What is PP GF30?
LFT-G® PP GF30 is a 30% long glass fiber reinforced Polypropylene composite. This advanced thermoplastic material leverages a matrix of polypropylene infused with 30% long glass fibers. During the injection molding process, these fibers form a robust, three-dimensional skeletal network within the part. This internal structure is the key to the material's remarkable performance, providing superior stress transfer and load distribution compared to standard short-fiber-reinforced plastics. The result is a high-performance "long glass fiber polypropylene" composite that offers an exceptional balance of stiffness, impact strength, and reduced component weight, making it a prime candidate for replacing metal in demanding structural applications.

What is PP GF30 used for?
Automotive Components
Industrial & Appliance Pump Components
The versatility of LFT-G® PP GF30 extends far beyond automotive. In the industrial sector, its robustness and chemical resistance are ideal for pump housings, impellers, valve bodies, and conveyor system components. It is also formed into structural frames for machinery, cooling fan blades, and durable power tool housings. In home appliances, it brings structural integrity and longevity to parts such as washing machine drums and paddles, dishwasher spray arms, and chassis for vacuum cleaners and air conditioning units. For sporting goods and recreational equipment, its high impact strength makes it perfect for kayak paddles, watercraft hulls, and various load-bearing brackets.
FAQ
Q: Is PP GF30 suitable for extrusion molding?
A: LFT-G® PP GF30 is primarily formulated for injection molding to create complex, high-strength parts. However, we do offer specific grades of long glass fiber polypropylene suitable for extrusion processes, typically used for profiles or sheets requiring high stiffness. For optimal results with injection molding, it's vital to use processing techniques that preserve fiber length, such as using low-shear screws and designing molds with smooth, generously sized runners and gates.
Q: What is the density of PP GF30 in kg/m³?
A: Based on our datasheet, the density of LFT-G® PP GF30 ranges from 1.12 to 1.15 g/cm³. To convert this to kg/m³, you multiply by 1000, resulting in a density of 1120 to 1150 kg/m³. This relatively low density, when combined with its high mechanical strength, gives PP GF30 an outstanding strength-to-weight ratio, which is a key advantage for lightweighting projects.
Q: What is the price of PP GF30?
A: The price of LFT-G® PP GF30 can vary depending on the specific grade, order quantity, and any custom additives or colorants required. For a precise quotation tailored to your project needs, please contact our sales team directly. It's also worth noting that due to the abrasive nature of glass fibers, using hardened tool steel for high-volume production molds is recommended to ensure tool longevity and consistent part quality.
