（1）一般性能：PPS为一种外观白色、高结晶度、硬而脆的聚合物，纯PPS的相对密度为1.3，但改性后会增大。PPS有吸水率极小，一般只有0.03%左右。
（2）机械性能：纯PPS的机械性能不高，尤其冲击强度比较低。以玻璃纤维增强后会大幅度提高冲击强度，由27J/m增大到76J/m，增大3倍；拉伸强度由6Mpa增大到137Mpa，增大1倍。PPS的刚性很高，在工程塑料中少见。纯PPS的弯曲模量可达3.8Gpa，无机填充改性后可达到12.6Gpa,增大5倍之多。
(3) thermal performance: PPS has excellent thermal performance,short-term can withstand 260 °C, and can be used in 200 ~ 240 °Cfor a long time; its heat resistance is e to Pi, secondonly to F4 plastic, which is also rare in thermosetting polymer.(4) Electrical Properties: PPS has outstanding electricalproperties, compared with other engineering plastics, itsdielectric constant and dielectric loss angle tangent value arerelatively low, and in a large range of frequency, temperature andtemperature changes little; PPS has good arc resistance; It's asgood as thermosetting polymer. PPS is often used in electricalinsulation materials, its dosage can account for about 30% . (5)chemical resistance: one of the major characteristics of PPS is itsgood chemical corrosion resistance, and its chemical stability issecond only to that of F4. PPS is stable to most acids, esters,ketones, aldehydes, phenols, aliphatic hydrocarbons, aromatichydrocarbons, chlorinated hydrocarbons, etc. , not Resistant tochlorinated biphenyls and oxidizing acids, oxidants, concentratedsulfuric acid, concentrated nitric acid, aqua regia, hydrogenperoxide and sodium hypochlorite, etc. . PPS has good radiationresistance. (6) PPS has good flame retardancy, and its oxygen indexis higher than 44% . Compared with other plastics, PPS is a highflame retardancy material (47% for pure PVC, 30% for PSF, 29% forPA66,28% for MPPO and 25% for PC) . PPS FORTRON 1131L4 ITT offersCOA, COC, rohs. . Msds. .
