TPU LCF30 – 30% Long Carbon Fiber TPU

Long Carbon Fiber Reinforced Thermoplastic Polyurethane • 30% carbon fiber content • Engineered for high-performance structural applications

Description

LFT-G^®TPU LCF30 is a 30% long carbon fiber reinforced thermoplastic polyurethane (TPU) compound designed for demanding engineering applications. The continuous-fiber architecture delivers outstanding mechanical strength, thermal stability, and electrical conductivity - outperforming standard short-fiber compounds in load-bearing and ESD-sensitive environments.

Ideal for metal-replacement initiatives, TPU LCF30 combines the toughness and flexibility of TPU with the rigidity and conductivity of long carbon fibers, offering a unique balance of performance and processability.

Key Advantages

High Strength-to-Weight

Exceptional mechanical performance with low density, enabling lightweight structural components without compromising durability.

Thermal Stability

Maintains properties up to 135°C (HDT), with excellent heat resistance for under-hood and high-temp industrial applications.

Electrical Conductivity

Volume resistivity < 10³ Ω·cm provides reliable ESD protection, ideal for electronics and sensitive equipment.

Dimensional Precision

Low warpage, excellent mold replication, and consistent shrinkage ensure tight tolerances for complex injection-molded parts.

Performance Edge: Long Fiber vs. Short Fiber

TPU LCF30 (long carbon fiber) vs. TPU CF30 (short carbon fiber) - same 30% loading, dramatically different performance.

TPU LCF30 (long carbon fiber) vs. TPU CF30 (short carbon fiber)

TPU LCF30 (Long Fiber) TPU CF30 (Short Fiber) • Higher values indicate better performance

FAQ

Q: Why choose TPU LCF30 over TPU CF30 for high‑load structural parts?

A: Long carbon fibers create a continuous reinforcing network that dramatically improves creep resistance, stiffness retention at elevated temperatures, and fatigue endurance. TPU LCF30 retains superior mechanical properties under sustained loads, with up to 40% higher tensile strength and 50% higher flexural modulus compared to short‑fiber TPU CF30, while offering excellent ESD protection and dimensional stability.

Q: Can TPU LCF30 replace metal in automotive and industrial applications?

A: Absolutely. TPU LCF30 offers a strength‑to‑weight ratio comparable to aluminum, with excellent corrosion resistance, design flexibility, and the ability to consolidate multiple metal parts into a single injection‑molded component. It reduces weight by up to 60% versus steel and 30% versus aluminum, while providing inherent electrical conductivity for ESD‑sensitive assemblies.

Q: What are the recommended processing conditions for TPU LCF30?

A: Pre‑dry at 80–100°C for 4–6 hours (moisture < 0.02%). Melt temperature 190–220°C, mold temperature 40–60°C. Use a metering screw with L/D ≥ 20:1 and a free‑flow check valve to minimize fiber breakage. Avoid excessive residence time and shear. Regrind up to 20% can be reused with property verification.
