TESTRA®R Blasting Abrasive

Each blasting abrasive in our range has its own pro­perties and is the­r­efore sui­table for dif­ferent applications:

TESTRA®R is a calcium silicate-based blasting abrasive, com­pliant with DIN EN ISO 11126–6. It is cha­rac­te­rized by high abra­si­veness, con­sistent results, and envi­ron­men­tally fri­endly pro­perties. It meets occu­pa­tional safety requi­re­ments according to DGUV Rule 100–500 Chapter 2.24 “Work with Blasting Equipment (Blasting Work)”, making it a safe and tested blasting abrasive for indus­trial applications. 

This mineral single-use blasting abrasive is pro­duced from blast furnace slag, a mineral, liquid melt gene­rated during pig iron pro­duction. Due to its angular structure, high hardness, and stable com­po­sition, TESTRA®R offers excellent cleaning and coating removal performance. 

TESTRA®R is free of crystalline silica, and the dust gene­rated during blasting is not sili­co­genic. This makes it ideal for users who value safety, effi­ciency, and envi­ron­mental compatibility.

The calcium silicate blasting abrasive TESTRA®R com­bines envi­ron­mental fri­end­liness, ver­sa­tility, and cost-effec­­ti­­veness. These pro­perties are not simul­ta­neously offered by many other blasting abrasives. 

For those who value sus­tainable, clean, and repro­du­cible blasting results, TESTRA®R pro­vides a reliable and safe solution for a wide range of applications.

TESTRA®R is excel­lently suited for cleaning, coating removal, and pre­paring various sur­faces. Thanks to its angular structure and high abra­si­veness, it achieves precise, uniform, and repro­du­cible results, ideal for pro­fes­sional appli­ca­tions in indus­trial environments.

To achieve optimal blasting results, please select the appro­priate abrasive grit size. Finer grit sizes are sui­table for precise and faster work, while coarser grit sizes allow for greater material removal. 

Tip: The choice of grit size depends on the desired surface structure. As a rule of thumb, the largest grain of the sel­ected grit size mul­ti­plied by a factor of 3 yields the optimal nozzle dia­meter for the product.
