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 possess good impact resistance, a characteristic that enables them to maintain structural stability when subjected to external impact or vibration.

In their molecular structure, rigid benzene rings and sulfur atoms are alternately connected, forming a strong molecular framework that endows the material with high mechanical strength and toughness. When subjected to impact loads, PPS sheets can absorb part of the energy through the deformation of molecular chains, reducing the risk of brittle fracture. Even in low-temperature environments, this impact resistance does not decrease significantly, and they can still maintain a good impact-resistant effect. After modification treatments such as glass fiber reinforcement, the impact strength of PPS sheets can be further improved, enabling them to adapt to more severe impact conditions.​

Based on their excellent impact resistance, PPS sheets have specific applications in multiple fields. In the automotive industry, they are often used to make protective components around engines, buffer gaskets for chassis, etc., which can withstand vibrations and slight collisions during vehicle operation, protecting key components from damage. In the field of electronic equipment, as casings or internal support structures, they can resist impacts generated when equipment is dropped or during transportation, ensuring the safety of electronic components. In mechanical manufacturing, they can be used to make protective baffles for machine tools and wear-resistant and impact-resistant parts of transmission systems, reducing losses caused by impacts during mechanical operation. In addition, in the field of rail transit, PPS sheets can be used for decorative panels and structural supports inside trains, coping with vibrations and impacts during train operation, and ensuring safety and durability in use.
