Zotek® N
High performance closed cell, cross-linked Nylon foam based on Polyamide 6.
Introduction
Zotek® N is a family of closed-cell, cross-linked polyamide (Nylon PA6) foams manufactured by Zotefoams and distributed by Insul-Fab for applications requiring exceptional high-temperature performance. Produced through Zotefoams' proprietary nitrogen expansion process, Zotek N foams are free of chemical blowing agent residues and deliver a uniform, pure cellular structure with outstanding mechanical properties at elevated temperatures.
With maximum operating temperatures ranging from 374°F to 401°F (190°C–205°C), Zotek N significantly outperforms conventional polyolefin and polyurethane foams in demanding thermal environments. The material is thermoformable into complex shapes and available in multiple densities, making it well-suited for automotive under-hood components, high-temperature industrial gasketing, and other applications where standard foams fall short.

Features
- Closed-cell cross-linked polyamide (Nylon PA6) construction — superior heat resistance vs. conventional foams
- Manufactured via nitrogen gas expansion — no chemical blowing agent residues for exceptional purity
- High maximum operating temperatures: ND35 rated to 374°F (190°C), NB50 rated to 401°F (205°C), NB70 rated to 400°F (204°C)
- Excellent mechanical strength at elevated temperatures — retains structure where polyolefin foams would deform
- Multiple densities: ND35 at 38 kg/m³, and higher-density NB grades for increased load-bearing performance
- Thermoformable into simple and complex three-dimensional shapes
- Closed-cell structure provides low moisture absorption and good chemical resistance
- Excellent compression resistance and resilience
- ISO 9001:2015, OHSAS 18001, and ISO 14001 certified manufacturer (Zotefoams)
APPLICATIONS
Zotek N is suited for applications where conventional foams cannot withstand sustained operating temperatures or require a high-purity closed-cell structure:
- Automotive under-hood components — heat shields, insulators, and gaskets in engine bay environments up to 400°F+
- High-temperature gasketing and sealing — closed-cell foam gaskets for industrial equipment, HVAC, and process machinery
- Thermal insulation in high-heat environments — pipe wrap, equipment insulation, and heat management in industrial settings
- Formed and contoured insulation parts — thermoformed shapes for close-fitting thermal barriers in tight assemblies
- Electrical insulation — Nylon's inherent dielectric properties combined with high-temperature resistance
- Transportation and rail — thermal and acoustic insulation components requiring elevated temperature ratings
- Aerospace ground support equipment — high-temp foam components outside FAA cabin interior scope
- Replacement for polyurethane and polyolefin foams where heat resistance and cleanliness are required
