PPSF (Polifenilsulfone)



PPSF (Polifenilsulfone)

Il PPSF/PPSU è il materiale con la più alta resistenza chimica e al calore; è ideale per applicazioni in ambito aerospaziale, automotive e medicale. I componenti realizzati in PPSF non possiedono solamente qualità meccaniche elevate, ma hanno anche un'ottima precisione dimensionale, per riprodurre perfettamente le prestazioni del prodotto finito.
E’ possibile sterilizzare il PPSF tramite autoclave a vapore, ossido di etilene, plasma, sterilizzazione chimica e radiazioni.
