PEEK CA SHEET AND ROD

PEEK CA (carbon fiber reinforced polyetheretherketone) is a high-performance modified composite material, composed of PEEK resin and short-cut or continuous carbon fiber (usually 30%). Its core performance is high strength, high rigidity, excellent high temperature resistance, and conductivity while retaining the gravity resistance and lightweight advantages of PEEK. It is widely used in high-end fields such as aerospace, automobile, and electronics.​

PEEK CA SHEET HIGHER STRENGTH

Product Advantages

High Strength: Tensile Strength 200-250 MPa (90-120 MPa for pure PEEK), Flexural Modulus 8-10 GPa (3-4 GPa for pure PEEK).

High Heat Resistance: Heat Deformation Temperature (HDT) reaches 240°C (1.82MPa load), short-term resistance 260°C.

Conductivity: Carbon fiber gives the material conductivity (surface resistivity 10³-10⁵Ω/sq), avoiding static electricity accumulation.

Lightweight: Density 1.4-1.6 g/cm³, more than 50% lighter than aluminum.

Corrosion Resistance: Resistant to strong acids, strong alkalis, organic solvents and high-temperature steam.

Environmental Compliance: Halogen-free, UL94 V-0 flame retardant, ISO 10993 medical certification.

Scope of application and specific applications

Automotive industry: turbocharger impeller, sensor housing, ignition system bracket.

Aerospace: lightweight structural parts, fuel system connectors, high temperature resistant gaskets.

Electronic and electrical: high frequency connectors, antistatic tool housings, chip carriers.

Industrial equipment: explosion-proof equipment housings, robot arms, bearing cages.

Precautions

Processing temperature: Avoid exceeding 380°C to prevent PEEK degradation or carbon fiber breakage.

Mold design: It is necessary to add exhaust grooves (depth 0.02-0.04mm) to prevent trapped air from burning.

Recycling: It cannot be melted and regenerated, and can only be crushed for filler or industrial waste treatment.

Safety protection: Carbon fiber dust is generated during processing (long-term inhalation is harmful to the lungs), and dust masks must be worn.

OVERVIEW of PEEK - 30% Carbon-Filled

Peek 30% carbon-filled is 30% carbon fiber reinforced polyetheretherketone which is either extruded or compression-molded. The addition of carbon fibers enhances the compressive strength and stiffness of PEEK, and dramatically lowers its expansion rate. It offers designers optimum wear resistance and load carrying capability in a PEEK-based product. This grade provides 3-1/2 times higher thermal conductivity than unreinforced PEEK--dissipating heat from the bearing surface faster.
