Physical Properties for Acetron GP

Acetron GP
Quadrant EPP’s general purpose acetal and is the only porosity-free acetal product available today. Investments
in process technology by Quadrant EPP now provide the performance and machinability of acetal without center core porosity. Our

in-line photometric procedure assures every plate and rod is porosity-free as measured by Quadrant EPP’s quick check dye

penetrant test. For details of test methods, contact Quadrant EPP. Acetron GP natural is FDA, USDA, Canada AG, and 3A-dairy

compliant.
