Polyonics Introduces Ultra Thin High Dielectric Strength Double Coated (ESD)Tape

Latest company news about Polyonics Introduces Ultra Thin High Dielectric Strength Double Coated (ESD)Tape

Polyonics manufacturers a variety of double coated polyimide and polyester (PET) tapes with high strength acrylic and silicone pressure sensitive adhesives (PSA). These new tapes address the growing trend of replacing traditional mechanical fasteners with double coated tapes in permanent assemblies. The Polyonics double coated tapes provide ultra thin, conformal bond lines plus have the added value of dielectric strengths up to 7.7kV/mil to help insulate and protect electrical and electronic assemblies.


Polyonics double coated tapes have proven effective in bonding and attachment applications in virtually all industries where both high thermal and electrical insulation is required. The tapes include a variety of liners that allow them to be easily die cut into complex shapes and auto applied if necessary. In addition, their ultra thin constructions help engineers save space and weight in their complex assemblies.


Flame Retardant Options

The REACH and RoHS compliant tapes provide high temperature and chemical resistance. They are tear, puncture and abrasion resistant and have high tensile strengths and low elongation values. In addition, Polyonics double coated tapes provide halogen free flame retardant performance for applications where the prevention of the propagation of fire is required. These unique flame retardant tapes also include high dielectric strengths and are rigorously tested to the most stringent flame, smoke and toxicity standards including UL94, FAR 25.853 and BSS 7238/7239. The polyimide tapes are rated UL94 VTM0, the highest performance level.


All tape constructions are available with a variety of liners to best match each die cut process. They can also be configured with identical or dissimilar PSAs on each side of the tape to optimize the tapes adhesion to different surfaces. A low surface energy acrylic PSA is also available that provides strong adhesion to a wide range of plastic surfaces including polypropylene, polyethylene and TPO as well as powder coated surfaces.


Antistatic Options

Antistatic and static dissipative performances are also available with Polyonics double coated tapes. The tapes have surface resistances of 10^5 to 10^9 Ohms, the heart of the static dissipative range. They also generate very low peel voltages (less than 100v) when their liners are removed. This significant reduction in electrostatic charge helps simplify the die cutting process plus minimizes charges being transferred to static sensitive devices (SSD) during the mounting process. In addition, once in place, the antistatic tapes help dissipate unwanted electrostatic charges to further protect SSD from potentially harmful ESD events.


Polyonics tapes thermally insulate components and devices up to 570F (300C) with acrylic PSA constructions and up to 1000F (500C) with silicone PSA versions. Various PSA thicknesses are available to best suit the surface roughness and configuration of the bond.
