VICTREX® APTIV® 1000 PEEK Disk

VICTREX® APTIV® 1000 PEEK Disk is an unfilled PEEK film converted into a circular, thin insulating part that blends toughness, chemical resistance, and long‑term heat stability for compact assemblies. It suits washers, diaphragms, and masks in stacks where cleanliness and low moisture uptake matter, and it avoids halogens for compliance in sensitive environments. Aerospace, electronics, and analytical instruments use it to manage heat and prevent electrical shorts without adding weight or compromising purity. The disk cuts cleanly, resists tearing, and holds shape through thermal cycling, supporting repeatable die‑cut parts at scale. It also bonds and laminates well for multi‑layer builds. For teams seeking a high‑purity dielectric in a simple format, APTIV 1000 delivers dependable performance and smooth integration with adhesives, foils, and fasteners across development and production.
