Drying<\/strong>: 120 \u00b0C for 3\u20134 h, target moisture <0.02% to prevent streaks or bubbles.<\/span><\/p>\n

Molding temperature<\/strong>: 350\u2013400 \u00b0C; mold 150\u2013180 \u00b0C for good surface finish and properties.<\/span><\/p>\n

Equipment<\/strong>: Wear-resistant screws recommended to minimize resin degradation.<\/span><\/p>\n

Secondary operations<\/strong>: PPSU can be CNC-machined, drilled, or cut; retains properties after steam sterilization (up to 1000+ cycles).<\/span><\/p>\n

 <\/p>\n

5. FAQs<\/span><\/h2>\n

 <\/p>\n

Q1: How does PPSU compare with PSU and PEI?<\/strong><\/span>
PPSU delivers higher impact resistance and thermal stability, making it more suitable for applications requiring repeated sterilization.<\/span><\/p>\n

Q2: Is DURADEX PPSU safe for food and water contact?<\/strong><\/span>
Yes. The grades are widely used in hot water connectors, filter housings, and food service parts.<\/span><\/p>\n

Q3: Do transparent grades discolor with use?<\/strong><\/span>
They maintain clarity well under normal use. For long UV exposure, additional protection is advised.<\/span><\/p>\n

Q4: Can the material withstand autoclaving?<\/strong><\/span>
Yes. DURADEX PPSU resists more than 1,000 sterilization cycles without notable performance loss.<\/span><\/p>\n

Q5: How can I order or request samples?<\/strong><\/span>
Juyuan supplies the complete DURADEX series and provides free samples for qualification testing.<\/span><\/p>\n
