PPS sheets (polyphenylene sulfide sheets) are high-performance thermoplastic engineering plastic sheets with excellent comprehensive properties, making them ideal for many high-end applications. The oxidation resistance of PPS boards comes from the unique molecular structure of PPS resin, which provides exceptional oxidation stability.

PPS boards can withstand continuous high temperatures of 200-240°C in air, with short-term tolerance above 300°C without significant oxidative degradation. This stability comes from the aromatic ring structure and thioether bonds in its molecular chain, which resist oxygen damage. The material maintains structural integrity and performance consistency when exposed to sunlight, moisture, or corrosive gases, without discoloration, cracking, or strength reduction. It also resists oxidation from chemicals like dilute nitric acid and hydrogen peroxide solutions.

• Superior service life compared to ABS and PP in oxidative environments, reducing replacement costs
• Maintains mechanical properties and dimensional stability in high-temperature applications (industrial furnaces, engine compartments)
• Combines oxidation resistance with chemical corrosion and radiation resistance for harsh environments
• Simplifies design by eliminating need for additional oxidation protection measures

The exceptional oxidation resistance of PPS boards, combined with their mechanical properties and chemical stability, makes them ideal for replacing metals and ceramics in high-temperature industrial applications.
