DuPont™ Pyralux® FR products are acrylic-based flame retardant copper clad laminates, coverlays, bonpdplys and sheet adhesives for products requiring UL rating.
Features:
High bond strength
High thermal resistance
No refrigeration required for storage
Two-year product performance warranty
Able to withstand multiple lamination cycles without degradation
UL 94 VTM-0 flammability rating
UL maximum operating temperature (MOT) 105C
Pyralux® FR Coverlay and Bondply
DuPont™ Pyralux® FR coverlay (bondply) composites are constructed of DuPont™ Kapton® polyimide film, coated on one side (both sides) with a proprietary B-staged acrylic adhesive. They are used to encapsulate etched details in flexible and rigid-flex multilayer constructions.
Construction and Certification for Coverlay and Bondply:
Polyimide thickness: 12, 25, 50, 75 and 125um
Adhesive thickness: 12, 25, 50 and 75um
Certified to IPC 4203A/1
Pyralux® FR Sheet Adhesive
DuPont™ Pyralux® FR sheet adhesive is a proprietary B-staged modified acrylic adhesive coated on release paper. Sheet adhesive is used primarily to bond flexible innerlayers or rigid cap layers in multilayer lamination. It is also widely used to bond flexible circuits to rigid boards during the fabrication of rigid-flex circuits, as well as to bond stiffeners and heat sinks.
Construction and Certification for Sheet Adhesive:
Adhesive thickness: 12, 25, 50, 75 and 100um
Certified to IPC 4203A/18
