Chemically Resistant adhesives

Rogers Corporation RO4450F Prepreg
Categories: Polymer; Thermoset

Material Notes: Prepreg is commonly used to inexpensively form less critical signal layers in antenna designs. A high post-cure Tg makes RO4400 series prepreg an excellent choice for multi-layers requiring sequential laminations as fully cured RO4400 prepregs are capable of handling multiple lamination cycle.

RO4450F™ prepreg has demonstrated improvement in lateral flow capability.
