It is used as a reinforcement material for high-voltage coil winding molds in transformer manufacturing. The product is made by fully curing glass fiber combined with epoxy resin, resulting in high structural integrity. With its high dielectric strength and low dielectric loss, it plays a vital role in the electrical industry. It also offers excellent mechanical and electrical properties, along with superior impact strength and crack resistance. 
H-grade insulation has a thermal resistance of up to 180°C. It generally offers higher dielectric strength and is well-suited for use in high-temperature environments. The base materials used are typically heat-resistant substances, making it ideal for equipment operating under elevated temperatures.
The material is available in customized widths upon request. It is engineered to minimize the release of harmful fiber dust and particles during processing, contributing to improved safety and working conditions in harsh manufacturing environments.
