Benefits of ThermaX PSU
- Very high thermal properties superior to Ultem 9085
- Excellent hydrolytic resistance
- High Environmental Stress Crack Resistance (ESCR)
- Sterilization capable, including EtO gas, radiation, steam autoclaving, plasma, dry heat and cold sterilization
- Exceptional strength and modulus, even at elevated temperatures
- Outstanding impact resistance
- Highly resistant to even large (10 Mrd) doses of gamma radiation
- Resists most common automotive fluids including gasoline, antifreeze, transmission fluids, motor oils, power steering fluid, windshield washer fluid (ESCR, 24 hrs, 100C)
- Inherently flame retardant with low smoke evolution and low smoke toxicity
- Excellent dimensional stability with low creep sensitivity, low and uniform coefficient of thermal expansion, and highly reproducible part-to-part dimensions.
ThermaX PSU
Polysulfone (PSU) is a high-temperature aromatic sulfone polymer. PSU has excellent thermal and chemical resistance, making it well suited for demanding applications in automotive, aerospace, electronics, defense, food service, industrial, plumbing, medical, semi-con applications.
PSU is an excellent alternative to ULTEM 9085. While having a lower cost per kilogram and lower density (giving you more filament per kilogram as well), it maintains superior thermal properties. Its higher Tg and HDT give it higher strength and stiffness at elevated temperatures.
MADE IN THE USA
We manufacture all of our filaments in our 68,000 ft² manufacturing facility (located in Grand Rapids, Michigan) using state-of-the-art equipment and processes. Our goal continues to be to make the most innovative filaments on the market – targeting difficult end-use applications.
3DXTECH is now ISO 9001:2015 certified. This internationally recognized standard for quality management systems reflects a rigorous, third-party validation of how our organization establishes, maintains, and continuously improves its processes to ensure consistent quality
