A tough. rigid. high strength transparent thermoplastic. Polysulfone (PSU) maintains its properties over a wide temperature range (-150° F to above 300° F). often replacing polycarbonates when higher temperatures. improved chemical resistance or autoclavability is required.
Polysulfone (PSU) belong to a family of sulfur-containing thermoplastics, closely related to polyethersulfone (PES). Generally, this amber colored semi-transparent polysulfone is a high cost, rigid, material with low moisture absorption. Reinforcement improves toughness and further enhances dimensional stability, but turns materials opaque. In addition, polysulfones are characterized by high strength, very high surface-temperature limits, low creep, good electrical characteristics, transparency, self-extinguishing ability, and resistance to greases, many solvents, and chemicals, relative to polycarbonates.Polysufones may be processed by extrusion, injection molding, and blow molding. Polysulfone can be used as an alternative to polycarbonate or acrylic for applications requiring high temperature performance or exposure to hot water and steam.
Food-grade polysulfone and custom colors are available. Only food-grade polysulfone is FDA, NSF It is an amorphous high performance thermoplastic offering excellent mechanical, electrical, and improved chemical resistance relative to polycarbonate, 3A-Dairy and USP Class VI compliant.
