Description

PEEK is a lightweight and strong semi-crystalline thermoplastic. Due to its high melting point and low coefficient of thermal expansion, PEEK has high dimensional stability. As such, PEEK food handling products can withstand microwave use, dishwasher use, and intense temperatures when cooking directly on heat.

Structure

Melting Point

343 °C (649 °F; 616 K)

Purity

90%

Density

1320 kg/m³

Application

PEEK is safe for direct contact with delicate foods like raw lettuce or fresh dairy products even during the production process. For this reason, PEEK food handling components are used in both food packaging and food production processes. Some common products made from PEEK resin include blenders, kneaders, mixing paddles and scrapers, and valves and nozzles on coffee machines.

Chemical Formula

C19H14O3

Feature

PEEK is a polyaromatic semi-crystalline thermoplastic polymer with mechanical properties favorable for bio-medical applications. PEEK outpaces other food-safe plastics in terms of design flexibility. PEEK can be manufactured with added colorants to make it a vibrant color, which increases process safety since broken or damaged PEEK parts will be immediately noticeable during production. This helps prevent hazardous food and beverage consumption and accidental contamination.

Tensile Strength

90-100 MPa

Thermal Conductivity

0.25 W/(m⋅K)

Volume Resistivity

16-17 x 10¹⁵ Ohm.cm
