Toray MicroPly™ SC72A

1 of 21 products in this brand
Toray Toray MicroPly™ SC72A is a 120°C (248°F) curing low-density unsupported epoxy syntactic core. Toray MicroPly™ SC72A offers reduced processing, a one-shot cure, the ability to anchor inserts or fastenings, and increases the opportunity to consider lightweight, thin-walled composite sandwich structures. Considerable cost reductions can be realized when SC72A replaces prepreg as the core material, and where sandwich cores below 3 mm are difficult to achieve in honeycomb core, Toray MicroPly™ is a superior alternative. Toray MicroPly™ SC72A is available in a variety of thicknesses down to 1 mm and is easily contoured and shaped. SC72A is supplied on a roll (15 m x 400 mm) or in sheets (625 mm x 400 mm). Toray MicroPly™ SC72A is compatible for co-cure with Toray E720 and E722 mid temperature curing prepregs.
