PEEK Films
PEEK (polyether ether ketone) film is a flexible film made of high-performance PEEK resin. It inherits the inherent characteristics of PEEK material and is presented in extremely thin form. Dalian Allstar Material can provide peek film with thickness of 0.03mm-3mm and width of 30mm-600mm, which can be produced according to customers' requirements.
PEEK Films Production process and advantages
Dalian Allstar adopts advanced casting process. The main steps include:
First, dissolve the PEEK resin in a specific solvent to form a uniform, viscous solution.
Second, the solution is passed through a die head and uniformly cast on a continuously running smooth roller.
Third, the solvent is evaporated by a controlled heating and drying system, leaving a uniform, dense PEEK film.
Finally, it is wound and cut.

The advantages of the cast process are:
Casting offers key benefits such as the ability to create complex shapes, handle large-sized components, and use a wide range of metals. Its cost-efficiency and minimal material waste make it ideal for mass production and diverse industrial applications.
Uniform thickness
Flat and smooth film surface.
Uniform thickness
Suitable for wide film widths.
Better control of the orientation of the polymer molecular chains, contributing to stable physical properties.

Highlights of PEEK Film
PEEK film is a high-performance thermoplastic known for its exceptional strength, heat resistance, and chemical durability, making it ideal for demanding applications in aerospace, electronics, and medical industries.

Temperature Range
Long-term stability over a wide range of temperatures from -40°C to +250°C (-40°F to +482°F).
Short-term use temperatures can exceed 300°C(572°F).

Low Density
has a standard density of approximately 1.30 - 1.32 g/cm³, which facilitates lightweight design.

High Mechanical Strength & Stiffness
maintains excellent tensile strength (typically >90 MPa) and modulus of elasticity (~3.7 GPa) at elevated temperatures to ensure structural integrity.

Excellent Wear Resistance
Low coefficient of friction and good wear resistance, especially for dynamic or friction applications.

Outstanding Chemical Resistance
exhibits excellent resistance to chemicals, including a wide range of strong acids, alkalis, solvents, hydrocarbons, as well as hot water and pressurized steam, and is not susceptible to corrosion or degradation.

Excellent Fatigue Resistance
is not prone to fatigue rupture, ensuring long term use. PEEK's fatigue resistance is significantly better than that of polyamide (PA), polyoxymethylene (POM), polyester (PET/PBT), etc., especially at high temperatures and in chemically corrosive environments.

Other key properties
electrical insulation, low flammability (UL94 V-0 rating), low outgassing, and good radiation resistance.
PEEK film application
With the excellent performance of peek film, PEEK film is widely used in many fields:

Case 1: Electrical & Electronic Insulation
high dielectric strength, excellent high temperature resistance, good flexibility, chemical resistance.
Applications
high performance wire and cable winding insulation, flexible printed circuit board (FPC) substrate or cover film, motor slot insulation, transformer interlayer insulation.

Case 3: Aerospace & Automotive Industries
Lightweight, high temperature, chemical (fuel, lubricant) resistant, high strength, low outgassing.
Applications
Lightweight and durable thermal/acoustic barrier materials, barrier or vacuum bagging films for high performance composite manufacturing, wear gaskets, specialty sensor diaphragms.
