LFT-G® PA66 GF30
The choice for higher performance applications.
LFT-G® PA6 GF30
A versatile, cost-effective workhorse.
1. Thermal Performance (HDT @ 1.8 MPa)
Winner: PA66. Its significantly higher heat deflection temperature ensures superior structural integrity in under-the-hood and other high-heat environments.
2. Dimensional Stability (Lower Moisture Absorption)
Winner: PA66. Its lower moisture uptake means less dimensional change and more consistent mechanical properties in humid or wet conditions.

Frequently Asked Questions
Q: When should I choose LFT PA66 over LFT PA6?
A: Choose PA66 when your application involves continuous operation at temperatures above 120°C, or when it requires the utmost dimensional stability and property retention in humid or wet environments. While PA6 is a fantastic performer, PA66 is the superior choice for the most demanding thermal and environmental challenges.
Q: Does PA66 require different processing than PA6?
A: Processing is very similar, but PA66 requires higher melt and mold temperatures due to its higher melting point. A typical melt temperature for LFT PA66 is 280-300°C. As with all polyamides, mandatory pre-drying is absolutely critical to prevent degradation and ensure performance.
