LFT-G^® PA6 GF40 (LGF40) Black – Extreme Structural Nylon

Black LGF40 PA6 GF40 Long Glass Fiber Nylon LFT-G^® PA6 GF40 Black (Model: LFT-PA6-GF40-BG04) is an industrial-grade structural polyamide. It fuses a robust Nylon 6 matrix with a massive 40% long glass fiber continuous skeleton, presented in a sleek, UV-ready black formulation for heavy-duty exterior and under-hood applications.

Core Capabilities:

● Extreme Tensile Strength: Reaches 170 MPa, rivaling cast metals.
● Thermal Mastery: Maintains structural integrity up to 215°C (HDT).
● Moisture Mitigation: The dense 40% LGF network minimizes dimensional warpage typical in standard nylon.
● Aesthetic Finish: Deep black compounding ensures excellent surface quality without exposed glass fibers.

Industry Applications: High Heat & Heavy Load

Automotive Engine Cover LFT PA6 Black

Automotive Engine Components

Engine bay parts demand deep black aesthetics and extreme heat tolerance. With a 215°C HDT, our PA6 LGF40 perfectly replaces aluminum in engine covers, air intake manifolds, and oil pans, offering a 40% weight reduction while maintaining a flawless, UV-stable black finish.

Heavy Duty Power Tool Housing Black Nylon

Heavy-Duty Power Tools

Industrial drills and saws require housings that survive high-impact drops and intense motor heat. The 40% long fiber skeleton absorbs brutal shock waves that would shatter standard short-fiber plastics, ensuring the internal gears stay perfectly aligned.

Sporting Ski board part Nylon Gear

High-Stress Sporting Goods

From bicycle components to extreme sports gear, the sleek black PA6 LGF40 provides the ultimate stiffness-to-weight ratio. It delivers the premium cosmetic look consumers expect, coupled with the unbreakable tensile strength (170 MPa) that athletes demand.

Frequently Asked Questions (FAQ)

Q: How does the 40% LGF network mitigate Nylon's moisture absorption?

A: Polyamide 6 naturally absorbs moisture, which can lead to dimensional swelling and a loss of stiffness in unreinforced plastics. By integrating a dense 40% long glass fiber skeleton, we physically lock the polymer chains in place. This restricts the resin's ability to swell, drastically reducing dimensional warpage and maintaining high modulus even in humid conditions.

Q: Is the black color custom compounded or just a surface dye?

A: The model LFT-PA6-GF40-BG04 is fully compounded. The deep black pigment is integrated into the nylon matrix during the pultrusion process. This ensures consistent color throughout the entire wall thickness of your part, eliminating the need for secondary painting and providing excellent base resistance to UV degradation.

Q: Can PA6 GF40 truly replace die-cast Aluminum?

A: Yes, it is the primary use case. With a tensile strength hitting 170 MPa, it matches the functional strength needed for many brackets and housings. While aluminum is heavier and requires costly CNC machining and anti-rust treatments, LFT-G^® PA6 GF40 can be injection-molded into highly complex, lightweight, ready-to-use parts in a single step.
