在20世纪80年代，吴羽株式会社成功地研发出了一种无交联结构的线性PPS；1987年本公司与株式会社吴羽开展业务合作，开始携手开拓这款新型的PPS市场。线性PPS彻底改变了迄今为止市场对交联型PPS的评价，线性PPS改善了脆性，为新型的PPS奠定了坚实的基础
PPS 6165A6日本宝理--线性PPS与交联型PPS
以DURAFIDE®为代表的线性PPS与交联型PPS相比，具有以下特点。
拉伸率和冲击强度大，优异的韧性。
离子型杂质少，可用于要求较高的电子领域及燃料电池部品。
优异的热稳定性，容易成型加工。
熔接缝强度高，螺纹、压入等二次加工性能优异。
白色度高，可染色。
DURAFIDE的用途不仅限于汽车的灯座、水泵、混合动力汽车与电动汽车的PCU（集成功率控制单元）等各种电子部件，还被应用于办公设备、影音设备等的功能部件，且在混合水龙头及热水器等厨卫浴零部件上的应用也充分利用了材料的特性。
其优异的强度和耐热性，作为金属的替代树脂材料将被寄予更多的期待，这就是DURAFIDE。
PPS 6165A6日本宝理--Linear PPS and crosslinked PPS
Compared with the crosslinked PPS, the linear PPS represented by durafide has the following characteristics.
High tensile and impact strength, excellent toughness.
It can be used in electronic field and fuel cell parts with high requirements.
Excellent thermal stability, easy processing.
The welding seam has high strength and excellent secondary processing performance such as thread and pressing.
High whiteness, dyeable.
Durafide is not only used in various electronic components such as lamp holder, water pump, PCU (integrated power control unit) of hybrid electric vehicle and electric vehicle, but also used in functional components of office equipment, audio-visual equipment, etc. it also makes full use of the characteristics of materials in the application of kitchen and bathroom components such as hybrid faucet and water heater.
Due to its excellent strength and heat resistance, durafide is expected to be a substitute for metal.
