Metal-Detectable PEEK Bars

Common in food and pharmaceutical plants, these PEEK bars help you identify contaminated batches. They contain metal and chemical additives that set off metal detectors and show up on X-rays if they fall into your line, which help you comply with Hazard Analysis and Critical Control Point (HACCP) programs. All are bright blue in color, so you can find and remove them quickly. They’re also FDA compliant for direct contact with food.

These PEEK bars stand up to wear from abrasion and repetitive processes. They’re also resistant to extended contact with water, high-temperature steam, and clean-in-place (CIP) cycles with harsh cleaners and sanitizers. Due to their light weight, they’re commonly substituted for metal parts in high-stress or chemical-processing applications where weight is important.

Machinable PEEK Sheets

These PEEK sheets can be machined to tight tolerances for use in electrical and semiconductor parts, such as test sockets. With a ceramic filler, they have excellent hardness and rigidity. The filler also acts as an effective barrier against gas and fluid permeation. These sheets maintain their shape when exposed to temperature changes. They also withstand wear from abrasion and repetitive processes.
