260	Maintains ≈90～95% strength	Upper limit for continuous operation
300	Decreases to ≈80% strength	Limited to short-term use
≥350	Significant performance decline	Not recommended for use in such environments

Chemical Resistance

Chemical	Resistance Level	Notes
Acids	Good	Excellent resistance to most acids (some strong oxidizing acids require verification)
Alkalis	Good	Tested with NaOH and KOH
Organic Solvents	Good	Stable against ketones, esters, and hydrocarbons (some solvents require verification)
Oils	Excellent	Resistant to swelling or degradation
Fuels	Excellent	Resistant to swelling or degradation

Application Areas

• Aerospace structural components and high-temperature resistant kits
• Medical devices and implantable/contact components
• Chemical process equipment and corrosion-resistant parts
• Molds, fixtures, wear-resistant components, and end-use functional parts replacing metal components
• High-temperature insulation and structural support components for electronics

Usage Guidelines

1. Nozzle: It is recommended to use high-temperature alloy or ceramic nozzles with a temperature resistance of ≥420°C.
2. Heat bed: 160～250°C; use a high-temperature-resistant build plate (PEEK, Garnet glass + high-temperature adhesive or special adhesive).
3. Print chamber: Recommended to be enclosed and heated, with a chamber temperature of ≥70°C.
4. Filament pre-treatment: Dry at 120°C for 2～4 hours to prevent moisture-induced bubbles and filament breaks.
5. Nozzle diameter: 0.4～1.0 mm (for fiber-reinforced formulations, ≥0.6 mm is recommended).
6. Layer height: 0.1～0.25 mm; print speed typically 10～40 mm/s (depending on machine type and formulation).
7. Post-processing: Annealing: 200°C/2h → slow cooling (to enhance crystallinity and strength); specific processes must be validated per part.

Maintenance

Under normal operating conditions, inspection items include:

• After use, store the filament in a vacuum bag with desiccant
• Storage environment humidity ≤15% RH
• If the filament surface has moisture or bubbles, re-dry it
