Product introduction

ARCHCELL® HT

ARCHCELL® is a closed-cell rigid PMI (Polymethacrylimide) foam, which used as the core of lightweight sandwich structure.

HT(High Temperature) grade is suitable for high temperature curing epoxy resin system and can be compatible with the process conditions of 130℃ and 0.7MPa, and can be compatible with the process conditions up to 180℃ and 0.7MPa after heat treatment (based on density), and it is suitable for various curing processes (Autoclave, vacuum infusion, RTM, VARTM, VARI, HP-RTM, etc.). It also can be easily thermoformed or CNC machined.

The cell size is an important specification of the foam material and determines the difference in the amount of curing resin absorbed during the foam processing. We have divided it according to the cell size in order to better fit the different processing processes.

TYPICAL PROPERTY VALUES

ARCHCELL® HT-FC

FC is a fine cell structure that guarantees a lowest curing resin absorption of up to 50g/m2, thus reducing the weight of the final product, and is particularly suitable for vacuum infusion and RTM processes.
