Quadrant® PPSU
Product Details
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 207 °C (405 °F).

Quadrant® LSG PPSU
Product Details
Quadrant LSG PPSU stock shapes are produced from selected batches of a specific Radel R polyphenylsulfone resin. This material offers a better impact strength and chemical resistance than Duratron® LSG PEI and LSG PSU and it also has superior hydrolysis resistance as measured by steam autoclaving cycles to failure. The composition of the resin used for the production of the Quadrant LSG PPSU stock shapes complies with the regulations that apply in the Member States of the European Union (Directive 2002/72/EC, as amended) and in the United States of America (FDA) for plastic materials and articles intended to come into contact with foodstuffs. Quadrant LSG PPSU stock shapes have also been successfully type tested for their compliance with both United States Pharmacopeia (USP) and ISO 10993-1 guideline requirements for Biocompatibility Testing of Materials, and they come with full traceability from resin to stock shape. These features, added to an excellent sterilizability by means of steam, dry heat, ethylene oxide, plasma and gamma irradiation, make Quadrant LSG PPSU stock shapes very suitable for applications in the medical, pharmaceutical and biotechnology markets.
