Fiberglass tape on spool

Our customized bobbin machine enables the joining together of longer lengths of material, and, in most cases the bobbin meterage can be as much as 10 times the linear metres normally contained on a pancake. With this fiberglass bobbin, our cable customers’ efficiencies can increase up to 300%, what’s more, waste reduces to as little as 1%.

It is a flexible tape which can be applied using all standard vertical or longitudinal taping machines.

Glass fiber yarn has high tensile strength, good electrical insulation, heat and chemical resistance.

Fiberglass insulating tape (alkali-free fiberglass tape) is woven from alkali-free glass fiber yarn, has good heat resistance and insulation, widely used in motor and transformer windings. The main ingredient is glass, sodium hydroxide, in which the alkali metal oxidation content does not exceed 0.5%.

The tape is overlaped by 50% when wraping, it provides the stability of the entire component. Secure wires, clamps, ties or pure silicone tape can be used to fix the place after the tape is installed.

It is suitable for the ribbon insulation of motor, pump and transformer, and is widely used in pipeline insulation, packing cable and switch box lining. With or without a self-adhesive bar.

Fiberglass tape is mainly used for fire-free cables that do not spread. In many cases, the electrical properties of the conductor’s insulation are such that they do not permit the use of non-flammable features, with insulating materials; Therefore, it is necessary to put an additional barrier sheath and insulating conductor and fiberglass band between the effective solution of this problem.

Natural fiberglass Band “E” denotes an effective aid when using the “Fire” cable – to ensure the continuity of performance in the case of fire – cases should use mica fiberglass tape or insulating materials in silicone rubber not enough to pass stringent test standards.


Fiberglass tape on spool is the advanced structure to make the cables and transformers wrapping more efficiently, it can be applied using all standard vertical or longitudinal taping equipment, with that, cables and transformers company can save many labor cost.

New Produt: 

Middle-alkali fiberglass tape is woven of middle-alkali fiberglass. With its feature of heat-resistance, the main component is glass, oxidation potassium, oxidation sodium, for which the content of oxidation of alkali metals is from 11.9%-16.4%.

Characteristics: This kind of fiberglass tape product has good thermal and fire resistance.

Application: Middle-alkali fiberglass tape can be used as wrapping and banding material for  cables (mainly for Chinese and some other Asia customers).
