# Siraya Tech PPA 1,75mm 1 kg

Il filamento **Siraya Tech PPA** (Polyphthalamide) è il materiale ideale per chi cerca massima resistenza, precisione e stabilità dimensionale anche nelle condizioni più estreme. Questo nylon ad alta temperatura è stato studiato per applicazioni ingegneristiche che richiedono resistenza chimica e termica, bassa deformazione ed eccellenza nelle prestazioni meccaniche.

**PPA** offre resistenza alla trazione eccezionale (72MPa), elevata rigidità, ottima resistenza flessionale (115MPa) e una superficie estremamente resistente all'abrasione grazie al basso coefficiente di attrito e capacità auto-lubrificante. La bassa assorbenza di umidità lo rende molto più stabile di tutti i tradizionali PA6 e PA66: è ideale per parti in movimento, ingranaggi, cuscinetti, fissaggi industriali, piastre, alloggiamenti elettronici e componenti auto e aerospace.

È compatibile con la maggior parte delle stampanti FDM professionali dotate di estrusore all-metal e garantisce ottimi risultati anche per oggetti dai dettagli complessi o dalle geometrie difficili, grazie alla ridotta propensione a warping e shrinking rispetto ai classici nylon.
