FAQ
Q: Can LFT-G® HDPE GF50 replace metal in structural applications?
A: Yes. With 50% long glass fiber reinforcement, HDPE LGF50 delivers exceptional stiffness and impact strength comparable to metal, but at a fraction of the weight and with built-in corrosion resistance.
Q: What are the injection molding guidelines for LFT-G® HDPE GF50?
A: Recommended melt temperature ranges from 230–260°C, with mold temperature around 40–65°C. Due to the 50% fiber content, tool design should account for slightly lower shrinkage (approx. 0.3%) and ensure good venting.
Q: How does LFT-G® HDPE GF50 perform in chemical environments?
A: The HDPE base provides excellent resistance to acids, solvents, and industrial chemicals, while the glass fibers add structural integrity-making it ideal for chemical storage tanks and fluid handling components.
