What is YD PP GF40?
LFT-G® NG04YD PP GF40 is a 40% long glass fiber reinforced Polypropylene composite with high impact strength(>50KJ/m2)performance for pump body part copolymer material. This specialized glass reinforced plastic is engineered for applications demanding extreme toughness and structural reliability. By reinforcing a durable polypropylene copolymer with 40% long glass fiber and impact modifiers, this reinforced polymer delivers exceptional impact strength, far surpassing standard grades. Unlike short fiber versions that can be brittle, the interlocking long fiber network provides superior energy absorption, making it the premier choice for a robust water pump body plastic part, automotive components, and industrial housings that must withstand vibration and sudden impacts.

What is PP GF40 YD Grade used for?
Pump Body Part
This high-impact PP GF40 composite is specifically engineered to replace traditional materials like cast iron or bronze in demanding fluid handling applications. The material's exceptional toughness resists cracking from water hammer effects and mechanical stress, while its chemical resistance ensures a long service life, making it the perfect material for any modern Water Pump body Plastic.
A dialogue with our lead engineer on a recent client success:
"A client came to us with failing pump housings made from a short fiber composite; they couldn't handle the pressure spikes. We recommended our LFT-G® NG04YD PP GF40. The long fiber network dissipated the impact energy so effectively that they eliminated field failures entirely, all while reducing the part's weight by 30% compared to their previous metal design. It was a complete success."

FAQ
What makes this grade ideal for a water pump body?
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 is high impact strength achieved in this material?
A: The high impact strength in our LFT-G® PP GF40 YD grade comes from the combination of a toughened copolymer matrix and the energy-absorbing network of long glass fibers, which is far superior to the performance of short fiber reinforced plastics.
Is this PP GF40 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.
