Description Delrin? FG500AL polyethylene is a medium viscosity acetal homopolymer, lubricating, low wear and / or the friction coefficient. It has been developed for consideration into applications such as parts for the food industry. Lubricant Additives performance characteristics of ultrasonic welding low coefficient of friction can be lubricated homopolymer good creep resistance good wear resistance medium viscosity gear conveyor uses non-specific food applications engineering parts RoHS Compliant contact the manufacturer Natural Color Pellets Processing Method Injection Molding Physical Nominal Value Unit Test Method Density 1.38 g/cm3 ISO 1183 melt flow rate (190 ° C/2.16 kg) 14 g/10 min ISO 1133 melt volume flow rate (MVR) (190 ° C / 2.16 kg) 12.0 cm3/10min ISO 1133 Shrinkage ISO 294-4 Across Flow: 2.00 mm 1.7% Flow: 2.00 mm 1.8% Mechanical Nominal Value Unit Test Method Tensile Modulus (23 ° C) 3000 MPa ISO 527 -2 tensile stress (yield, 23 ° C) 65.0 MPa ISO 527-2 Tensile strain (yield, 23 ° C) 11% ISO 527-2 off sheets rate (23 ° C) 23% ISO 527-2 Tensile creep modulus ISO 899-1 1 hr 2400 MPa 1000 hr 1600 MPa flexural modulus (23 ° C) 2800 MPa ISO 178 Impact Nominal Value Unit Test Method Charpy notched impact strength ISO 179/1eA -30 ° C 6.0 kJ/m2 23 ° C 7.0 kJ/m2 Charpy notched impact strength ISO 179/1eU -30 ° C 130 kJ/m2 23 ° C 160 kJ/m2 Thermal Nominal Value Unit Test Method Heat Deflection Temperature 0.45 MPa, Unannealed 164 ° C ISO 75-2 / B 1.8 MPa, Unannealed 97.0 ° C ISO 75-2 / A melting temperature of 4 178 ° C ISO 11357-3 ISO 11359-2 flow linear expansion coefficient: -40 to 23 ° C 0.00010 cm / cm / ° C flow: 23 到 55 ° C 0.00012 cm / cm / ° C flow: 55 到 100 ° C 0.00015 cm / cm / ° C Horizontal: -40 to 23 ° C 0.00010 cm / cm / ° C Lateral: 23 到 55 ° C 0.00012 cm / cm / ° C Lateral: 55 到 100 ° C 0.00017 cm / cm / ° C Injection Nominal Value Unit Drying Temperature 80.0 ° C Drying time - hot air dryer 2.0 to 4.0 hr recommended The maximum moisture content of <0.10% processing (melt) temperature of 210 到 220 ° C Melt Temperature, Optimum - Injection Molding 215 ° C mold temperature 80.0 到 100 ° C Mold Temperature, Optimum - Injection Molding 90 ° C Drying Recommended Not normally required unless moisture content of resin exceeds recommended level.
