details, please refer to the PDF document or feel free to contact us.

Thermosetting resins are highly durable, heat-resistant, and chemical-resistant, making them widely used in household appliance parts, industrial parts, machine parts, tableware, outlets, and more. However, the biggest disadvantage of thermosetting resins is that, in contrast to thermoplastic resins, once they are molded by heat, they do not melt again when heated, making it difficult to remold them and unsuitable for recycling or reuse. However, U.S. Technology Co., Ltd. in the Far East recycles (upcycles) three types of thermosetting resins: urea resin, melamine resin, and unsaturated polyester resin, to manufacture and sell "resin-based abrasives" used for various applications such as paint stripping for aircraft, burr removal for electronic components, mold cleaning, and decoration. *For more details on the column, please refer to the related links.

Plastics can be broadly classified into two types based on their properties: thermoplastic resins and thermosetting resins. Thermoplastic resins liquefy upon heating without undergoing a chemical reaction and solidify upon cooling, forming linear chain polymers. In other words, thermoplastic resins become liquid at their glass transition temperature or melting point, and solidify again when below that temperature, allowing them to transition between liquid and solid states. A common analogy is that of cookies and chocolate: thermosetting resins are like cookies; once baked, they cannot be melted again in the oven, and while they may burn at high temperatures, they do not liquefy. On the other hand, thermoplastic resins, like chocolate, melt and change shape when heated to a certain temperature. *For more detailed information, please refer to the related links.

By using our Polyplus (urea resin), we can efficiently clean dirt and residues that cannot be removed by brushes stuck in grooves and recesses, without damaging the surface. If the workpiece is cast, it is possible to clean using either Polyplus (urea resin abrasive) or Type Three (melamine resin abrasive). We recommend selecting the abrasive based on the quality and surface condition you desire. Due to our unique production method, there is minimal variation between lots, allowing us to process any surface with the same quality. In particular, our long-time customers highly appreciate the "quality of the product that is evident upon use." We can provide samples, so please feel free to contact us if you have any interest.

We specialize in deburring electronic components such as capacitors, diodes, LEDs, transistors, inductors, and phototransistors, which require high-quality processing. We mainly use carefully selected domestic materials, and the quality of the abrasives is consistently uniform, allowing for stable processing without work damage. If abrasives get trapped in the terminal area, you can continue to use them by changing the material or particle size. Please give U.S.T.F.E.'s POLYMEDIA a try. *Types of burrs that can be removed (thin burrs, dam burrs, side burrs, gate burrs, resin flash, etc.) We offer options for dry blasting and wet blasting (liquid honing). Samples of abrasives are available.

For hard metals like cast iron, using Type 3 (melamine resin) with high cutting power allows for efficient cleaning. Using glass beads gradually cuts into the surface of the mold, causing edges and fine details to disappear with each cleaning, but Type 3 (melamine resin) can clean hard metals with minimal damage since it is a resin. Additionally, there is almost no damage to the blast machine body, nozzles, hoses, and other tools, which helps reduce maintenance costs. By switching from harmful and toxic organic solvents to abrasives for cleaning, it also contributes to improved safety for workers and better workplace conditions.

For hard metals like cast iron, using Type 3 (melamine resin) with high cutting power allows for efficient cleaning. Using glass beads gradually cuts into the mold surface, causing edges and fine details to disappear with each cleaning, but Type 3 (melamine resin), being a resin, can clean hard metals with minimal damage. This method is particularly effective for cleaning residual vulcanized material on mold surfaces during rubber vulcanization molding. Additionally, there is almost no damage to the blast machine body, nozzles, hoses, and other fixtures, which significantly reduces maintenance costs. By switching from harmful and toxic organic solvents to abrasives for cleaning, it also enhances worker safety and improves the workplace environment.

The surface condition of aluminum cans after processing varies depending on the type of resin used. 1. When using our product "Polyextra," it is possible to leave a glossy finish while only stripping the surface coating. This is a polishing material made of unsaturated polyester resin. 2. When using our product "Polyplus," the surface is lightly cut, resulting in a matte finish. It is possible to retain designs such as grooves and indentations. This is a polishing material made of urea resin (urea-formaldehyde resin). 3. When using our product "Type Three," the surface becomes matte. It allows for efficient and quick cleaning. This is a polishing material made of melamine resin. All photos show processing with polishing materials of size "#60-80 (325-180μm)," and the blasting conditions are standardized. In the case of thin aluminum, such as aluminum cans, alumina or glass beads can quickly create holes, but our resin-based polishing materials do not easily create holes. However, due to the way the blasting is applied, the aluminum may expand (stretch), so it is necessary to understand the physical properties of the blasting target and set the blasting conditions accordingly.

The α series is a new abrasive developed specifically for wet blasting (liquid honing), where glass beads are blended in a well-balanced manner with unsaturated polyester resin. It combines the two properties of glass beads and unsaturated polyester resin, excelling in fine processing while minimizing damage to the workpiece while maintaining cutting power. It is suitable as an alternative to other thermosetting resin abrasives and plant-based abrasives. In particular, plant-based abrasives (such as walnut, apricot, peach, etc.) can have variability in hardness and durability, requiring adjustments to blasting conditions depending on the batch. However, our resin-based abrasives maintain consistent quality, have low friability, and are durable, allowing for repeated use according to each application. All α series products are blended in-house, and we pay close attention to managing the particle size distribution after blending. Only abrasives that meet our strict standards are sold to our customers. *For more details, please refer to the PDF document or feel free to contact us.

The US series is an abrasive developed for POLYEXTRA's wet blast (liquid honing) using unsaturated polyester resin. Due to its specific gravity of 1.15 to 1.25, which is close to the weight of water, fine particle abrasives tend to float on the water's surface. However, thanks to our manufacturing technology, the abrasives in the US series minimize floating on the water's surface and can maximize their performance as abrasives. Additionally, the US series is softer than TYPE III and POLYPLUS, but harder than nylon. It is suitable as an alternative to abrasives of similar hardness or plant-based abrasives, which can have variability in hardness and durability, requiring adjustments to blasting conditions depending on the batch. In contrast, our resin-based abrasives maintain consistent quality, have low friability, and are durable, allowing for repeated use according to specific applications. *For more details, please refer to the PDF document or feel free to contact us.
