Description

The product is an aramid polymer with a particularly stable molecular structure. It is obtained from different forms of aramid polymer.


Non-metallic honeycombs are manufactured from high temperature resistant aramid paper formed into a honeycomb structure and coated with a phenolic resin. The combination of aramid paper and phenolic resin gives commercial and aero grade of honeycomb with superior strength, toughness and chemical resistance.


The honeycomb cell shapes are normally hexagonal for optimum mechanical properties. It can also be over-expanded to produce a rectangular cell shape and provide improved drapeability for the production of curved parts.
