PPS

Polyphenylene Sulfide (PPS) is a top-tier, high-performance thermoplastic material, specially engineered for rigorous applications and possessing a stellar portfolio of thermal, mechanical, and chemical properties. PPS is an emblem of durability and resilience, boasting insolubility in any known solvent under 200°C. It is a go-to choice for high-demand sectors including automotive, chemical processing, oil & gas, and electronics. It's inherent flame resistance and self-extinguishing qualities further elevate PPS's standing as an optimal choice for electrical/electronics applications.

Key Attributes

1. Melting Temperature (Tm) of 285°C
2. Glass Transition Temperature (Tg) of 85°C
3. Superior chemical resistance - insoluble in any solvent under 200°C
4. Intrinsic flame resistance (UL94-V0)
5. Long-term hydrolytic stability - extremely low moisture absorption
6. Outstanding strength and modulus, maintaining performance even at high temperatures
7. Consistent dielectric constant and dissipation factor across various temperatures and frequencies

Printability of PPS

The stability of the chamber temperature is critical to prevent irregularities and maintain layer adhesion. Given the PPS temperature ranges from 315 to 345°C, an extruder capable of reaching these levels is mandatory. For successful printing, a specific adhesive, like Nano Polymer Adhesive, is required to be applied to the bed, and a three-layer application is recommended for optimal first-layer adherence. An actively heated and enclosed chamber with a temperature of at least 60°C is also necessary. After printing, PPS material shrinks as the chamber cools down and can potentially damage the bed due to its strength; it is important to remove the printout as quickly as possible. PPS filament is extremely susceptible to moisture and can readily absorb water, affecting the final print's strength. Therefore, it is essential to dry the material, preferably at 120°C before every use.

Extruder Temp: 315 - 345°C (requires all-metal extruder)
Bed Temp: 120 - 160°C
Chamber Temp: 60 - 90°C

Annealing of PPS

To optimize the crystallinity in the resin and bolster mechanical, thermal, and chemical resistance properties, it's crucial to anneal PPS parts post-printing. Typically, full annealing demands 2-4 hours of heating at 130°C.
