Industrial White Hard High Temp Plastic Sheet Polyphenylene Sulfide Material

PPS sheets (polyphenylene sulfide sheets) are a type of high-performance thermoplastic engineering plastic sheets with excellent comprehensive properties, and they have important applications in many high-end fields.​ PPS sheets exhibit excellent functions in terms of resistance to high temperature, which makes them irreplaceable in many industries.​

PPS sheets (polyphenylene sulfide sheets) are renowned for their excellent high-temperature resistance and are one of the ideal materials for applications in high-temperature environments. Their long-term service temperature can be stably maintained at 200-240°C. Within this temperature range, the mechanical properties and chemical stability of PPS sheets can remain in good condition without obvious softening, deformation, or performance degradation. Even when exposed to higher temperatures for a short period, PPS sheets can exhibit strong tolerance, withstanding temperatures above 260°C. Even in a brief high-temperature environment of around 300°C, they can still maintain structural integrity and will not fail quickly.​

This excellent high-temperature resistance stems from their unique molecular structure. The molecular chain of PPS is formed by alternating benzene rings and sulfur atoms, forming a stable rigid structure with strong intermolecular forces, making the material less prone to molecular chain breakage or thermal decomposition at high temperatures. At the same time, it has good thermal stability and a high heat distortion temperature, which can resist thermal aging under continuous high-temperature effects and ensure the service performance of the material.​ It is precisely by virtue of such excellent high-temperature resistance that PPS sheets play an important role in many high-temperature operating scenarios, such as components in automobile engine compartments, components in high-temperature environments in the electronic and electrical fields, and related accessories of industrial kilns. They can adapt to harsh high-temperature working conditions and ensure the stable operation of equipment.
