Transcription of Delrin Data Sheet 2/03 - San Diego Plastics Inc.
1 Delrin Delrin (Acetal Homopolymer) Delrin is a crys-talline plastic whichoffers an excellent balance of propertiesthat bridge the gapbetween metals andplastics. Delrin possesses high tensilestrength, creep resist-ance and also exhibits lowmoisture absorption. It is chemically resist-ant to hydrocarbons,solvents and neutralchemicals. These properties along withits fatigue endurancemake Delrin idealfor many industrialapplications. Good dimensional stability Low moisture absorptionDELRIN can operate in wet environments with little effect on performance or dimensions. Excellent machinability High fatigue endurance High strength and stiffness properties Superior impact and creep resistance Chemical resistance to fuels and solvents Natural grade is FDA, NSF and USDA compliant Good wear and abrasion propertiesWith its low coefficient of friction and hard and resilient surface, Delrin is the material of choice in many wear s overall combination of physical, tribological and environmental propertiesmake it ideal for many industrial wear and mechanical applications.
2 Parts exposedto a moist or wet environment, such as pump and valve components, are especiallyappropriate. Other common uses for Delrin include gears, bearings, bushings,rollers, fittings and electrical insulator PROPERTY VALUESD ensitySpecific GravityWater Absorption, @24 hours, 73 F@Saturation, 73 FD792D792D570D570lbs/in3g/cc%%Tensile Strength @ Yield, 73 FTensile ModulusElongation @ Break, 73 FFlexural Strength, 73 FFlexural Modulus, 73 FCompressive StrengthIzod Impact Strength, 73 FRockwell Hardness, 73 FShure HardnessWear Factor Against Steel, 40 psi, 50 fpmStatic Coefficient of FrictionDynamic Coefficient of Friction, 40 psi, 50 fpmD638D639D638D790D790D695D256D785-D370 2-D3702D37029,000350,0002511,500420,0005 ,2001. 5M 94 (120)-55 x (R) ScaleD Scalein3x1hr PVHeat Deflection Temperature @ 66 psi@264 psiCoefficient of Linear Thermal ExpansionMaximum Servicing Temperature, Intermittent Long TermSpecific HeatThermal ConductivityVicate Softening PointMelting PointFlammabilityD648D648D696-UL746B---D 2133UL94 F Fin/in/ F F FBTU/lb- F- F x ( )Surface ResistivityVolume ResistivityDielectric StrengthDielectric Constant, @ 60 Hz, 73 F, 50% RH@ 1 MHz@ 20 GHz@ 30 GHzDissipation Factor, @ 60 HZ, 73 FD257D257D149D150D150D150D150D150ohm/squ areohm- information is only to assist and advise you on current technical knowledge and is given without obligation or liability.
