Product description

Toray MicroPly™ EX-1541 cyanate ester syntactic foam is extremely unique in the industry due to its coupling of extremely low density and good structural properties. If packed well, the material does not require pressing during cure to achieve it mechanical properties and is easily machined to shape if required. Toray MicroPly™ EX-1541 is simply packed or injected into tooling cavities and can also be extruded with the proper tooling.

Toray MicroPly™ EX-1541’s inherently low dielectric/low loss performance makes it ideal for radomes, antennae, and radar transparent structures, while its cyanate ester backbone chemistry assures low moisture absorption and low outgassing. These latter two features coupled with it’s low isotropic CTE make it ideal for spacecraft and other dimensionally stable structures and tooling.

Toray MicroPly™ EX-1541 can be accurately machined and hand-finished. Sanding and fairing is easily performed on cured it and is similar to working with balsa wood. Variants from 176–384 kg/m³ (11–24 lb/ft³) (pcf) are available.
