Ceramic Beads
Zirblast and Zirshot ceramic beads are manufactured
from mineral oxides using electro fusion. As a
consequence, the beads present a fine structure of
zirconia crystals uniformly enclosed in a silica
glassy phase. They combine high density and
high hardness. |
 |
Steel Grit/Stainless Steel Shot
 
Ervin AMASTEEL comes in three forms: shot,
grit and blend of the two. The sharp angular of the
grit form, makes it excellent for etching a texture
surface on metal - thus enhancing its ability to
bond paint, enamel, rubber, or other coatings. As
the leading international producer of cast steel
abrasives, Ervin Industries' AMASTEEL trademark has
become synonymous worldwide with product quality,
reliability and customer support.
|
 |
Glass Media
Rodeco glass beads are formulated of chemically
clean surface to protect parts and equipment.
The beads are spheres of uniform size and hardness
to impact the surface of the part. They
meet OSHA standards for cleaning operations, and
release no free silica or toxins that may harm
workers or the environment. |
 |
Garnet Abrasives
Barton garnet abrasives deliver high performance and
recyclability (up to 5 times) in a non-ferrous 100%
natural mineral. Garnet grains clean deep into
cavities and pitted areas down to bare metal
thoroughly removing all rust, soluble salts, and
other contaminants. Barton garnet abrasives are
ideal for use on steel, stainless steel, aluminum,
and other substrates and provide a surface that is
virtually free of embedment and rogue peaks and
troughs.
|
 |
Armex Soluble Blast Media
Delivered under pressure using compressed air (or
water) with soda blasting equipment, the non-toxic,
water soluble Armex baking soda crystal physically
removes coatings or soils from the substrate. Armex
removes paint and coatings, surface corrosion, dirt,
process residue, oils and grease, carbon, gasket
materials, etc... Armex is superb for steel,
stainless steel, aluminum, galvanized metal,
concrete, ceramic tile, glass, plastic, fiberglass,
rubber, and neoprene. |
 |
Plastic Media
If your operation involves any kind of surface
conditioning, treatment or coating removal, you
should consider the advantages of US POLYMEDIA.
It is fast, efficient and environmentally safe.
US POLYMEDIA is available in five different standard
aggression/ performance types: POLY Extra,
POLY Plus, POLY Hard, Poly V, AND POLY Blast.

 |
Aluminum Oxide

Due to its extreme toughness and low iron,
Rodeco's Brown Aluminum Oxide is used in the
manufacture of all types of bonded abrasives and for
general industrial applications.
White Aluminum Oxide boasts of a
extremely high purity that makes it suitable for
applications requiring minimum contamination of
foreign substances and sharp free cutting abrasive
characteristics.
|
 |
Silicon Carbide
Rodeco offers a full line of Silicon Carbide Grains
- both black and green - featuring extreme hardness
and uniformity of shape for superior performance and
outstanding efficiency in a variety of applications.
Applications include grinding, polishing, lapping,
special pressure blasting requirements and wire
sawing of materials such as super hard metals,
glass, ceramics and plastics.
