PEEK Sheet

PEEK polymer is renowned as one of the highest performing materials globally, offering a unique combination of properties. PEEK Sheet excels in high-temperature performance, displays excellent chemical and wear resistance, and is biocompatible. With a tensile strength of 90 to 100 MPa, PEEK Sheet can withstand demanding conditions. It boasts a high melting point of around 343°C, surpassing PTFE or PPS, and can operate at a continuous service temperature of 260°C. Moreover, PEEK Sheet is highly resistant to thermal degradation and immune to attacks by both organic and aqueous environments.

The main disadvantage lies in the relatively high price of PEEK, nearly four times that of PTFE, which often restricts its use to high-value items. Another drawback is that PEEK is not a shape memory polymer, meaning it lacks the ability to return to its original shape after temporary deformation through an external stimulus.

PEEK Sheet boasts remarkable hardness, being 53% harder than Acetal, and possesses 36% more tensile strength than nylon 6,6, making it almost 60% stiffer. It excels in high-temperature applications, with a short-term operating temperature of 300°C, surpassing PTFE by 40 degrees. PEEK Sheet is known for its excellent machine-ability, flame retardancy, and exceptional wear and slide properties.

PEEK Sheet's exceptional strength makes it ideal for fabricating items used in demanding applications, such as bearings, piston parts, pumps, HPLC columns, compressor plate valves, and cable insulation. It is extensively utilised in aerospace, automotive, and chemical process industries, as well as train and underground applications. Moreover, PEEK serves as a metal replacement for high-temperature uses and has become crucial in the oil and gas industry for drilling and production. Additionally, PEEK plays a superior role in alternative energy production, contributing to the construction of solar, wind, nuclear, geothermal, and hydropower equipment and components.

PEEK Sheet's stiffness decreases significantly, and its expansion rate increases above 150°C. For applications requiring close tolerance bearings or seals operating at temperatures higher than 150°C, an alternative material like PAI (polyamide-imide) may be a better choice.

PEEK Sheet must undergo stress-relief through an annealing process before machining to prevent surface cracks and internal stresses. Silicon carbide cutting tools are recommended for natural PEEK Sheet, and machining dry is best to preserve its biocompatibility. If needed, pure water coolant may be used to remove cutting heat that builds up, as PEEK doesn't dissipate heat like metals.

PEEK Sheet is challenging to bond due to its low surface energy. Depending on the adhesive used, surface roughening may improve bond strength.

All unfilled PEEK grades comply with FDA regulations for repeated food contact.

PEEK Sheet exhibits very good abrasion and high wear resistance.

PEEK Sheet material demonstrates resistance to a wide range of chemicals and solvents.

PEEK Sheet exhibits exceptional radiation resistance, absorbing over 1000 units of radiation with no significant loss of mechanical properties.

PEEK is also known by other trade names, including Victrex® PEEK, Arlon®, and Ketron®.

PEEK Sheet material is available in natural (off-white) colour and comes in sheet thicknesses ranging from 5 mm up to 80mm.

PEEK polymer is celebrated as one of the highest performing materials globally. Its versatility makes it suitable for fabricating items used in demanding applications across various industries.

While PEEK Sheet excels in high-end applications, its cost can be prohibitive for most low-end or low-cost components.

PEEK is a unique, high-temperature, high-performance engineering plastic. Its exceptional properties make it tough, rigid, and remarkably strong, with excellent chemical and radiation resistance. PEEK's applications are extensive, from steam and high-pressure water environments to vacuum conditions, where it shows no significant degradation. The material's smoke and toxic acid gas release during combustion are the lowest of any thermoplastic. PEEK's insolubility in common solvents and resistance to a wide range of organic and inorganic liquids, even at high temperatures, further add to its versatility.
