Product introduction
ARCHCELL® UT
ARCHCELL® is a closed-cell rigid PMI (Polymethacrylimide) foam, which used as the core of lightweight sandwich structure.
UT (Ultra-high Temperature) can withstand very demanding process conditions in all ARCHCELL® portfolio, up to 180 °C and 0.45 MPa for conventional grades and even 190 °C and 0.7 MPa after heat treatment. typical curing temperatures for BMI resin systems are up to 210 °C (410 °F) for pressureless post-curing processes. And it is suitable for a variety of curing processes (autoclave, vacuum infusion, RTM, VARTM, VARI, HP-RTM, etc.). It also has good processability and 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 various processes and resin viscosities.
TYPICAL PROPERTY VALUES
ARCHCELL® UT-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.
