Fans & Radiators LubricationHigh-Temperature Components

Fomblin® PFPE fluorinated fluids are high performance lubricants with exceptional properties such as:

• Low evaporation weight loss
• Low noise
• High viscosity index
• Anti-wear properties
• No carbonized residue formation
• Very long service life at high and low temperatures

Self-lubricating bearings can be used in places where re-lubrication is difficult. The use of Fomblin® PFPE enables system designs without reservoirs, reducing the weight and the size of the components.
Fomblin® PFPE are widely used as lubricants in sintered metal bearings for electric fans and radiators.

Amodel® PPA Delivers Full-Size Performance to Down-Sized Engines

Amodel® polyphthalamide (PPA) is a semi-aromatic polyamide that has successfully replaced die-cast aluminum in engine coolant systems for over 15 years. This high-performance polyamide offers fundamental performance advantages over conventional polyamides due to its aromatic nature and is routinely used to replace metal in under-the-hood applications where heat, humidity and chemical resistance are major considerations.

Similar to polyphenylene sulfide (PPS), Amodel PPA offers excellent dimensional stability in corrosive, high-temperature environments. In addition, it delivers better fatigue and impact resistance, better strength retention at 130°C (266°F) after prolonged exposure to engine coolants as well as faster cycle times when molding.
