Why is PEEK the ideal material for manufacturing industrial seals?

When you talk to an industrial seal manufacturer about the best sealing material, chances are he will say PEEK (polyether ether ketone). When it comes to industrial polymers, PEEK is known for its unique properties and durability. But, as a customer, should you also choose PEEK? What makes this polymer so different from others? Let's learn about PEEK.

Understand the characteristics of PEEK material

PEEK is an engineering plastic that combines high mechanical properties, temperature resistance (-50°C to +250°C) and excellent chemical resistance, with excellent wear resistance, very high mechanical properties, dimensions and creep Variable stability, even under thermal load. With excellent chemical resistance and an operating temperature of up to 260°C, it is often used to make components that are lighter, stronger and able to perform in the harshest environments.

Resistant to many chemicals: PEEK performs even in the harshest chemical environments. It is resistant to more than 140 acids, oils, liquids, salts and elements.

Extremely high temperature resistance: The polymer has a high melting point of 343°C, therefore, it can easily operate at temperatures up to 250°C. Therefore, if you need a polymer product that can withstand high temperatures, PEEK is the material of choice.

Extended Resistance to Hydrolysis Process: Hydrolysis refers to the chemical process of adding water to a substance. Due to the previously mentioned properties, PEEK is able to withstand prolonged exposure to steam and water without degradation.

Excellent Durability: Physically, PEEK is tough, stiff and very strong. It is able to provide friction where necessary and can run for a long time without suffering wear and tear.

Manufacturing Flexibility: As a material, PEEK is also ideal for plastic injection molding and machining. A wide variety of industrial components and products can be produced using this polymer.

Learn about the benefits of PEEK seals

PEEK is an ideal material for seal production. Since it is an organic thermoplastic polymer, the material has excellent properties in terms of mechanical and chemical resistance. Furthermore, these properties are maintained even at high temperatures. You can thus heat, cool and reheat PEEK seals without any degradation, making them suitable seals for process technology and equipment or even the food industry. Most seal manufacturers always recommend PEEK as a seal material for extremely demanding industries. These include oil and gas, mining, aerospace, heavy equipment and renewable energy.
