Introduction
polymer and glass have very different particle sizes (glass powder <44 micron, polymer ~5mm diameter) these particles will not mix evenly unless the polymer melts
Safety
- small particle size of glass powder poses a health hazard-- operate in fume hood if possible, wear safety glasses and respirator.

Calibration & Tolerances
Operation & Procedure
- prepare sample compositions, starting with 100% polypropylene and increasing glass content in increments of 10% by weight, measured on a balance with tolerance of +/- 0.1g
- store measured glass for each composition in a plastic container with closed lid
- email Dr. Paul Fraley (pdfraley@mtu.edu)
- take this safety training:
