MODIFIED PPS

PPS plastic features outstanding heat resistance and inherent flame‑retardant property. It delivers superior chemical‑corrosion resistance, excellent dimensional stability and ultra‑low water absorption. Glass‑fiber‑reinforced PPS achieves greatly enhanced mechanical strength for metal‑replacement applications. The following covers other modification types for PPS.

Anti‑Aging Modification PPS possesses excellent intrinsic anti‑aging performance with stable molecular structure, and its radiation resistance is unmatched by other engineering plastics. With superior radiation‑resistance capability, PPS serves as the only ideal material for environments exposed to nuclear radiation such as atomic bomb and neutron‑bomb scenarios. For light‑aging resistance, weatherability of PPS can be further improved by adding antioxidants and UV absorbers. Anti‑aged PPS is widely adopted in aerospace components, nuclear‑industry equipment, long‑term high‑temperature parts around automotive engine compartments, as well as outdoor‑service electrical‑electronic housings and lighting‑system components.

Medical‑Grade Modification Intrinsically non‑toxic, PPS stands out for high‑temperature sterilization resistance and tolerance to chemical disinfectants. Medical‑grade modified PPS adopts raw‑material formulations complying with medical standards including FDA and ISO 10993, ensuring non‑cytotoxic, non‑sensitizing and non‑irritating properties. Its radiation‑resistance qualifies it for medical devices requiring gamma‑ray or electron‑beam sterilization. Medical‑grade PPS is widely used for repeatedly‑sterilized medical products such as surgical‑instrument handles, dental‑device components, medical trays, high‑temperature disinfection boxes, medical‑equipment housings and drug‑delivery‑system assemblies.

Food‑Grade Modification Food‑grade modified PPS applies formulations complying with food‑contact standards such as FDA and EU 10/2011 to prevent migration of hazardous substances upon food contact. Featuring extremely high chemical stability and ultra‑low water absorption (< 0.02 %), PPS enjoys natural advantages for food‑contact applications. Food‑grade PPS is widely used for high‑temperature food‑processing‑equipment parts, tableware (chopsticks, spoons, bowls and plates), heat‑resistant kitchen‑appliance components, food conveyor belts and beverage‑contact parts. Its high‑temperature performance makes it suitable for microwave‑safe tableware and dishwasher‑resistant components, while dimensional stability guarantees long‑term shape retention for precision food containers.
