PEEK Products

PEEK – Polyether Ether Ketone
Polyether Ether Ketone (PEEK) is a high-performance thermoplastic known for its exceptional mechanical strength, toughness, hardness, flexural strength, and torsional strength.

PROPERTIES OF PEEK

PEEK has a range of impressive properties that make it suitable for demanding applications:

• Very high mechanical strength: Ideal for applications requiring robust materials.

• Very high rigidity: Retains its rigidity even at elevated temperatures.

• Very high thermal stability: Maintains properties up to +480 °F.

• Very high dimensional stability: Exhibits minimal expansion or contraction with temperature or environmental changes.

• Very high radiation resistance: Suitable for challenging environments with high radiation.

• Very high hydrolysis resistance: Highly durable in moist or wet conditions.

• Notch impact strength relatively low: While strong, has lower notch impact resistance than some materials.

• Low resistance to acetone: Limited compatibility with acetone.

• High wear resistance at higher temperatures: Maintains excellent wear resistance even when hot.

Due to its exceptional properties, PEEK is used in a variety of industries and applications:

• Bearing shells – for high strength and durability

• Piston rings – due to thermal stability and wear resistance

• Valve seats – ideal for heat and chemical resistance

• Gears – thanks to rigidity and mechanical strength

• Seals – for chemical resistance and longevity

• Aviation components – lightweight yet strong

• Pump vanes – durable and wear-resistant

• Fittings – due to chemical resistance and strength

• Plug connectors – owing to electrical insulation properties

• Wafer carriers – used in semiconductor industry for thermal stability and chemical resistance

• Semiconductor applications – due to radiation resistance and thermal endurance
