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. The oxidation resistance of PPS boards stems from the unique molecular structure of PPS resin, endowing it with excellent oxidation stability.
Specifically, in air, PPS boards can withstand high temperatures of 200-240°C for a long time and even tolerate temperatures above 300°C for a short period without obvious oxidative degradation, thanks to the stable aromatic ring structure in its molecular chain and the chemical inertness of thioether bonds, which are not easily damaged by oxygen. Meanwhile, when exposed to sunlight, moisture, or corrosive gas environments, PPS boards are not prone to problems such as discoloration, cracking, or strength reduction due to oxidation, and can maintain long-term structural stability and performance consistency. In addition, it has a certain tolerance to various oxidizing chemicals (such as dilute nitric acid, hydrogen peroxide solution, etc.), is not easily oxidized and corroded, and is suitable for use in environments with chemical corrosion risks.
The core advantages of PPS boards based on their oxidation resistance are reflected in several aspects: Due to their outstanding oxidation resistance, they have a much longer service life than ordinary plastics such as ABS and PP in environments prone to oxidative aging like high temperature, humidity or outdoors, reducing the replacement cost caused by material failure due to oxidation; in high-temperature working conditions such as around industrial furnaces and automobile engine compartments, they will not soften, deform or have a sudden drop in strength due to oxidation, and can still maintain good mechanical properties such as impact resistance and wear resistance as well as dimensional stability; at the same time, combined with oxidation resistance, chemical corrosion resistance, radiation resistance and other properties, they can be used compatibly in various harsh environments without the need to design separate protective measures for "oxidation risk", simplifying the design difficulty of application scenarios.
In summary, the oxidation resistance of PPS boards is their core competitiveness in applications under high-temperature and complex environments. Combined with their excellent mechanical properties and chemical stability, they have become an ideal choice for replacing traditional materials such as metals and ceramics in high-end industrial fields.
