Description
Fiberglass insulation tape is woven glass-fiber tape used for winding insulation, wrapping and binding in electrical equipment. For ordering, specify whether plain or treated tape is required, together with thickness, width, roll length and the intended motor or transformer application.
Electrical, thermal and flame-performance requirements should be checked for the supplied tape construction, including any binder or coating. Confirm the exact grade and approved application; a glass-fiber base alone does not establish the rating of the finished tape or the complete insulation system.
Fiberglass insulation tape is widely used where high temperature stability and electrical safety are required, especially in electrical insulation systems exposed to continuous heat and mechanical stress.
Chengrui insulation can offer plain white fiberglass tape, fiberglass tape with lines in the middle, fiberglass tape with resin etc.

Why Fiberglass Tape Is Used for Insulation
Fiberglass tape is widely selected for insulation because it combines thermal stability and electrical insulation performance in a single material.
Key insulation benefits include:
Excellent thermal insulation at high operating temperatures
Reliable electrical insulation for coils, windings, and cables
Fire resistance, suitable for safety-critical applications
Mechanical reinforcement, preventing insulation layer damage
Long service life under continuous thermal stress

Types of Insulation Fiberglass Tape:
1. Plain Fiberglass Tape: Without coating. Main application: Coil insulation, high-temp electrical insulation
2. Acrylic Coated Fiberglass Tape: With acrylic resin. Main application: Motor winding insulation, electrical binding
3. Silicone Coated Fiberglass Tape: With silicone resin. Main application: High-temperature electrical insulation
4. PTFE Coated Fiberglass Tape: With PTFE(teflon).Main application: Harsh chemical & high-temp environments
Fiberglass Insulation Tape Applications
It is used for binding, intern, winding of electrical motor. It can be also used as wrapping and banding material for transformers, electric motors, and cables.
How to Choose the Right Insulation Fiberglass Tape
When selecting insulation fiberglass tape, consider the following factors:
Operating temperature of the application
Electrical insulation requirements
Mechanical stress and abrasion conditions
Environmental exposure (chemicals, moisture, oils)
Need for coated or uncoated tape
Plain fiberglass tape is suitable for general insulation, while coated fiberglass tapes are recommended for applications requiring enhanced durability or environmental resistance.

Quick Answers for You
Quick answers to your pressing questions.
Q: What thickness, width, length, and tolerance can you supply?
A: Chengrui Insulation can supply standard sizes and also customize dimensions according to customer drawings or application requirements. The tolerance depends on material type, thickness, and processing method. Before quotation, customers should confirm thickness, width, length, quantity, roll weight, or drawing dimensions.
Q: Can you process according to drawings, such as strips, punching, CNC machining, molded parts, and oil duct spacers?
A: Chengrui Insulation can provide custom processing according to drawings, not only raw insulation materials. Common processing includes strip cutting, punching, chamfering, slotting, CNC machining, and components etc.
Q: Is this material suitable for my transformer type, oil-immersed or dry-type?
A: Chengrui Insulation can offer insulation materials both for oil-immersed transformers and dry-type transformers. Common materials for oil-immersed transformers include electrical kraft paper, diamond dotted paper, crepe paper, insulation pressboard, pressboard strips, oil duct spacers, insulation cylinders, and laminated wood. They are widely used for winding insulation, interlayer insulation, end insulation, oil ducts, and support structures. For dry-type transformers requiring higher thermal performance, we normally recommend NMN, NHN, AMA, polyimide film, epoxy fiberglass sheets, etc
Q: Are you a trader or manufacturer?
A: Chengrui combines our own manufacturing capabilities (flexible laminates, insulation sleeving etc) with a qualified partner production network. This allows us to supply a broader range of electrical insulation materials while maintaining specification control, quality inspection and technical support.
Q: What technical documents can you provide?
A: Depending on the material, we can provide ISO, TDS, RoHS, REACH, SGS reports and relevant IEC or UL information for technical evaluation and supplier approval.
