Mixing of glass powder filled polymer composite in furnace

You can put an abstract (a brief description of your method) here and the text you would copy into an article.

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.

Equipment or Bill of Materials

MG200 recycled soda-lime glass powder, by Vitro Minerals crushed polypropylene

Calibration & Tolerances

zero balance w/ empty container before each measurement
tolerance of MyWeigh iM01 balance is 1000+/- 0.01 grams
sample mass should fall within a tolerance of +/- 0.1g, preferrably within 0.01 or 0.02 for more precision

Operation & Procedure

prepare sample compositions, starting with 100% polypropylene and increasing glass content in increments of 10% by weight, measured on a MyWeigh iM01 balance
store measured glass for each composition in a correctly labeled plastic container with closed lid

if containers of proper size are in short supply, use multiple smaller containers and label correctly
