Firewire® PPS (Polyphenylene Sulfide) is a high-performance polymer that exhibits exceptional chemical resistance along with high thermal and mechanical properties. Widely known as one of the most chemically resistant thermoplastic materials available, PPS is insoluble in any known solvent under 200°C.
High-Temp Reels: We use reels made using PC/ABS and PC for our high-temp materials. This allows you to dry them out at higher temps once the filament absorbs moisture (which will happen to everyone eventually). The 250g and 500g reel are made using Polycarbonate (PC) and can be dried at 120°C if the filament gets wet. The 1kg reel is made using PC/ABS and can be safely dried at 115°C when it becomes necessary.
