What is GF50 PP For Pump Grade?
LFT-G® NG05 YD PP GF50 is a 50% long glass fiber reinforced Polypropylene composite with high impact strength (Max>54KJ/m2) for pump part grade. This premium glass reinforced plastic is engineered for the most demanding applications where extreme toughness is required. This reinforced polymer combines a durable polypropylene copolymer with a high 50% loading of long glass fiber and specialized impact modifiers. Unlike short fiber versions that become brittle at high filler content, our long fiber technology creates a robust internal skeleton that provides superior energy absorption, making it the ultimate choice for a high-performance water pump body plastic part and industrial components that must withstand extreme vibration and pressure surges.

What is PP GF50 High Impact Grade used for?
Pump Body Part
This high-impact PP GF50 composite is engineered specifically to replace die-cast metals in demanding fluid handling systems, such as industrial and residential pumps. The material's exceptional toughness resists cracking from pressure spikes (water hammer) and mechanical stress, while its excellent chemical resistance ensures a long, reliable service life for any modern water pump body plastic part.
Expert Insight: A Case Study in Metal Replacement
"A client developing a high-pressure agricultural pump was experiencing field failures with a standard glass-filled plastic. We introduced them to LFT-G® NG05YD PP GF50. The long fiber network's ability to absorb and dissipate energy was the key. Not only did they eliminate cracking failures, but they also achieved a 40% weight reduction compared to the original aluminum design, leading to significant cost savings in both material and shipping."

FAQ
Why is this grade specified for pump parts?
A: This grade is perfect for a water pump body plastic part due to its exceptional impact strength to resist pressure spikes, excellent creep resistance to maintain dimensional stability under constant pressure, and the inherent chemical resistance of polypropylene.
How does it achieve such high impact strength?
A: The high impact strength in our LFT-G® PP GF50 YD grade comes from the synergy between a toughened copolymer matrix and the energy-absorbing network of long glass fibers, which is far superior to short fiber reinforced plastics.
Is this PP GF50 grade recyclable?
A: Yes, as a thermoplastic, this long glass fiber composite is fully recyclable. Promoting a circular economy is important, and our reinforced polymer can be reprocessed to create new, durable products at the end of its service life.
