Pyralux® FR coverlay
DuPont™ Pyralux® FR coverlay is a composite of DuPont™ Kapton® HN polyimide film, coated on one side with a proprietary, flame retardant B-staged modified acrylic adhesive. Coverlay can be used to encapsulate etched details in flexible and rigid-flex multilayer constructions for environmental protection and electrical insulation.
Pyralux® FR bondply
DuPont™ Pyralux® FR bondply is constructed of DuPont™ Kapton® HN polyimide film, coated on both sides with a proprietary, flame-retardant, B-staged modified acrylic adhesive. Bondply is used to encapsulate two etched details for environmental protection and electrical insulation.
Pyralux® FR sheet adhesive
DuPont™ Pyralux® FR sheet adhesive is a proprietary, flame-retardant, B-staged modified acrylic adhesive coated on release paper. Sheet adhesive is used primarily to bond flexible inner layers or rigid cap layers in multilayer circuits. It can also be used to bond flexible circuits to rigid boards during the fabrication of rigid-flex circuits, as well as to bond stiffeners and heat sinks.
