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 boards exhibit good processing adaptability in terms of shaping. Although they are high-performance engineering plastics with stable molecular structures, they can still be formed and processed through various processes such as injection molding, extrusion, and compression molding. They can accurately shape complex geometric shapes to meet the design requirements of different industrial components. Moreover, after forming, they have high dimensional stability and are not prone to obvious deformation due to subsequent processing or environmental changes.​

In terms of toughness, PPS boards have a certain impact resistance. Although their flexibility is slightly weaker compared to some elastomer materials, they are not prone to brittle fracture when subjected to a certain degree of external impact and can absorb part of the energy through their own deformation. This characteristic enables them to better cope with sudden external forces in scenarios such as mechanical transmission and structural support, reducing damage caused by impact.​

Based on the above-mentioned shaping and toughness properties, PPS boards have a wide range of applications. In the electronic and electrical field, they can be made into various complex insulating brackets, housings and other components through precision shaping. Their good toughness can ensure that the components are not easily damaged by slight collisions during installation and use. In the machinery manufacturing industry, by utilizing their characteristics of easy shaping and certain toughness, transmission gears, bearing gaskets and other parts are produced, which can not only meet the precise size requirements but also withstand the impact force during transmission. In the automotive industry, they can be processed into various special-shaped structural parts and protective parts, adapting to the complex spatial layout inside the car, and maintaining stable performance in the vibration and impact environment during vehicle driving.​
