Hardness 70 Rockwell Plastic Media Blasting PC Granules Cylindrical Shape
Plastic blasting media PC frozen sand size PC 20-PC120 Frozen to Remove burrs
- Description
The main raw material of frozen sand is polycarbonate (PC), it is produced by one special formula PC monofilament through one high-speed precision pelletizer.
It is one blasting media, with the features of strong wear resistance and permanent antistatic as well as low embrittlement temperature, it can be used under -120 °C.
Due to its moderate hardness and machinability, the frozen sand can be efficiently polished without damaging the surface of the workpiece. It is one ideal low-temperature and normal-temperature blasting media.

- Main Features
1. Frozen sand has superior toughness, low embrittlement temperature. When rapid cooling by liquid nitrogen, the low temperature resistant frozen sand can easily remove the embrittlement, burrs and overflow glue that have been brittle earlier.
2. It is one ideal low-temperature and normal-temperature blasting media.
- Application
Frozen to Remove burrs, trim burrs, remove cape of Rubber moulded parts, plastic injection moulded parts, alloy die casted parts
Applicable Equipment of the PC frozen sand plastic media :
Liquid nitrogen frozen trimming sand blasting machine
