PPS sheets (polyphenylene sulfide sheets) are high-performance thermoplastic engineering plastic sheets with excellent comprehensive properties, making them essential for many high-end applications. These sheets offer exceptional high-temperature resistance, making them indispensable in numerous industries.
PPS sheets are renowned for their outstanding high-temperature resistance, making them ideal for high-temperature environments. Their long-term service temperature remains stable at 200-240°C, maintaining mechanical properties and chemical stability without softening, deformation, or performance degradation.
Even in brief exposure to higher temperatures (above 260°C or around 300°C), PPS sheets maintain structural integrity and performance. This exceptional thermal stability comes from their unique molecular structure with alternating benzene rings and sulfur atoms, creating a rigid structure resistant to thermal decomposition.
PPS sheets are widely used in demanding high-temperature environments including:
Their ability to withstand harsh conditions ensures stable equipment operation in extreme environments.
