Low embrittlement Temperature Polycarbonate Frozen Sand Plastic Media PC 20-150 for Deburring

1. Product Description of Polycarbonate Frozen Sand Plastic Media PC 20-150

The polycarbonate abrasive is also called as PC Sand, Frozen sand, it is one cylindrical plastic particles made

by special formula PC monofilament.

Different from PA nylon sand, PC frozen sand has the outstanding characteristics of Low embrittlement

temperature,it can be used under -120 °C.

2. Main Specification ofPolycarbonate Frozen Sand PC 20-150

3. Main Applications of Frozen Sand:

Cleaning for Epoxy optical camera mirror,molds;

Deburing for the surface of aluminum alloy workpieces, aluminum-plastic inlaid workpieces etc;

Paint-removal for aircraft,high-speed rail,yacht as well as automotives;

Spilled glue-removal of resin package for the precision electronic components and plastic parts.

4. How Frozen sand remove the burrs under -120 °C?

As we know, polymer materials such as rubber, plastics and alloys will be in different phase states at different

temperatures, and will become brittle according to different thicknesses.

Then the overflow edge will brittle firstly, the workpieces will brittle later,during that brittle time gap, the overflow

edge will be removed through the impact and vibration easily.

And Frozen sand has the characteristic of Low embrittlement temperature, it is one ideal blasting material under

low-temperatute. The above principle is also available for Frozen sand.
