100 mesh walnut shell abrasive powder for sandblasting

 

Description:

 

Walnut shell is developed and produced to lightweight filter material aiming at oily

sewage treatment. Raw material is based on superior quality thick pecan shell,

produced through degreasing, crushing, polishing, thermophilic digesting and many

times screening. It is yellowish-brown, not decay, without spot, and has high tenacity.  

 

Performance:

 

Walnut shell is used as an abrasive blast media similar to sand for cleaning, but without 

the negativities associated with other abrasive materials. In many typical cleaning appli

cations the substrate is metal, fiberglass, wood, plastic or stone. Walnut shell can be ut

ilized without scratching or pitting the substrate material / underlying surface. The walnut 

shell is ground to various sizes from coarse to extra fine depending the application. 

Walnut shell does not cause silicosis, a harmful lung condition associated with use of 

other blast media. Suggested Sizes are 12, 4/6, 12/20, 14/30, 18/40, 20/40, 40/60, 100
