The high concentration of mineral filler is evident along
the edge of this particle. Without reflected darkfield
illumination the color of the particle can't be determined.
Transmitted Off-Crossed Circular Polarized Light
Definition/Function:
Shoe wear particles as presented here refer to shoes with an elastomer sole. These may
be a variety of colors but tend to have a very high
mineral filler content, typically calcite. They may also have a high plasticizer
content. Some are acetone soluble.
Significance in the Environment:
shoe wear particles are common in high occupancy indoor spaces.
Characteristic Features:
Shoe wear particles have a much higher mineral filler content than tire or belt-drive
wear particles. The mineral filler particles also tend
to be much larger than that in tire or belt-drive wear particles.
