Polyonics has introduced a new flame retardant battery tape for bonding applications. XT-657 flame retardant bonding tape is designed to help prevent the propagation of fire, provides dielectric separation between electrical circuits and eliminates mechanical fasteners in battery assemblies and packs. The halogen-free UL94 VTM-0 tested tape provides a thin, conformal bond line and offers an adhesive strength of greater than 32 oz/in (> 35N/100 mm). The tape has been proven effective in bonding Li-ion batteries used in today’s space-constrained consumer electronics devices as well in industrial power and battery applications. XT-657 is a high temperature bonding system that is used to attach batteries and components to chassis, boards, other batteries, etc. The REACH and RoHS compliant tape includes a 1 mil (25 µm) polyimide film, two layers of 1 mil acrylic pressure sensitive adhesive (PSA) and a variety of liners that aid in handling, diecutting and auto application.
