Zotek® F
Lighter, cleaner, more efficient foams offering unique advantages in a host of aviation and aerospace applications
Introduction
Zotek® F is a family of closed-cell, polyvinylidene fluoride (PVDF) foams manufactured by Zotefoams and distributed by Insul-Fab for aviation, aerospace, and high-performance industrial applications. Produced through Zotefoams' proprietary nitrogen expansion process — free of chemical blowing agents and residues — Zotek F foams deliver a uniquely clean, consistent cellular structure with excellent mechanical properties and a lightweight profile.
The defining characteristic of Zotek F is its compliance with FAA and aviation industry flammability standards, including OSU heat release (FAR/CS 25.853(d) App F Pt IV), smoke density, toxic gas emission (ABD0031), radiant heat panel (FAR 25.856(a)), and vertical burner tests. Available in flexible, semi-rigid, and rigid grades across a range of densities and temperature ratings, Zotek F is thermoformable into complex shapes for direct integration into aircraft interior assemblies and other aerospace components.

APPLICATIONS
Zotek F is used across a broad range of aerospace and aviation applications where FAA flammability compliance, light weight, and thermoformability are critical:
- Aircraft cabin interior components — seat cushions, armrests, headrests, and comfort pads requiring FAA OSU heat release compliance
- Wall panels, ceiling liners, and overhead bin padding — lightweight, thermoformed foam components meeting aviation smoke and toxic gas standards
- Acoustic insulation in aircraft cabins — noise attenuation with compliant flammability performance
- Thermal insulation in aerospace assemblies — low thermal conductivity for temperature management in confined spaces
- Formed and contoured parts — thermoformed to complex geometries for close-fit installation in fuselage and interior assemblies
- Galley and lavatory insulation — chemical-resistant PVDF foam suitable for areas with fluid exposure
- High-performance industrial applications requiring a clean, residue-free closed-cell foam with elevated temperature resistance
