LFT-G^® PP GF30 FR – Structural Flame Retardant Copolymer

LFT-G^® PP GF30 FR (Model: LFT-G^®CPP-NG03FR) is a high-performance, safety-critical composite material. It features a 30% long glass fiber (LGF) reinforcement embedded within a tough Copolymer Polypropylene matrix, rigorously formulated to achieve the highest UL94 V0 flame retardant classification.

In traditional plastics engineering, incorporating flame retardant (FR) additives inherently severely degrades the mechanical properties of the base resin. Standard short-fiber PP GF30 FR materials often become unacceptably brittle, exhibiting poor impact resistance and low tensile strength, which limits their use in load-bearing structural parts.

LFT-G^® overcomes this fundamental industry challenge through advanced pultrusion technology. By utilizing 10-12mm continuous long glass fibers, we create an internal 3D skeletal network within the molded component. This long fiber skeleton fully compensates for the mechanical loss caused by FR agents, delivering a material that offers uncompromised structural integrity alongside absolute fire safety. It is the ultimate metal replacement for high-voltage environments and EV applications.

Why Choose Long Fiber PP GF30 FR?

● Certified V0 Flame Retardancy: Engineered to self-extinguish within 10 seconds during vertical burn tests without producing flaming drips. This ensures strict compliance with global electrical and automotive fire safety standards.
● Copolymer Impact Toughness: While homopolymer bases are stiff but brittle, our Copolymer PP matrix provides excellent ductility and low-temperature impact resistance, preventing parts from shattering under sudden shock or freezing conditions.
● Superior Creep Resistance: The 30% long fiber network locks the polymer chains in place. This prevents the material from deforming continuously under heavy static loads, which is crucial for structural brackets and battery housings.
● High GWIT & CTI Performance: Exhibits a high Glow Wire Ignition Temperature and excellent Comparative Tracking Index (CTi), preventing electrical arcing and ignition in high-voltage switchgears and connectors.

Frequently Asked Questions (FAQ)

Q: Is standard PP GF30 flame retardant?

A: No, standard PP GF30 is highly flammable. Polypropylene naturally burns easily and creates flaming drips. To achieve fire safety, specific flame retardant additives must be compounded into the resin. Our LFT-G^® NG03FR grade is specially formulated to achieve the highest UL94 V-0 rating, meaning it self-extinguishes instantly.

Q: Does adding flame retardant weaken PP GF30?

A: Yes, in short-fiber materials, but LFT solves this. High loadings of FR powders disrupt the polymer matrix, making standard short-fiber PP very brittle. By utilizing 30% Long Glass Fibers, we create a continuous 3D skeleton inside the part that fully compensates for this weakness, resulting in a V0 material that remains incredibly strong and impact-resistant.

Q: What is the continuous use temperature of FR PP GF30?

A: LFT-G^® Copolymer PP GF30 FR offers a high Heat Deflection Temperature (HDT) of around 145°C - 150°C. For continuous long-term use without mechanical degradation, it performs exceptionally well in environments ranging from -30°C up to 110°C, making it ideal for automotive under-hood or electrical applications.
