Rod PPS Meldin® 4000 PAI

aeronautical

Product overview
Meldin® 4000 is Omniseal Solutions' line of PAI (polyamide-imide) based compounds. Individual grades in the 4000 series differ by formulation to provide specific combinations of thermal stability, mechanical strength and wear performance. Meldin® 4000 materials are supplied primarily as injection-molding grades capable of meeting tight dimensional tolerances; limited prototype shapes are also available.

Key properties

• Mechanical strength retained at elevated temperatures
• High fatigue resistance under cyclical stress (preserved tensile and flexural properties)
• Excellent wear resistance and durability in abrasive or harsh environments
• Chemical compatibility with many fluids (e.g., fuels and oils)
• Self-lubricating behaviour and dimensional stability in aggressive chemical environments
