CNC PEEK (Polyether ether ketone)
PEEK is an advanced thermoplastic material, considered a technopolymer due to its outstanding mechanical properties and chemical resistance.
Polyether ether ketone (PEEK) is a colorless organic thermoplastic polymer and belongs to the <polyaryletheketone family.
POLYETHERETHERKETONE PROCESSING (Milling – Turning - Broaching)
It is suitable for use in a wide range of temperatures, including both hot and cold, and is used in many industries including food, aerospace, automotive, military defence, electronics, petrochemicals, nuclear, hydroelectric, biomedical and cable manufacturing.
This technopolymer is considered to be one of the most versatile and performing in critical applications such as mechanics, aviation and petrochemicals, thanks to its high temperature resistance and low permeability to aggressive substances. Compared to other plastics, it has the highest coefficient of tensile strength and it can remain functional at temperatures up to 250°C for a long period of time without losing its properties.
Almatech is specialized in the machining of PEEK customized components, including:
Bushes, Spacers, Nozzles, Plates, Blades, Pads, Plugs/Caps, Scrapers, Blocks, Supports, Anchor fixings, Balls, Impellers, Valves seats, Pistons, Oven grippers and many other components.
PEEK fields of application
Mechanical industry
Frequently used in the mechanical industry to produce bearings, spring rings, gears, bushings, automotive engine components, rolls valve seats, conveyor components, pump parts, compressor rings and other components.
Food industry
The use of PEEK in food and beverage production and processing is approved by both EU and FDA regulations.
Medical industry
PEEK is a widespread choice in the medical industry due to its biocompatibility and outstanding physical, chemical and mechanical properties.
Electronics industry
Due to its outstanding dielectric and insulating properties, PEEK is commonly used in the electronics and semiconductor industry.
Chemical industry
Due to its good resistance to compounds and inability to dissolve in major solvents, such as acids, salts and oils, PEEK is commonly used in chemical industry.
Nuclear industry
Due to its high resistance to gamma radiation, PEEK is commonly used in nuclear industry too.
automotive industry
Due to its outstanding chemical properties, PEEK is the perfect material for automotive and motorsport applications.
Aerospace industry
PEEK light weight, strength and reliability make it a must for improving performance, efficiency, and safety in aerospace industry.
FILLED PEEK
This polymer material can be upgraded with the addition of small amounts of PTFE, graphite and carbon fibre. These nanoparticles enable the material to retain its superior properties, to acquire a high mechanical resistance as well as to withstand to wear, abrasion and tearing.
Natural PEEK-GF30 (burnished grey)
PEEK-GF30, polyether ether ketone filled 30% glass fibre, has a higher level of rigidity, dimensional stability and creep resistance compared to base polymer PEEK. This material offers its best performance in static structural applications that require to withstand heavy static loads at high temperatures. On the other hand, its use in sliding applications must be carefully evaluated due to the presence of glass fibres that can cause an abrasive effect on the counterpart.
PEEK-CA30 black
PEEK-CF30, polyether ether ketone filled 30% carbon fibre, has higher mechanical properties compared to PEEK-GF30, including a higher rigidity and creep resistance, as well as an outstanding wear resistance. Furthermore, carbon fibers increase thermal conductivity by 3.5 times compared to virgin PEEK, allowing for rapid heat dissipation from the sliding surface.
