Feature
Hardest:Its cutting ability is the most powerful among plastic grits. Its speed cleaning ability nears other sands.
Frequently used:Most widely applied. The use quantity of plastic grit sand is the biggest. Applied to various light cleaning in industry.
Durable:
Produced specifically for removing coating layers of painting on aluminum boards, glass fiber and compound material surfaces.
Low cutting ability:
At removing paint or spilt gel the workpiece surface will not be damaged. Easily gets cracked when the operating pressure is too high.
Soft and durable:
Provided with high impact-resisting strength with long use life.
Freeze-blasting:
When used in freeze-removing spilt gel, it has high impact-resisting strength with long use life. Also can be used in room temperatures.
Soft and no cutting ability:
Round ball-type is the least harmful for workpieces. Soft material with a particularly long use life.
Application
Substitutes glass beads and used in cleaning and hard material such as engine parts, turbine vanes and molds for cleaning and paint-clearing
The sand that is the fastest in paint-clearing of aircraft, trucks, trailers, trains, minivans, buses, and navy ships.
Blasting of aircraft frames, trucks, trailers, trains, minivans, buses and Navy ships
In paint-
clearing of CORVETTE
race cars and other compound material it will not damage the fine metal surface.
Used in cleaning of molds in semi-conductor processing.
In clearing of spilt gel of parts of bakelite category and semiconductor packaging as well as the
fine metal burr the workpiece surface will not be damaged.
In clearing of rubber and plastic spilt gel and of fine metal burr the workpiece surface will not be damaged.
In clearing of spilt gel of
LED semicon-ductor packaging parts the workpiece surface will not be damaged.

Advantage

Keeps the precision of tolerance in sizes for parts and instruments.
Holds electroplated layers.
Harmless for surfaces of soft metal or compound material workpieces.
Sand material can be recycled for use, reducing the expanse of sand.
Little abrasion for machines and instruments, reducing maintenance and repair expanses.
Unvolatile; no chemical poisonous material or smog.
 Incorrosive; no fear of change in remnant chemicals.
No silicon dust injury; will not cause silicosis.

Application

Spilt gel clearing for electronic industry: pretreatment of circuit board surfaces; spilt gel clearing of electronic parts.
Optical detector of cleaning epoxy resin: will not make the surface opaque.
Compound material: can clear paint on and coated layers of glass fiber, carbon fiber and resin workpieces.
Mold cleaning: can clean rubber, plastic, glass and die casts without compromising the precision of mold sizes.
Paint clearing of aircraft: clears most of aircraft paint but keep electroplated layers.
Ships: clears paint from hulls made from aluminum or glass fiber or wood. Can reveal and detect bubbles on glass fiber hulls.
Burr removing: removes fine and light burr without damaging workpiece surfaces.
Engine parts: easy clearing of amassed carbon and paint without damaging aluminum parts
Paint clearing vehicles: bodies of automobiles, trains, buses and trucks can be blasted with resin grits.
