EMA 4161C PHYSICAL PROPERTIES OF POLYMERS COMPRESSION MOLDING/ MECHANICAL PROPERTIES LABORATORY PURPOSE: To learn how mechanical properties are affected by orientation induced during processing MATERIALS: A sheet of amorphous PET 2L PET soda bottle (2) Polished steel plates Brass shim stock EQUIPMENT: Carver hydraulic press (20 kg) w/ heated platens Thermocouple Heavy duty pliers Punch die for ASTM D-638 dogbone samples Instron 1122 Tensile tester or equivalent Caliper Personal computer Razor blade or scissors Thermal protective gloves (high temperature) Safety glasses PROCEDURE: 1. Place the brass mold on the lower polished plate which should be position in the center of the lower platen. Place the second plate on the top of the brass mold. Close the platens to within a few millimeters. This will help heat the plates uniformly. 2. Preheat the platens to 180 ° C. This will require at least 30 minutes. BE CAREFUL THE HEAT FROM THE PLATENS AT 150
