Envira Sponge blasting media / composite blasting media made of PU

For heavily cored surfaces and for removing elastomeric or extremely thick coatings. Cleans according to Sa 2,5 or Sa 3 standard. Not recommended for use in wet or humid environments. 

Surface roughness: 100-125µm

Removal of multilayer coatings on steel or when a rougher surface profile is required to the application of coatings. 

Surface roughness: 80-100µm

The first choice for many industrial applications. On Steel; rust and paint coatings are removed and a surface with Sa 2,5 or Sa 3 can be achieved. 

Surface roughness: 60-80µm

Removal of 1- or 2-layer coatings on steel or glass fibre or suitable for weld seam cleaning before coating. Removes light coatings from steel and aluminium or can be used to activate surfaces before painted. Cleans according to Sa 2. 5 or Sa 3 standard. This grade can also be used for the rehabilitation of concrete, stone and masonry. 

Surface roughness: 40-60µm

General purpose blasting medium with limited reusability. 

Surface roughness: 50-60μm

For more sensitive work on wood, masonry or concrete, as well as on steel for cleaning. Removes light coatings of steel and aluminum. Cleans to Sa 2,5 or Sa 3 standard. 

Surface roughness: 35-50μm

For selected coatings that require a slightly roughened profile. Removes light coatings from steel and aluminum, or can be used. Cleans according to Sa 2. 5 or Sa 3 standard. This grade can also be used for the rehabilitation of concrete, stone and masonry. 

Surface roughness: 20-30µm

For special coating removal on sensitive surfaces like plastic, for example for turbine cleaning. 

Surface roughness: 10-15µm

For removing coating for example on sensitive surfaces such as glass fiber or carbon fiber. 

Surface roughness: 10-15μm

For very fine cleaning for example of turbines, where a minimum removal of the surface coating is required. 

Surface roughness: 4-8μm

For special cleaning, for example to remove impurities from steel or stainless steel. 

Surface roughness: 10-15µm

For cleaning or finishing where a glossy surface is required. 

Surface roughness: 4 - 8µm

For the gentle removal of dirt, soot, smoke, liquids etc. from steel, concrete or stone surfaces. 

Surface roughness: 4-8µm

For the removal of coatings on sensitive surfaces or if metal roughening is not desired. 

Surface roughness: 0µm

100% Sponge - for light cleaning applications. No blasting media is added to the Sponge. 

Surface roughness: 0µm
