Frequently Asked Questions
PES vs PPSU — when to choose which?
PPSU has higher impact resistance (690 vs 85 J/m) and better ESCR to disinfectants. PES has slightly higher Tg (225°C vs 220°C), better transparency (lighter amber tint), and is 20-30% lower cost. For medical devices requiring maximum toughness and chemical resistance, PPSU. For sterilization trays and plumbing where transparency and cost are priorities, PES.
