Frequently Asked Questions (FAQ)
Why is LGF PP preferred over ordinary glass fiber reinforced PP in cars?
LGF PP offers twice the fatigue strength at high temperatures (120℃) and superior anti-warping properties, making it more reliable for structural automotive parts.
How does LGF compare to reinforced nylon regarding heat resistance?
LGF reinforced PP actually performs better, providing a fatigue strength that is approximately 10% higher than glass fiber reinforced nylon at elevated temperatures.
What are the main benefits of "Long" glass fibers compared to "Short" fibers?
Long glass fibers provide a three-dimensional network that enhances durability, reliability, and provides much better resistance to warping and deformation.
What specific car interior parts can be made with this material?
It is commonly used for dashboards, seat support plates, shift seat bases, and noise baffles to ensure strength and weight reduction.
Is LGF material suitable for exterior automotive components?
Yes, it is widely used for exterior and structural parts such as bumpers, front-end modules, and bottom protection plates due to its impact resistance.
Does LGF PP help in improving vehicle durability?
Absolutely. Its high fatigue strength and heat resistance ensure that structural parts maintain their integrity throughout the vehicle's lifespan.
