Quadrant PPSU

Extruded Grade • Natural Color




Quadrant PPSU polyphenylsulfone (PPSU) is an amorphous high performance thermoplastic offering better impact resistance and chemical resistance than polysulfone and polyetherimide (Duratron PEI). Quadrant PPSU offers superior hydrolysis resistance when compared to other amorphous thermoplastics as measured by steam autoclaving cycles to failure. In fact, Quadrant PPSU has virtually unlimited steam sterilizability. This factor makes it an excellent choice for medical devices as steam autoclaves are widely used to sterilize medical devices. It also resists common acids and bases − including commercial washing solutions − over a broad temperature range.

Quadrant PPSU is stocked in natural (bone white) and available in transparent and custom colors. It is commonly used in sterilization trays, dental and surgical instrument handles, and in fluid handling coupling and fitting applications. Quadrant PPSU is USP Class VI compliant. It is suitable for use in electronic assembly equipment and devices that must withstand solder temperatures. Quadrant PPSU has a heat deflection temperature of 405F.

  • Impact resistance
  • High resistance to steam autoclaving
  • High modulus of elasticity and heat resistance
  • FDA Compliant
