塑料测试或鉴定法：
未增强的PPS密度为1.4gcmˉ³,帮会迅速沉于水，而慢慢沉于饱和的氯化镁溶液（密度为1.34）．制品主要以填充物料制成，因为密度较高；含40％GF的PPS密度为1.6gcmˉ³.纤维含量可达45％．一并使用矿物填料及玻璃纤维时，总填料量更可达65％（以重量计）
塑料及制品的处理：
吸水量少（0.05％，但矿物填料级的吸水量或会增加．尽管如此，加热有香于加工，故应烘干所有物料．用抽湿干燥机（温度可达175℃）以150℃烘3小时――普通焗炉甚至须要6小时．退火（通常以225℃烘2至4小时）可以达到佳的尺寸稳定性、遇热稳定性、坚固性、结晶程度及260℃以上的热变形温度（HDT）．
以一般情况而言，热模具（135℃以上）已可产生足够的结晶程度及上佳的表面．但如不要求制品定要耐热和稳定，便可采用冻模具（30-90℃）．此类（低结晶度）制品的HDT可能只有230℃．部件的表面或者较差，但比（高结晶度）制品更为刚韧耐用．可以150℃把矿物填料级烘干3小时．
