Electrical Insulating Fiberglass Tape, made of fiberglass yarn, has the characteristics of high temperature resistance, good insulation performance and strong corrosion resistance. It can be used for filling and binding insulation materials of transformers, motors, electrical appliances and cables.Its main component is aluminium borosilicate (E glass), and the content of alkali metal oxides such as potassium oxide and sodium oxide is less than 0.8%. Alkali-free glass fiber ribbon mainly includes ordinary type, reinforced type, reinforced bulging yarn type and so on. The difference between ordinary type and reinforced type is mainly due to the different sizing agents used in drawing fiberglass precursors, which determines the important differences in the use of products. Strengthened expanded yarn is made of glass fibers which are extruded and then knitted into ribbons.

Product Characteristics:
  • Excellent heat resistance, the maximum temperature is 600 Degree C
  • Light weight, heat resistance, small heat capacity & low thermal Soft and good thermal insulation.
  • Fiberglass tape does not absorb water, corrode, mildew,moth, scatter easily, and has certain tensile.
  • Excellent ageing resistance.
  • Good sound absorption, higher than the average requirement of NRC.
  • It can be tailored, sewed and constructed easily according to the requirements.
  • Glass fiber has good electrical insulation
  • Glass fibers are inorganic fibers and never burn.
  • Glass fibers have high tensile strength and length stability

Purpose:
  • Used for various heat sources (coal, electricity, oil, gas) high temperature equipment, central air-conditioning pipeline insulation; electric heating bracket, heating element
  • Used for all kinds of insulation and fire- proof materials,
  • high-temperature boilers, ovens, warm air heating equipment.
  • Sealing, sound absorption, filtering and insulation materials for special places;
  • Insulation for various heat transfer and storage devices
  • Sound insulation, heat insulation and heat insulation for vehicles,
  • ships, aircraft, etc..Insulation of the inner core of mufflers for
  • automobiles and motorcycles and mufflation of engines.
  • Inter layer thermal insulation of color steel plate and wood structure buildings.
  • Thermal and chemical pipeline insulation, thermal insulation effect is better than general insulation material
  • Heat insulation of wall panels of household appliances such as air conditioners, refrigerators, microwave ovens
  • Other occasions requiring heat preservation, insulation, fire prevention, sound absorption and insulation

Other Details:
  • Fiberglass insulation tape is made of nonalkali glassfiber yarn.
  • It is woven by twisted strands of fiberglass at right angles to one another, having the highest glass-resin ratio and mechnical strength of all fiberglass insulaiton materials.

Tape Width:
  • 1/2 inch, 3/4 inch, 1 inch, 1.5 inch, 2 inch

Dupont Nomex Insulation Paper is a calendered insulation paper which offers high inherent dielectric strength, mechanical toughness, flexibility, and resilience. Also available in variety, for an oil filled transform.


DuPontTM Nomex® 410, the original form of Nomex® brand paper, is widely used in a majority of electrical equipment applications. That's because the properties of Nomex® 410 make it an ideal choice for virtually every known electrical sheet insulation application.

The excellent properties of Nomex® 410, which include high inherent dielectric strength, mechanical toughness, thermal stability, flexibility and resilience, is a standard by which all other insulating materials are compared.

Nomex® 410 is available in 11 thicknesses, ranging from 0.05 mm to 0.76 mm

(2 mil to 30 mil), with specific gravities ranging from 0.72 g/cm2 to 1.1 g/cm2. As is true for all electrical insulating materials, thickness and density have an effect on the typical electrical, mechanical and thermal properties of Nomex® 410. Therefore, tables shown here of the typical properties of Nomex® 410 provide values for each available thickness and corresponding density.

Advantages:
  • Mechanical toughness and (in the grade) flexibility
  • Inherent Di-Electric Strength
  • Unaffected by most solvents, acids
  • Compatible with varnishes, adhesives & transformer fluids

Thickness:
  • 5 mil / 7 mil / 10 mil / 15 mil / 20 mil (0.25-2 mm)

Manufacturers presently produce medium or high density fiber glass insulation material that have slightly higher R values than the standard batts. It has been found that insulation material is a combination of two types of glasses that are fused together. When the two glasses cool down during manufacturing, the random curls are formed from that material. You will find that this material is less irritating and safe to work with. This is because there is no chemical binder used to hold the batts together. This fiberglass insulation material is available in a perforated plastic sleeves to help in handling material.
