For electronic circuit boards, soldering, protecting and upscale electrical insulation, motor insulation, as well as lithium battery positive and negative protection. Polyonics polyimide tapes are dimensionally stable at high temperatures so they remaining intact during the numerous temperature cycles batteries experience. The tapes also insulate the batteries from external high temperature heat sources within the device. In addition, the halogen free (including bromine and chlorine free), flame retardant tapes prevent the propagation of fire. Polyonics tapes include both single coated tapes for masking and double coated tapes for bonding and are REACH and RoHS compliant. A lithium-ion battery or Li-ion battery (abbreviated as LIB) is a type of rechargeable battery in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging. Li-ion batteries use an intercalated lithium compound as one electrode material, compared to the metallic lithium used in a non-rechargeable lithium battery. The electrolyte, which allows for ionic movement, and the two electrodes are the constituent components of a lithium-ion battery cell. Lithium-ion batteries are common in home electronics. They are one of the most popular types of rechargeable batteries for portable electronics, with a high energy density, tiny memory effect and low self-discharge. LIBs are also growing in popularity for military, battery electric vehicle and aerospace applications. 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.
