PEEK Polyether Ether Ketone Film

PEEK film: polyether ether ketone (English Poly-Ether-Ether-Ketone, referred to as PEEK) is in the main chain structure contains a ketone bond and two ether bond repeating unit composed of polymers, is a special polymer materials. With high temperature resistance, self-lubricating, chemical corrosion resistance, irradiation resistance, easy processing, small coefficient of thermal expansion, good dimensional stability and other physicochemical properties, is a class of semi-crystalline polymer materials, melting point 343 ℃, Tg = 143 ℃, its loaded heat distortion temperature of up to 315 ℃, instantaneous use of the temperature up to 300 ℃. Tensile strength 132~148MPa, density 1.265 (amorphous) ~ 1.320 (crystalline) g/cm3; the maximum crystallinity of 48% can be achieved, usually 20~30%, impact strength (notched) 60~80J/m; elongation at break ≥150%; water absorption ≤ 0.1%; volume resistivity 1016Ω-cm; bending strength ≥140MPa Dielectric constant 3.2~3.3; tensile strength ≥93MPa; flame retardant (UL94) V-0, continuous working temperature up to 220 ℃, can be used as high temperature resistant structural materials and electrical insulation materials, can be composite with glass fiber or carbon fiber to prepare reinforced materials. This material has a large number of applications in the aerospace field, medical device field (as artificial bone repair bone defects) and industrial field, known as the tip of the pyramid of the plastics industry.

 

PEEK film properties:

 

PEEK film is produced by thermoplastic molding of the super engineering plastic PEEK resin, and is divided into two types: low-crystalline and high-crystalline. PEEK film has the following distinctive characteristics:

 

Mechanical properties: toughness and rigidity and balance of the plastic film, with excellent fatigue resistance, comparable to alloy materials.

 

High Temperature Resistance: Resistant to the temperatures of lead-free soldering processes, with RTI ratings of 220°C for non-shock mechanical applications and 200°C for electrical applications, and a carbonization point that remains stable up to 500°C.

 

Self-lubrication: excellent sliding characteristics, suitable for strict requirements of low coefficient of friction and wear-resistant applications, especially carbon fiber, graphite, each accounted for a certain percentage of mixed modified PEEK film self-lubricating performance is better.

 

Chemical resistance (corrosion resistance): excellent chemical resistance, in the usual chemicals that can dissolve or destroy it is only concentrated sulfuric acid, its corrosion resistance is similar to nickel steel.

 

Flame retardant: very stable polymer, without adding any flame retardant can achieve high flame retardant standards, halogen-free, in line with IEC 61249-2-21 standard.

 

Stripping resistance: very good stripping resistance, can be made into very thinly wrapped solenoid wires, and can be used under harsh conditions.

 

Fatigue resistance: Excellent fatigue resistance.

 

Irradiation resistance: very strong resistance to high irradiation, and still maintains good insulation ability under ultra-high irradiation dose.

 

Hydrolysis Resistance: Unaffected by the chemical effects of water and high-pressure water vapor, the products made from this film material can still maintain their excellent characteristics when used continuously in high-temperature and high-pressure water.

 

Meltability: Fuses with metal when it reaches a temperature above the melting point, ultrasonic sealing is easy (PET film can also be sealed), and laser dissolving and printing are possible.

 

High sound clarity: Avoiding the “hearing fatigue” caused by metallic film noise, better acoustic performance is realized.

 

Environmentally friendly and safe: lightweight, recyclable, RoHS compliant, can be used to manufacture products that comply with the same directive, and meets the requirements of the U.S. Food and Drug Administration (FDA).

 

Wide range of thickness options: films with a thickness of 4~300μm can be produced and customized according to customer needs.
