The PPS is a semi-crystalline engineering plastic with main chain structure consisting of benzene rings and sulfur atoms alternately. The molecular structure of PPS endows it with the following key characteristics: high temperature resistance, excellent chemical inertness, electrical insulation and wear resistance. The melting point of PPS is about 280℃, and it can keep stable performance in high temperature environment for a long time (usually in the range of 200~240℃), so it is one of the ideal materials for high temperature application.

Flexible materials play a vital role in space exploration, nuclear environments, and various types of radiation shielding and protection. Based on the absorption and attenuation effects of elements such as carbon, hydrogen, sulfur, gadolinium, tantalum, and tungsten on neutrons and high-energy radiation, linear polyarylsulfides containing elements such as gadolinium have been designed and produced at the molecular level. By adding no more than 20% gadolinium tungstate or gadolinium borate nanowhiskers, the product's shielding capability against neutron radiation is further enhanced. Gadolinium-containing polyarylsulfide fibers (0.1-1.0 mm) were prepared by using melt spinning technology and then woven into various radiation shielding fabrics. Additionally, gadolinium-containing polyarylsulfides can be processed into films ranging from 5 to 100 μm in thickness by a casting machine. The resulting fibers, fabrics, and films can be used at temperatures ranging from -50 to 250°C and cannot be corroded or dissolved by any solvent below 200°C. Meanwhile, these materials are resistant to a radiation dose of 10⁸–10¹⁰ Gy without cracking or deformation, and can efficiently shield against various high-energy radiation such as neutrons, γ rays, and X-rays.
High-purity polyphenylene sulfide ultrafine particles are shaped through heating and laser ablation for coating and packaging. However, the particle size and purity of common polyphenylene sulfide cannot meet the requirements. To control particle size distribution, XNH produces polyphenylene sulfide resins with linear molecular weight and ultrafine particle size (10-50 µm) by regulating the polymerization process. According to clients' demands, the melting point of ultra-fine polyphenylene sulfide particles ranges from 230 to 290°C. It can be used at temperatures between 200 and 260°C while keeping the high toughness of conventional polyphenylene sulfide.
