Air Induction Systems

Amodel® PPA Outperforms Conventional Nylons

With a heat deflection temperature of 280°C (536°F) and continuous-use temperature up to 210°C (410°F), Amodel® polyphthalamide (PPA) can take the heat in under-the-hood applications that are too demanding for conventional nylons and polyesters. This allows charge air cooler (CAC) housings, airflow valves, throttle bodies and other components molded from Amodel PPA to maintain their high strength and stiffness along with excellent creep and fatigue resistance when exposed to high heat and thermal cycling.

Key Features

  • Excellent mechanical properties over a broad range of operating temperatures and pressures
  • Continuous use up to 210°C (410°F)
  • Excellent resistance to automotive fluids, cleaners and road salts
  • Low moisture absorption
  • Excellent dimensional stability

Typical Applications

  • CAC Hot Air Ducts
  • CAC Housings
  • Diesel Airflow Valves
  • EGR Valves & Housings
  • Throttle Bodies
  • Turbocharger Housings

Wear-Resistant Plastics for Turbocharger Components

Turbocharger bushings, seal rings and other internal components are some of the most demanding applications in air induction systems. They must withstand extreme temperatures, wear, loads and aggressive chemicals in lubricated and non-lubricated environments over a wide range of critical pressures and velocities.
Wear-resistant grades of Torlon® PAI and KetaSpire® PEEK are formulated to give you just the right combination of mechanical and tribological properties to effectively replace metal in high-temperature friction and wear applications.
For comparable PEEK performance with up to 30% lower cost, consider our new wear-resistant AV-700 grades of AvaSpire® PAEK.
Key Features
  • Long-term use from 120-265°C (248-509°F)
  • Short-term use up to 280°C (536°F)
  • Lubricated and non-lubricated environments
  • Self-lubricating for longer life
  • Lighter weight and less noise than metals
  • Non-corrosive and non-galling
Typical Applications
  • Bearing Retainers
  • Bushings
  • Compressor Wheels
  • Isolation Disks
  • Seal Rings

Cooling and Heating Systems

Amodel PPA Delivers Full-Size Performance for 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.

Corrosion Protection

Diofan® PVDC Corrosion Protection for Automotive, Railway, Agricultural and Construction Machinery Parts

Thanks to its unrivalled low moisture and water permeability, single coats or primers based on Diofan® PVDC Dispersions exhibit outstanding corrosion resistance, even in the most severe environments. Diofan® based anticorrosive coating formulations enable cost efficient, reliable protection for automotive underbody and part coatings as well as for components in railway, agricultural, construction machinery and many other applications.

Diofan® binders provide excellent early water resistance, with overall performance equivalent to that obtained from traditional high performance solvent based paint systems (salt spray performance > 1000 h). Diofan® dispersions help in the formulation of highly technical, one-pack, water-based paints which are better for both health and the environment.

This low VOC dispersion (<100 ppm) allowing for the production of anticorrosion systems compliant with European and local regulations, notably those related to VOCs.

Fuel Systems

Improve Fuel Economy & Reduce Emissions

High-Temperature Components

Amodel® PPA is compatible with a wide variety of fuel blends and thrives in the much hotter, confined and stressed environments created by today’s engines.

Multi-Layer Extrusion

Ixef® PARA is enabling a new technology designed to help small engine fuel tank manufacturers more cost-effectively meet CARB and EPA standards.

Optimal Pipes, Tubes and Hoses

Algoflon® DF powders are used for pipes and tubings for fuel transport in automotive systems with exceptional performance:

Solef® PVDF qualities of impermeability and chemical resistance recommend their use in automotive fuel transport systems. A layer of Solef® PVDF within the construction of a multi-layer fuel line enhances the strength, permeation resistance and durability of the hose.

High Performance Seals

Tecnoflon® fluoroelastomers offer resistance to the most aggressive fuel mixtures while providing excellent properties for the lowest permeation. Tecnoflon® FKM grades have been designed to cover a broad operating temperature range: -40°C to +250°C. Applications include O-rings, fuel line quick-connect seals, fuel sender unit seals, fuel host connectors and fuel cap seals.
