DuPont Zytel HTN 51G35HSL Other Engineering Plastics (Other) Supplier | High-Temperature Parts

Product Overview

DuPont Zytel HTN 51G35HSL is a 35% glass-fiber-reinforced PPA (polyphthalamide) grade engineered for extreme thermal and mechanical performance. It withstands continuous-use temperatures well beyond standard PA66, making it ideal for automotive and electronics components exposed to sustained heat.

The heat-stabilized formulation (HSL) provides long-term thermal aging resistance, while the high glass content delivers exceptional stiffness and creep resistance for load-bearing applications.

Key Advantages

Continuous-use temperature up to 185°C
Exceptional stiffness from 35% glass reinforcement
Excellent long-term heat-aging resistance
High creep and fatigue resistance
Outstanding dimensional stability

Applications

Engine cooling system parts
Turbocharger components
Power electronics housings
Transmission components
High-heat connectors
