Processing Guidelines

To ensure optimal performance and minimize fiber breakage during the injection molding of LFT-G^® PP- GF30, follow these recommended processing steps and parameters:

Parameter	Recommended Range	Key Notes for PP LGF30
Drying Temperature ①	90 – 110 °C	Use a desiccant/dry air dryer to avoid hydrolysis
Drying Time ①	3 – 4 hours	Ensure uniform moisture removal before processing
Melt Temperature (Nozzle) ③	210 – 240 °C	Avoid overheating to preserve fiber integrity
Mold Temperature ②	40 – 60 °C	Balances flowability and part dimensional stability
Injection Speed	Slow to Moderate	Minimize fiber breakage and internal shear

Critical Tips：

Screw: Low-compression screw to reduce fiber breakage

Gating: Generous gating for smooth material flow

FAQ 

Q: How does LFT‑G^® PP LGF30 work?

A: LFT-G^® PP LGF30 enables significant weight reduction in metal replacement applications while delivering exceptional mechanical performance. Long glass fibers minimize anisotropic shrinkage, reducing warpage, and improve weld line strength compared to short‑fiber compounds.

Q: Is LFT‑G^® PP GF30 suitable for outdoor applications?

A: Yes, it offers excellent weatherability, chemical resistance, and UV stability with appropriate additives, making it suitable for demanding outdoor environments.

Q: What is the difference between PP and LFT‑G^® PP GF30?

A: Unfilled PP is flexible with low strength. LFT‑G^® PP GF30 (long glass fiber) offers higher stiffness. LFT‑G^® PP LGF30 uses long fibers for superior impact resistance and dimensional stability in structural parts.
