PPS-LCF30 | 30% Long Carbon Fiber Reinforced Polyphenylene Sulfide

PPS-LCF30 is a top-tier, semi-crystalline thermoplastic composite reinforced with 30% long carbon fiber, designed for structural, high load, and high temperature applications that demand superior stiffness, strength, and dimensional stability. With its high long fiber content, PPS-LCF30 offers metal like mechanical performance while retaining the exceptional chemical resistance and thermal stability characteristic of PPS.

Compared to lower LCF grades such as PPS-LCF10 and PPS-LCF20, this material delivers markedly improved fatigue resistance, creep performance, and load transfer efficiency, making it ideal for mission critical components exposed to thermal cycling, mechanical vibration, or chemically aggressive environments.

Core Performance Highlights

Mechanical Properties

Carbon Fiber Content: 30% (long chopped fibers, well aligned during molding)

Tensile Strength: ≥ 170–180 MPa

Flexural Modulus: ~14–16 GPa

Elongation at Break: ~0.8–1.2%

Notched Izod Impact: ~45–55 J/m

→ The higher fiber volume fraction delivers exceptional stiffness and structural rigidity, suitable for replacing aluminum and other metals in weight sensitive or fatigue critical applications.

Thermal Resistance

Heat Deflection Temperature (HDT): ≥ 260 °C

Continuous Use Temperature: Up to 230 °C

→ Maintains mechanical integrity and dimensional accuracy in high temperature environments with low creep and minimal warping, even under continuous thermal stress.

Environmental & Chemical Durability

Moisture Absorption: <0.02% — extremely low, ensuring tight dimensional control

Chemical Resistance: Excellent — withstands exposure to fuels, oils, acids, bases, and solvents

→ With reliable resistance to moisture, corrosion, and chemical degradation, PPS-LCF30 is well suited for submerged or chemically active environments.

Processing & Manufacturing

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

Surface Finish: Matte to textured surface; visible fiber patterns may be present

Tooling Requirements: Requires abrasion resistant, high temperature tooling due to increased fiber content

→ Proper processing setup is essential to preserve fiber length, ensure uniform distribution, and maximize mechanical properties. Higher CF content increases tool wear but dramatically enhances part performance.

Target Applications

Automotive & Mobility

Structural engine covers, crossmembers, transmission brackets

→ Combines weight savings with metal equivalent stiffness for under hood or powertrain structures exposed to thermal and mechanical stress.

Aerospace & Defense

Lightweight structural frames, load bearing brackets, thermal isolators

→ Delivers high performance alternatives to metal in applications requiring fatigue resistance, chemical resilience, and weight reduction.

Industrial & Mechanical Equipment

Reinforced housings, couplings, wear pads, valve components

→ Ideal for dynamic or corrosive environments, ensuring long term performance and geometric stability under stress.

Electronics & Electrical Systems

Rigid PCB carriers, power system enclosures, shielding frames

→ Provides a strong, thermally stable structure for high voltage and electronic power applications.
