LFT-G® PP GF40 Antistatic – Structural Safety & ESD Protection
LFT-G® PP GF40 Antistatic (Model: LFT-G®CPP-LGF40AS) is a specialized 40% long glass fiber reinforced Copolymer Polypropylene compound engineered for hazardous environments. Unlike standard engineering plastics, which are electrical insulators that accumulate dangerous static charges, this grade is modified with permanent antistatic agents to achieve a surface resistivity of 10⁸ to 10¹¹ ohms/sq.
Standard plastics naturally attract dust and can generate sparks up to 20,000 volts due to friction-a critical risk in mining, fuel handling, and electronics manufacturing. LFT-G® CPP-LGF40AS eliminates this risk by dissipating static electricity harmlessly.
Crucially, it retains the Long Glass Fiber (LGF) structural advantages. While many antistatic additives (like Carbon Black) can make plastics brittle, our proprietary formulation maintains high impact toughness (Copolymer base) and stiffness, making it the only viable choice for load-bearing components in explosive or dust-sensitive atmospheres.
Why Choose Long Fiber Antistatic PP?
-
● Explosion Prevention (ATEX Compliance): In environments with coal dust, grain flour, or fuel vapors, a static spark can be fatal. Our material prevents charge build-up, ensuring compliance with industrial safety standards.
-
● Dust Repellent Surface: High static charges attract dust and dirt, which degrades aesthetic appearance and mechanical function. LFT-G® Antistatic PP remains clean, reducing maintenance in textile and electronic assembly lines.
-
● No Compromise on Toughness: By using a Copolymer PP base and 10-12mm long fibers, we ensure the material remains ductile and impact-resistant, even while containing antistatic additives.
-
● Long-Term Stability: Unlike topical coatings that wear off, the antistatic property is integral to the polymer matrix, providing protection for the entire lifespan of the part.

Frequently Asked Questions (FAQ)
Q: What is the difference between Antistatic and Conductive PP?
A: It depends on the resistance range. Antistatic/Dissipative PP (like our LFT-G® grade) has a resistance of 10⁸-10¹¹ Ω, which drains charge slowly and safely to prevent sparks. Conductive PP has a resistance <10⁶ Ω, which conducts electricity instantly (like a wire) but can be dangerous if not properly grounded.
Q: Does the antistatic additive affect the mechanical strength?
A: Minimally. Unlike Carbon Black filled conductive plastics, which can be very brittle, our special antistatic formulation combined with 40% long glass fibers maintains excellent impact strength and stiffness. It is designed specifically for structural parts that need ESD protection.
Q: Is the antistatic effect permanent?
A: Yes. Standard antistatic sprays wear off. LFT-G® incorporates the antistatic agent directly into the polymer matrix during the pultrusion process. This ensures the antistatic performance lasts for the entire life cycle of the component, regardless of humidity or surface abrasion.
