polyphenylene oxide (PPO) PPO history

1915 year USA Huntuer首先以无取代基 苯酚 mono is 主, made molecular weight relatively low PPO polymer. 1957 year USA GE company Hay using/adopting oxidation method made polymer/macromolecule amount 2,6位取代基 polymer,

1961 year Pricl use iron 氰化钾 as catalytic agent, use for 卤化苯酚进行 polymerization reaction, high shrinkage rate polymer/macromolecule amount material.

USA GE company 于1965 year utilizing Hay technology, using/adopting oxidation method combined formed method achieve industrial production. PPO although has many advantages, 但也存 in more defect, main/primary performance in melt temperature degree high, melt degree large, thermoplastic property molding property and other 方面, made its application. therefore, GE company using/adopting mixed polystyrene (PS) （PS） or high impact resistance polystyrene (PS) （HIPS） methods, formed for PPO add modified, improve/increase PPO resistant force cracking property, 并于1967 year achieve modified engineering plastics polyphenylene oxide (PPO) world PPO production technology is USA GE company 垄断,

1979 year Japan development polystyrene (PS) grafting property PPO resin, in 此期间MPPO（PPO and other plastics blending modified formed engineering plastics alloy ） development most fast,

20世纪90 year upper semi still maintain relatively fast development speed degree,

to 90 year 代末几乎无 growth, 2013 year market upper product 几乎都 is PPO alloy product, its in mixed resin 30%-70%, PPO content is 45%. MPPO以 its excellent comprehensive property can and more product grade as is general purpose engineering plastics obtain speed development, already formed is 当今继 engineering plastics polyamide (PA) （PA）, engineering plastics polycarbonate (PC) （PC）, engineering plastics polyoxymethylene (POM) （POM）, engineering plastics polybutylene terephthalate (PBT) （PBT） and engineering plastics polybutylene terephthalate (PBT) （PET）之 rear world large general purpose engineering plastics

polyphenylene oxide (PPO) PPO property can

1, is white pellets. comprehensive property can good, can in 120 degree in use, electrical insulation property good, water small, has force cracking toward. modified polyphenylene oxide (PPO) can remove force cracking.

2, has electrical insulation property and resistant water property excellent, has relatively good wear resistance and electrical property can, dimensional stability good. its electrical property can plastics 首位.

3, MPPO is PPO and HIPS blending made modified material, upper material is types material.

4, has relatively high heat resistant property, 玻璃化 temperature degree 211 degree, melting point 268 degree, add hot 至330 degree has separation understanding toward, PPO content high its heat resistant property good, heat deflection temperature (HDT) can 达190 degree.

5, flame retardant property good, tool has property, and HIPS mixed combined rear tool has in and other can property. light, can used for food and material industry. lightfast property 差, long time in cationic light lower use color.

6, can and ABS,HDPE,PPS,PA,HIPS, glass fiber and other blending modified 处理. PPO plastics raw materials features

A, PPO plastics raw materials 无毒, transparent, versus for density small, tool has excellent machine strong/high degree, resistant force 松弛, creep resistance, heat resistant property, resistant water property, resistant water property, dimensional stability.

B, in very wide temperature degree, frequency scope/range inner electrical property can good, hydrolysis, molding shrinkage small, flame resistant has self-extinguishing property, resistant machine acid, alkali, resistant 芳香烃, 卤代烃, type and other property can 差, easy solvent or force cracking.

C, it tool has rigid property large, heat resistant property high, flame resistant, strong/high degree relatively high electrical property can excellent and other advantages.

D, poly ether also tool has wear resistant, 无毒, resistant and other advantages

. E, PPO plastics raw materials dielectric constant and dielectric loss in engineering plastics in is most small product types 之一, 几乎不受 temperature degree, wet degree effect/influence, can used for low, in, high frequency electrical field/area.

F, PPO negative deformation temperature degree can 达190℃ above, temperature degree is -170℃.

G, main/primary disadvantages is melt flow property 差, processing molding difficult.

polyphenylene oxide (PPO) PPO application

实际 application large separation is MPPO（PPO blending material or alloy ）, use PS modified PPO, can large large improvement processing properties, resistant force cracking property and impact property can, reduce cost , is heat resistant property and gloss has reduce. modified polymer has PS（包括HIPS）, PA, PTFE, PBT, PPS and various elastomer, poly silicon oxygen 烷, PS modified PPO历 history long, product amount large, MPPO is use amount most large general purpose engineering plastics alloy product types. comparison large MPPO product types has PPO/PS, PPO/PA/ elastomer and PPO/PBT/ elastomer alloy.

polyphenylene sulfide (PPS) PPS brief introduction

polyphenylene sulfide (PPS) full is poly 苯基硫 ether, is separation 子主链 in belt/tape has 苯硫基 thermoplastic property resin, polyphenylene sulfide (PPS) is types crystallization property polymer. tensile fiber tool has relatively large 无定形区（ crystallization degree is 5%）, in 125℃时发生 crystallization hot, 玻璃化 temperature degree is 93℃; melting point 281℃. tensile fiber in tensile process in generate separation crystallization, （ increase 至30%）, in 130—230℃ temperature degree lower for tensile fiber hot 处理, can make crystallization degree increase to 60—80%. therefore, tensile rear fiber has obvious 玻璃化转变 or crystallization hot phenomenon, its melting point is 284℃. tensile hot rear crystallization degree improve/increase, fiber density versus increase large, tensile front 1.33g/cm3 to tensile rear 1.34g/cm3, hot rear can 达1.38g/cm3.

PPS is types comprehensive property can excellent specialty engineering plastics. PPS tool has excellent high temperature resistance, corrosion resistant, resistant 辐射, flame retardant, material mechanical properties and good dimensional stability and excellent electrical property can and other features, by used as structure property polymer/macromolecule material, through filling, modified rear used as specialty engineering plastics. meanwhile, also can made formed various function property film, coating and composite/compounding material, in electronics electrical appliances, aviation aerospace, automotive and other field/area obtain formed application.
