Battery Bonding Tape

Double coated tape
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.

Typical Battery packbattery tape 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.

Design Requirements

Today’s batteries provide high energy and capacity, but at the risk of low thermal run-away temperatures (<150C). A thermal run-away results from many causes that can produce flammable gases and lead to fire and/or explosion.

Thermal management is the key to optimal battery performance. High temperature, flame retardant tapes offer a proven, economical method to provide this management by insulating batteries from adjacent components and/or additional batteries and reducing the risk of fire.

Polyonics Introduces Engineered Tapes and Label Materials That Protect Static Sensitive Optoelectronic Devices from Harmful ESD Events
Polyonics makes antistatic tapes and label materials with static dissipative surface resistances and low tribocharging pressure sensitive adhesives (PSA) that allow them to protect static sensitive optoelectronic devices such as LEDs, photo and laser diodes, solar cells, etc. and help prevent harmful electrostatic discharge (ESD) events.

Polyonics Announces Expanded Antistatic Tape Product Line:
New Materials, Thinner Constructions, New Coatings and New PSAs Polyonics has recently expanded its antistatic tape and film portfolio to include a wider variety of single and double coated amber and black polyimide and clear and white polyester (PET) constructions. New thinner 40 µm (1.6 mil) antistatic tapes and 13 µm (0.5 mil) antistatic films have also been added for space constrained applications with specially developed matte black coatings available to match specific color and gloss specifications.

Polyonics Introduces High Temperature Bonding Systems for Static Sensitive Devices
Westmoreland, NH (PRWEB) —Polyonics has introduced a series of double-coated tapes that are designed to protect SSD (static sensitive devices). The tapes are well suited for SMT (surface mount technology) applications and provide a strong, thin conformal bond line while generating a very low peel voltage.
