LFT-G® PP GF30 (LGF30) – High Impact Copolymer
LFT-G® PP GF30 (Model: LFT-PP-GF30-CNG03) is a specialised Copolymer Polypropylene composite reinforced with 30% long glass fiber. Unlike Homopolymer grades that focus solely on stiffness, this Copolymer base is rubber-toughened to deliver extraordinary ductility and impact resistance, particularly in sub-zero environments.
Manufactured via pultrusion, the continuous 10-12mm fibers create an unbreakable 3D internal skeleton. This prevents the shattering and brittleness typically associated with standard short glass fiber pp, making it the ultimate lightweight replacement for metal in high-shock applications.
Core Material Advantages:
- ● Extreme Cold Toughness: Outstanding ductility even at -30°C.
- ● Massive Shock Absorption: 40 kJ/m² notched impact resistance.
- ● Zero Moisture Absorption: Outperforms Nylon (PA6) in wet conditions.
- ● Fatigue Resistance: Endures millions of high-stress vibration cycles.
Material Substitution ROI: Maximize Your Margins
For purchasing managers and engineers, switching to LFT-G® Copolymer LGF30 isn't just a technical upgrade; it is a strategic cost-saving decision. We deliver measurable Return on Investment (ROI) by eliminating systemic manufacturing inefficiencies.
- ● Vs. Die-Cast Aluminum: Achieve a 40% reduction in part weight. Completely eliminate secondary CNC machining, anti-corrosion coatings, and expensive metal tooling maintenance.
- ● Vs. PA6-GF30 (Nylon): Nylon requires costly pre-drying and absorbs moisture, altering dimensions. Our Copolymer PP processes easily, requires zero moisture conditioning, and costs significantly less per kilogram.
- ● Vs. Short Fiber PP GF30: Eliminate warranty claims related to brittle fractures and part failure. The long glass fiber skeleton ensures parts survive drop tests and severe operational abuse.

Industry Applications: Extreme Toughness

EV Battery Trays & Protectors
Electric vehicle battery trays are exposed to the elements and must survive massive underbody impacts from road debris. The 40 kJ/m² impact strength of our Copolymer LGF30 ensures the housing flexes and absorbs the shock energy without fracturing, protecting the sensitive battery cells inside.

Winter Sports & Outdoor Gear
Standard plastics turn dangerously brittle in freezing weather. Because it is built on a specially formulated Copolymer base, our LGF30 material retains its extreme ductility and shock resistance even at -30°C, making it the perfect choice for ski bindings and snowmobile chassis components.

Power Tool Housings
Industrial power tools suffer severe abuse, including frequent drops onto concrete floors. The long fiberglass skeleton prevents the casing from cracking open upon impact, providing a rugged, lightweight, and electrically insulating shield for the motor.
Frequently Asked Questions (FAQ)
Q: What is the difference between Copolymer (Copo) and Homopolymer (Homo) PP LGF30?
A: The main difference lies in toughness vs. stiffness. Copolymer PP is rubber-toughened, giving it vastly superior impact strength (up to 40-45 kJ/m²) and flexibility, especially in cold weather. Homopolymer PP is stiffer but more brittle. If your part faces heavy shocks or drop tests, Copolymer is the better choice.
Q: Can Copolymer PP GF30 withstand freezing temperatures?
A: Yes, exceptionally well. While standard plastics become glassy and shatter below 0°C, the ethylene segments within the Copolymer matrix maintain the material's ductility. Combined with the long glass fiber skeleton, it easily survives impacts at -30°C without breaking.
Q: Does switching from Metal to Copo LGF30 reduce costs?
A: Yes, significantly. While the raw material cost per kg might be comparable to some metals, LFT plastics can be injection-molded into complex geometries in a single step. This eliminates costly secondary CNC machining, trimming, and anti-rust painting, drastically lowering the total cost per part.
