PPS-LCF60 | 60% Long Carbon Fiber Reinforced Polyphenylene Sulfide

PPS-LCF60 is an elite performance, semi crystalline thermoplastic composite reinforced with 60% long carbon fiber, engineered for maximum structural strength, stiffness, and dimensional precision under extreme thermal, mechanical, and chemical exposure. With its ultra high carbon fiber loading, PPS-LCF60 pushes the boundaries of polymer based engineering materials, offering metal equivalent performance at a significantly lower weight.

Compared to lower fiber content grades like PPS-LCF40 and PPS-LCF50, PPS-LCF60 provides superior load retention, creep resistance, and fatigue durability even under continuous high temperature stress and harsh chemical conditions. It is the material of choice for mission critical components requiring long service life, tight tolerances, and unwavering mechanical stability.

Core Performance Highlights

Mechanical Properties

Carbon Fiber Content: 60% (long chopped fibers, densely packed and aligned during molding)

Tensile Strength: ≥ 230–240 MPa

Flexural Modulus: ~24–26 GPa

Elongation at Break: ~0.5–0.8%

Notched Izod Impact: ~30–40 J/m

→ The highest fiber content in the PPS-LCF series yields exceptional stiffness, maximum mechanical load capacity, and metal like strength, ideal for advanced lightweighting in extreme use environments.

Thermal Resistance

Heat Deflection Temperature (HDT): ≥ 285 °C

Continuous Use Temperature: Up to 260 °C

→ Delivers outstanding thermal stability for long term operation under elevated and cycling temperatures, with minimal distortion or creep.

Environmental & Chemical Durability

Moisture Absorption: <0.01% — near zero, enabling excellent dimensional control

Chemical Resistance: Outstanding — highly resistant to acids, bases, fuels, oils, and industrial solvents

→ Maintains full mechanical and dimensional performance in corrosive, submerged, or chemical processing environments.

Processing & Manufacturing

Molding Methods: Long fiber injection molding (LFT-G), compression molding

Surface Finish: Matte to rough; fiber exposure is prominent

Tooling Requirements: Requires hardened, abrasion resistant tooling (ceramic coated or hardened steel) due to high wear from fiber content

→ Optimal processing requires tight control of fiber orientation, filling pressure, and cooling profile to preserve long fiber integrity and achieve maximum structural performance.

Target Applications

Automotive & Mobility

Engine crossmembers, underbody frames, suspension linkages

→ Replaces cast metal in high load zones with exposure to heat, vibration, and chemicals, enabling lightweight, corrosion resistant designs.

Aerospace & Defense

Load bearing structures, thermally insulated mounts, high strength brackets

→ Combines maximum stiffness, chemical stability, and thermal resistance for flight critical or weight sensitive components.

Industrial & Mechanical Systems

Structural frames, robotic load arms, process equipment housings

→ Ideal for vibration intensive, high wear, or chemically aggressive environments with long service demands.

Electronics & Electrical Systems

Power module frames, high temp battery supports, rigid EMI shielding

→ Ensures mechanical strength, thermal endurance, and precise dimensional control in high voltage, high temperature electronics.
