Dielectric High Silica Tape
Low-Moisture Dielectric High Silica Tape for Electrical & High-Temperature Insulation
Dielectric High Silica Tape is a high-performance insulation tape manufactured from high-purity silica fibers with silica content ≥96–98%, specially processed to achieve excellent dielectric strength, very low moisture absorption, and superior heat resistance.
This tape is designed for electrical insulation, thermal wrapping, RF-transparent insulation, and high-temperature sealing where reliability under heat and voltage stress is critical.
Key Performance Advantages
- High Silica Content: ≥96–98% SiO₂
- Excellent Dielectric Strength & Electrical Insulation
- Low Moisture Absorption (Dielectric Grade)
- Low Dielectric Constant & Low Dielectric Loss
- Continuous Service Temperature: Up to 1000°C
- Low Thermal Expansion (CTE)
- Flexible & Conformable for Easy Wrapping
- Non-Conductive & Non-Magnetic
- Non-Asbestos & Environmentally Safe
Dielectric high silica tape maintains stable electrical and insulation performance even under thermal cycling, humidity, and high-voltage conditions.
