Polyamide Chemical Resistance by Technyl

Technyl® solutions for fluid parts in systems

Today’s fluid barrier applications require product materials that hold up under severe conditions. Exposure to harsh liquids, high pressure, and broad temperature ranges represents a tough, yet mission-critical challenge for both human safety and product performance.

Technyl® polyamide solutions from Domo Engineering Plastics offer the chemical, vapor, and temperature resistance properties that manufacturers need for automotive and industrial applications. Particularly well-adapted for parts and systems involving fuel handling, pneumatics/hydraulics, cooling, and other containment requirements, Technyl® offers a flexible and cost-effective alternative to standard and long-chain polyamides.



Main Technyl® fluid barrier benefits

  • Excellent chemical, temperature and UV resistance for a strong fluid barrier
  • Bio-sourced materials for injection and extrusion applications
  • High metal bonding capacity as a coating material

Keeping fluids where they belong

With extrusion and injection grades, Technyl® fluid barrier solutions cover your needs from pipes and tubes to salt-resistant automotive parts. Technyl® offers excellent metal bonding capacity, such as for coating aluminum to replace expensive copper tubing in cooling appliances and systems. 

Key features
