FM® 6555-1

About
FM® 6555-1 is a cyanate ester syntactic core material. It was designed as a cost and weight saving alternative in the manufacture of thin, stiffness critical composite panels for low dielectric applications and satellite structures. FM 6555-1 syntactic core is based on CYCOM® 5575-2 glass and quartz cyanate ester prepregs, FM 2555 and FM 2525 structural film adhesives and FM 313-27C syntactic paste, providing a compatible family of products. FM 6555-1 is available in sheet or roll form (availability in roll form is dependent on product thickness). Suggested Applications: Thin composite panels for low dielectric applications and space structures where weight and/or cost are critical&&
