LFT-G® CPP‑LGF40AS vs CPP GF40 (short fiber)
This chart compares our LFT-G® CPP-LGF40AS long glass fiber material with standard 40% short glass fiber reinforced polypropylene across five critical performance metrics for industrial components.
Key Industry Uses
Home Appliance & HVAC Structural Systems
Washer drum frames, AC compressor bases, refrigerator door hinge brackets, and boiler burner housings. CPP-LGF40AS delivers exceptional creep resistance and long-term dimensional stability, maintaining precise fitment even under continuous vibration and temperature fluctuations. Its excellent chemical resistance and low water absorption prevent deformation or performance degradation in humid environments, extending component lifespan by 3x compared to conventional short-glass alternatives.
Industrial Fluid & Power Transmission Components
Pump impellers, gearbox housings, hydraulic valve manifolds, and air compressor end caps. CPP-LGF40AS combines high strength with fatigue resistance to withstand high pressures and dynamic loads, while its low density reduces rotating inertia for improved system efficiency. Unlike metal components, it offers superior vibration damping and requires no corrosion protection, significantly cutting manufacturing and maintenance costs.
Competition & Electric Vehicle Chassis Systems
Bicycle frame components, RV structural brackets, kayak seat frames, and golf cart chassis parts. CPP-LGF40AS achieves an ideal balance of lightweight design and high specific strength, enhancing portability without sacrificing durability. Its outstanding impact resistance and weatherability stand up to harsh outdoor conditions, enabling complex one-piece designs that reduce assembly steps and deliver a smoother, more comfortable user experience.
FAQ
Q: What makes CPP LGF40 conductivity material different from standard short glass fiber reinforced PP compounds?
A: LFT-G® CPP‑LGF40AS uses 40% long glass fibers that form a continuous reinforcing network, delivering higher stiffness, impact strength, and creep resistance than short fiber compounds. Additionally, it is electrically conductive, which standard short glass fiber PP does not offer.
Q: Can CPP‑LGF40AS be processed on standard injection molding machines?
A: Yes, on conventional injection molding machines with a low‑shear screw and melt temperature between 200–230°C. Pre‑drying at 80°C for 2–3 hours is recommended to ensure consistent conductivity and mechanical properties.
Q: How does CPP‑LGF40AS achieve electrical conductivity?
A: A proprietary conductive additive system is incorporated during compounding, creating a uniform conductive network throughout the PP matrix. This enables reliable ESD protection without any post‑molding coating or painting.
