This mica tape uses high-quality resin-glued phlogopite mica paper reinforced with alkali-free glass fibre cloth. The glueing process forms a uniform adhesive resin layer on the cloth surface, which is then covered and protected with release paper. Mica tape can be used as a high-temperature-resistant insulating material in construction, aerospace, electronics, and related fields.
Mica tape with PSA can be used to wrap copper and aluminiumm busbar connectors, anit provides aes as ti fitghte fitr, especially at 3D bends. The winding performance is tighter than that of glue-free mica tape. Mica tape with PSA can also be reprocessed and glued to other materials to obtain superior properties.
The standard thickness of specially designed mica tape with an adhesive layer is 0.1mm, 0.12mm, 0.15mm, 0.2mm, or 0.3mm, or as customised.
Application
Mica tape with PSA has excellent electrical and thermal insulation and is fireproof. When combined with a glass fibre cloth, it has considerable tensile strength. The mica tape can be covered and wrapped consistently and efficiently with a single layer. The most common usage is as follows:
1. Fireproof insulation layer for power batteries. Remove the release paper on the PSA mica tape, then cover and stick it on the battery module to achieve electrical insulation, fireproof, and flame-retardant effects.
2. Shield isolating mica tape. With the stick layer, we can wrap mica tape around EV copper bars, extruded busbars, and aluminium busbar connectors to ensure a good fit. Processing consistency, high efficiency, and stable tape overlap control. It’s incredibly fit for the 3D bars. The components have high dielectric strength with mica tape armour and resist high temperatures, high voltages, and flames.
3. Flash hider, barrier separating layer, and protector for EV. Mica is used to construct thermal barriers that prevent heat transfer between surfaces. Mica tape is fire-retardant and the primary material for the flash hider and the shield-isolating layer.
4. Combine with insulation material, such as Aramid fire shield and aluminium silicate insulation material, to achieve multiple flash hiders.
