Pro® 730 Fiberglass Cloth Tape for Building & Construction

Our Pro® 730 Glass Cloth tape is a 7.0 mils woven fiberglass cloth tape with a rubber based thermosetting adhesive. It is designed for high temperature applications.

About Pro® 730 Glass Cloth Tape:

The thermosetting feature of Pro® 730 Glass Cloth tape creates a dependable bond where high heat temperature occurs; once it reaches a certain temperature, the bond strength is achieved.  This tape can withstand continuous temperature up to 260°F / 130°C (depending on the type and duration of the heat source.)

Our Pro® 730 Glass Cloth is flexible and conforms to uneven surfaces and irregular shapes. The backing will not shrink, rot or burn and offers abrasion protection/puncture resistance. 

Pro® 730 is designed to operate in 2,000 volts dielectric strength (Max.) dry applications requiring high tensile strength, strong holding power.  The scientifically designed non-corrosive rubber adhesive system resists degradation and provides corrosion free protection from chemicals and other contaminants.

Pro 730 Glass Cloth Tape is widely used for transformers, electrical coils, heat furnaces and similar applications

Uses & Applications for Pro® 730

Our Pro® 730 Glass Cloth tape is widely used in the transformers, electrical coils, heat furnace and similar markets. It is an ideal solution for electrical maintenance such as:

  • Coil Wrap in capacitors, transformers and motors.
  • Crossover insulation and coil banding.
  • Electrical insulation


The glass cloth market is expanding at a rapid pace to other market segments such as Renewable Energy, Transportation, Marine, Construction, Aerospace and Defense, due to the increasing use of glass cloth tapes as electrical insulators in the manufacturing sector. 

The cost effectiveness of glass cloth or fiberglass cloth tape plays a major role to the market growth when compared to alternate products within the industry.
