Double coated halogen free UL94 VTM0 flame retardant tapes used to bond Li-ion batteries to PCBs.
Double coated FR Tape Construction.
Along with flame retardant battery protection tapes, Polyonics also manufactures a variety of double coated flame retardant tapes that insulate and bond batteries and associated components plus help prevent the propagation of fire. The tapes offer exceptional dimensional stability to help continue to insulate components at extreme temperatures.
The halogen free, REACH and RoHS compliant tapes help insulate components from external heat sources while providing a thin conformal bond line (<50µm) for bonding batteries and associated components to chassis, boards, etc. Using FlameGard technology, the Polyonics battery tapes form a char layer to help prevent the propagation of fire.
The tapes include high strength and high temperature halogen free adhesives (PSAs) to allow bonding to a variety of surfaces and to tight radii. Tape construction options allow the PSAs to be different on the two sides of the tape to optimize bonding to dissimilar surfaces.

Custom double coated constructions are also available to best match each application.
Typical battery pack and EV battery applications using double-coated bonding tapes eliminate mechanical fasteners.
Die cut liners
The battery bonding tapes have liners that allow die cutting and auto application. This feature increases the precision of the bond, reduces waste and improves manufacturing and assembly efficiencies. The liners are selected to optimize each die cut process.
Polyonics battery tapes are tested for compliance to some of the most stringent industry flammability, smoke and toxicity standards including UL94 VTM0, FAR 25.853 and BSS 7238.7239.
- SCK: Super Calendered Kraft liner.
- PET: Polyester or Fluorinated Polyester (silicone PSA) liners.
- MOQ: 9” x 1640’ (for
single coated tapes)
and 9” x 1000’ (for aluminum and double-coated, silicone and LSE PSA tapes)
- All tapes are REACH and RoHS compliant
- Flame retardant tapes are not recognized by UL but have been tested to the UL94 standard by Polyonics.
- The surface on which the tape is to be applied whould be clean, dry and free of any surface contaminations, such as dust, oil or rust, isopropyl alcohol would be a recommended solvent to clean the surface.
