FAQ
What does "Heat Aging Resistance" mean for this PP GF40?
A: Heat aging resistance means our LFT-G® PP GF40 is specially formulated to maintain its mechanical properties, like strength and impact resistance, after prolonged exposure to high temperatures. It is tested for over 1000 hours at 150°C to ensure long-term durability.
How does this differ from a standard PP GF40?
A: While both offer high strength, this AR (Aging Resistance) grade contains a special additive package that protects the reinforced polymer from thermal oxidation. This makes it far superior for components that will operate continuously in hot environments, like an engine bay.
Is this material suitable for engine covers?
A: Yes, it is an excellent choice for this application. The high Heat Deflection Temperature and long-term heat stability of this long glass fiber composite make it ideal for engine covers, providing structural integrity, noise reduction, and resistance to under-hood temperatures.
