Grade: Udel® P 1700
Formula: PSu
Form: Granule
Material: Polysulfone (PSU)
CAS Number: 25135-51-7
Commodity: Polymers
Nominal Granule Size:
2mm
Color:
Natural
Udel® P 1700 PSU (Polysulfone) granules are high-performance thermoplastics designed for medical, aerospace, and laboratory applications requiring superior thermal and chemical resistance. With a high glass transition temperature and hydrolysis resistance, these granules are ideal for precision-molded components exposed to high temperatures and repeated sterilization, such as surgical tools, biopharmaceutical filtration membranes, and analytical lab instruments. Their flame resistance and excellent dielectric properties make them indispensable in aerospace electronics, automotive electrical systems, and high-voltage insulation components. Additionally, their chemical stability enables the production of durable, contamination-resistant equipment for research laboratories and industrial processing environments.
