In the world of industrial gaskets, choosing the right material is a strategic decision. For this reason, World Gasket Ellegi uses PEEK (Polyetheretherketone) in the production of its seals for engine transmissions in earth-moving machinery, chosen for its outstanding performance in complex operating environments.

Why Choose PEEK for industrial applications

PEEK is an organic, high-performance thermoplastic polymer, widely used in sectors where materials with high mechanical strength, thermal stability, and chemical resistance are required.

Thanks to these properties, it represents an ideal solution for:

• High-temperature environments;
• Applications exposed to aggressive chemicals;
• Conditions involving heavy mechanical stress;
• Systems requiring long service life and low maintenance.

Technical properties of PEEK

• High tensile strength (up to 29,000 psi);
• Operating temperature up to 260°C, melting point at 341°C;
• Dimensional stability even under heavy loads;
• Excellent resistance to wear, abrasion, and chemicals;
• Low flammability with minimal smoke emission;
• Outstanding electrical insulation.

PEEK in the WGE product range

Within the World Gasket Ellegi range, PEEK is used for specific types of seals in engine transmissions for earth-moving machinery, where maximum resistance, precision and long-term reliability are essential.

Choosing this material allows our customers to benefit from:

• Reduced downtime and greater production continuity;
• Longer component life even under extreme conditions;
• Consistent quality in every batch.
