The high tensile strength and thermal endurance of glass fibers enables Hesgon to manufacture tapes in minimal thicknesses. This allows design engineers more flexibility and enables them to increase copper content and power ratings in electrical apparatus.
Whether operating in high ambient temperatures or developing high internal temperatures in electrical equipment, Hesgon glass tapes are virtually unaffected. The thermal endurance is limited only by the resins or varnishes combined with tape. The fiberglass tape does not start to soften until 732oC. The high thermal conductivity and rapid heat dispersion of glass tape is also very important in electrical equipment.
The high tensile strength of glass tapes prevent breakage under conditions that might normally weaken other insulating tapes. Pound for pound, fiberglass yarns are twice as strong as steel. Hesgon glass tapes retain 50% of their tensile strength at 340oC.
Hesgon tapes are manufactured of 100% fiberglass yarns with a minimum amount of sizing thus allowing for good wet-out impregnation. All tapes are also available in our standard or custom finishes to achieve maximum results with all the various resins available.
CT Finish & CT Yellow
This is a weave-setting finish wherein the warp and filling yarns are slightly fused together to stabilize the weave pattern and minimize the shifting of yarns. The tape retains its original white color with CT finish and has a light yellow color with the CT Yellow finish. This finish reinforces the tape and better enables it to withstand the abrasion frequently encountered in any winding operation. This tape, along with a gilt edge finish, is our best product for increasing operator comfort since it minimizes fiberglass dust and its associated mechanical irritation problems.
G10E Golden Finish
This is a weave-setting finish and constitutes a partial removal of yarn sizing. The tape is heated to a relatively low temperature and some of the oils and starch volatilize. The remaining starch is caramelized. This finish will improve the penetration of most varnishes due to the reduced binder content on the tape. The tape will cut cleanly without fraying and has a distinct golden tan coloration.
Gilt Edge Finish
A coating of synthetic resin is applied to the edges of the completed roll of tape with this treatment. This aids in better handling of the tape by the operator as it will not unroll without applying tension in a hand taping operation. The edges of the tape are reinforced to minimize fraying and unravelling when machine or hand taping.
In this heat cleaning process, the starch and oil binder is almost completely removed from the tape. This treatment is compatible with most all resins and the best adhesion or bond strength with silicone is achieved with this finish.
No 16 Finish
In this heat cleaning process the organic starch and oil binder is almost completely removed from the tape. A light coating of polyester and epoxy compatible silane finish is added to the tape for superior wet-out performance.
Golden Gilt Edge Finish
This double treatment combines our G10E Golden Finish with our Gilt Edge treatment to provide a tape that does not slip, unravel or fray during the taping operation. The treatment provides a good base and improved adhesion for subsequent varnish treatment, improves moisture barrier, and adds body for easier handling.
This finish, as well as our CT Yellow, G10E and Gilt Edge finishes, is compatible with 100% polyester, 100% pure epoxy, modified silicone, and standard general purpose clear baking varnishes.
