Polyphenylene Oxide (PPO)ThermoplasticTrade Names• NorylManufacturerGE PlasticsGeneral DescriptionPPO is produced by the oxidative coupling of 2,6-dimethyl phenol.The resulting polymer is oxygen linked and properly called poly(2,6-dimethyl phenyl) 1,4-ether. PPO has excellent thermal stability,flame retardance, impact strength, and electrical properties. PPO alsohas one of the lowest moisture absorption rates found in anyengineering thermoplastic. Specialty grades available includegraphite/nickel, glass, glass fiber, carbon fiber, and stainless steelfilled. In 2004, the price of PPO ranged approximately from $2.00 to$3.76 per pound at truckload quantities.General PropertiesPPO is an engineering thermoplastic known for its excellent radiationresistance, oxidation resistance, thermal stability, and electricalproperties. In addition, PPO has outstanding dimensional stability,impact strength at low temperatures, and endurance. Because PPOhomopolymer is very difficult to process, PPO is often copolymerizedwith styrene, or a combination of butadiene and styrene, whichfacilitates processing and makes a wide range of physical propertiesavailable. PPO is chemically resistant to aqueous solutions, acids,bases and salt solutions, but only mildly compatible with oils andgreases. PPO is soluble in trichloroethylene, toluene, and ethylenedichloride, and may be stress cracked by other halogenated solvents,esters, and ketones. Due to PPO’s thermal stability and low moistureabsorption, products made of PPO can be repeatedly steam sterilizedwithout significant degradation and can also be metal-plated.Typical Properties of Polyphenylene Oxide (PPO)American EngineeringProcessing Temperature 450°F to 575°F 232°C to 302°CLinear Mold Shrinkage 0.004 to 0.009 in./in. 0.004 to 0.009 cm/cmMelting Point 415°F to 500°F 213°C to 260°CDensity 64.9 to 69.3 lb./ft. 3 1.04 to 1.11 g/cm 3Tensile Strength, Yield 4.6 to 10.1 lb./in. 2 x 10 3 3.2 to 7.1 kg/cm 2 x 10 2Tensile Strength, Break 4.1 to 9.7 lb./in. 2 x 10 3 2.9 to 6.8 kg/cm 2 x 10 2Elongation, Break 4.4 to 85.0% 4.4 to 85.0%Tensile Modulus 2.9 to 3.8 lb./in. 2 x 10 5 2.0 to 2.7 kg/cm 2 x 10 4Flexural Strength, Yield 7.0 to 15.5 lb./in. 2 x 10 3 4.9 to 10.9 kg/cm 2 x 10 2Flexural Modulus 2.6 to 3.6 lb./in. 2 x 10 5 1.8 to 2.5 kg/cm 2 x 10 4Compressive Strength 7.3 to 16.6 lb./in. 2 x 10 3 5.1 to 11.7 kg/cm 2 x 10 2Izod Notched, R.T. 1.5 to 8.3 ft.-lb./in. 8.1 to 44.8 kg cm/cmHardness R115 - R120 Rockwell R115 - R120 RockwellThermal Conductivity 0.9 to 1.5 BTU-in./hr.-ft. 2 -°F 0.13 to 0.22 W/m-°KLinear ThermalExpansionDeflection Temperature@ 264 psiDeflection Temperature@ 66 psiContinuousService Temperature2.9 to 4.4 in./in.-°F x 10 -5 5.2 to 7.9 cm/cm-°C x10 -5SI180°F to 450°F 82°C to 232°C200°F to 450°F 93°C to 232°C200°F to 250°F 93°C to 121°CDielectric Strength 400 to 600 V/10 -3 in. 1.6 to 2.4 V/mm x 10 4Dielectric Constant@ 1 MHzDissipation Factor@ 1 MHzWater Absorption,24 hr.2.0 to 2.8 2.0 to 2.80.002 to 0.004 0.002 to 0.0040.06 to 0.10% 0.06 to 0.10%Typical Applications• Telecommunications – Television cabinetry,cable splice boxes, wire board frames• Automotive – Grilles, spoilers, wheel covers, fuse blocks• Business – Personal computers, printers• Machines – Bases, video display terminals58The Loctite ® Design Guide for Bonding Plastics, Volume 4
