PPSU

PPSU 3D Printing Filament
Polyphenylsulfone (PPSF or PPSU) is a high-temperature aromatic sulfone polymer.  Long considered to be one of the highest-performance polymers in the plastics world.  PPSF has excellent thermal and chemical resistance, making it well-suited for demanding applications in automotive, aerospace, electronics, defense, industrial, medical, and semi-con applications.

Attributes of Polyphenylsulfone PPSF (PPSU) include:
• Very high thermal properties with a Tg of 220°C and HDT of 205°C
• Excellent hydrolytic resistance
• High Environmental Stress Crack Resistance (ESCR)
• Outstanding impact resistance
• Highly resistant to gamma radiation – even in large doses (10 Mrd)
• Sterilization capable – including EtO gas, radiation, steam autoclaving, plasma, dry heat and cold sterilization.
• Resists most common automotive fluids, including gasoline, antifreeze, transmission fluid, motor oil, power steering fluid, windshield washer fluid (ESCR, 24hrs, 100°C)
• Inherently flame retardant with low smoke evolution and low smoke toxicity
• Excellent dimensional stability (low creep sensitivity and low, uniform coefficient of thermal expansion) and highly reproducible part-to-part dimensions
• Exceptional strength and modulus, even at elevated temperatures

Filament Specifications:
• Diameter:  1.75mm (+/- 0.05mm)
• Density:  1.29g/cm3

Recommended Print Conditions: (starting points)
• Extruder Temp: 370 – 390°C
• Bed Temp: 160-200°C
• Bed Prep: Rough Borosilicate Glass with PVP gluestick, or high temp carbon fiber sheet plus PVP glue stick, we also recommend the Vision Miner Nano Polymer
• Print Speed:  Print speeds of 20-30mm/s (starting point), faster as results dictate
• Enclosure Temp:  90-200°C (Bigger the part higher chamber temps are required)
• Drying Instructions: Please dry @110-120°C for 12-24 hours, for the first dry its recommended to dry for at least 24 hours before using, the drying time can be lowered using a vacuum oven and also storing the filament in a degassing chamber when not in use.
