Frozen Sand Polycarbonate Deflashing Plastic Media Blasting for O Seal Rings

1. Product Description of PC Frozen Sand

Frozen Sand Polycarbonate Deflashing Media for O Seal Rings

Frozen sand selects the imported high quality polycarbonate (PC) as material,then made into cylindrical

particles after being cut by one high-speed precision granulator; it has a very low embrittlement temperature

and can be used under -120℃. Frozen sand has the characteristics of precise dimensions, good toughness

and wear resistance, permanent antistatic.

2. Main Technical Data of Frozen Sand Polycarbonate Deflashing Media

3. Main Features of Frozen Sand

Appropriate hardness and machinability;

High polishing efficiency;

No damage to the treated workpieces;

One ideal blasting media under low-temperature and normal-temperature.

4. Main Applications of Frozen Sand Polycarbonate Deflashing Media

surface pretreatment of circuit boards and removal of spilled glue of electronic parts.

Clean the epoxy optical detector

Paint and coating removal from glass fiber, carbon fiber and resin workpieces.

Molds-cleaning for rubber, plastic, glass and die-casting,no damage to the accuracy of mold dimension

Aircraft paint removal, but retain the electroplating layer.

5. Why Frozen Sand can easily remove the deburrs of rubber,plastics,silica gel?

The burrs, overflow after injection molding or compression molding, in the surface of Plastics, rubber,

silica gel, elastomer aluminum-magnesium alloys is very difficult to remove with a general scraper,but

that above materials has the superior toughness and low embrittlement temperature.

So during rapid cooling with liquid nitrogen,that thinner burrs will quickly enter the embrittlement state,

which is cooling faster than the workpiece. At this time, sandblasting with low-temperature-resistant

frozen sand can easily remove these quicker embrittlement burrs and spilled glue.

That is why frozen sand is suitable toremove the burrs in low temperature and why it is called as frozen sand.
