LFT-G® PP GF40 (LGF40) – High Impact Copolymer
LFT-G® PP GF40 (Model: LFT-PP-GF40-NG04) is an advanced engineering composite featuring a rubber-toughened Copolymer Polypropylene matrix reinforced with 40% continuous long glass fiber.
While Homopolymer grades maximize stiffness, they often fail under sudden impacts. Our Copolymer base bridges this gap, delivering extraordinary ductility and shock absorption even in sub-zero environments. Manufactured via proprietary pultrusion, the continuous 10-12mm fibers create a virtually unbreakable 3D internal skeleton, preventing the shattering commonly associated with standard short glass fiber pp.
Core Material Advantages:
- ● Massive Shock Absorption: 45 kJ/m² notched impact resistance.
- ● Extreme Cold Toughness: Outstanding ductility even at -30°C.
- ● High Structural Rigidity: 8,600 MPa Flexural Modulus.
- ● Zero Moisture Absorption: Outperforms Nylon (PA6/PA66) in wet conditions.
Material Substitution ROI: Maximize Your Margins
For purchasing managers and design engineers, switching to LFT-G® Copolymer LGF40 is a highly strategic cost-saving decision. We deliver measurable Return on Investment (ROI) by eliminating systemic manufacturing inefficiencies.
- ● Vs. Die-Cast Metals: Achieve up to a 40% reduction in part weight. Completely eliminate secondary CNC machining, anti-corrosion coatings, and expensive metal tooling maintenance while retaining impact durability.
- ● Vs. PA6-GF40 (Nylon): Nylon requires costly pre-drying and absorbs moisture, causing dimensional warpage. Our Copolymer PP processes easily, requires zero moisture conditioning, and costs significantly less per kilogram.
- ● Vs. Short Fiber PP GF40: Eliminate warranty claims related to brittle fractures. The long glass fiber skeleton ensures parts survive drop tests, severe vibrations, and extreme operational abuse.

Industry Applications: Extreme Toughness
EV Battery Trays & Sub-Frames
Electric vehicle structural components are exposed to harsh road conditions and must survive massive underbody impacts. The impressive 45 kJ/m² impact strength of our 40% LGF Copolymer ensures the housing absorbs severe shock energy without fracturing, keeping sensitive battery cells protected.
Winter Sports & Action Gear
Standard plastics turn dangerously brittle in freezing weather. Engineered on a specially formulated Copolymer base, our LGF40 material retains its extreme ductility and shatter resistance even at -30°C, making it the perfect choice for ski bindings, snowmobile components, and safety gear.
Industrial Pump & Valve Housings
Fluid handling equipment suffers from both internal pressure surges (water hammer) and external abuse. The 40% long fiberglass skeleton prevents the casing from cracking open upon impact, providing a rugged, lightweight, and completely corrosion-free housing for industrial pumps.
Frequently Asked Questions (FAQ)
Q: What is the difference between Copolymer (Copo) and Homopolymer (Homo) PP GF40?
A: The main difference lies in toughness versus absolute stiffness. Copolymer PP is rubber-toughened, giving it vastly superior impact strength (up to 45 kJ/m²) and flexibility, especially in cold weather. Homopolymer PP is stiffer but much more brittle. If your part faces heavy shocks, drops, or crashes, Copolymer is the superior choice.
Q: Can Copolymer PP GF40 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 robust long glass fiber skeleton, it easily survives hard impacts at -30°C without breaking.
Q: Does switching from Aluminum to Copo LGF40 reduce costs?
A: Yes, drastically. LFT plastics can be injection-molded into highly complex geometries in a single step. This completely eliminates costly secondary CNC machining, manual trimming, and anti-rust painting processes, dramatically lowering the total manufacturing cost per part.
