Insulated fixing tape

Surface Cleaning:
Plasma treatment or solvent cleaning (to remove grease and dust).
Corona treatment (for plastic films):
Increases surface energy and enhances adhesive adhesion.
Primer Coating (optional):
For low-surface-energy materials such as PI film, improving adhesive bonding.

Coating Method:
Comma Blade Coating (High-Precision Control of Adhesive Layer Thickness).
Slit Coating (Suitable for High-Viscosity Adhesives, Solvent-Free).
Adhesive Layer Thickness:
Usually 10-50μm, with uniformity control required (±2μm tolerance).
Drying Process:
Step-by-step drying (e.g., 80°C → 120°C → 150°C) to avoid solvent residue and air bubbles.

Laminated Release Film:
Protecting the adhesive surface and preventing adhesion of the roll (release film must be heat-resistant).
Heat Curing:
Some adhesives require high-temperature curing (e.g., silicone gel curing at 150-180°C for 1-2 minutes).

Slitting:
Slitting into various widths (e.g., 5mm, 10mm, 20mm, etc.) according to customer requirements.
Die-Cutting (Optional):
Processing into specific shapes (e.g., insulating gaskets with positioning holes).

Surface Coating:
Spray-on ceramic coating (improves arc resistance, for high-voltage insulation).
Flame Retardant Treatment:
Impregnated with flame retardant (e.g., phosphate ester), meeting UL94 V0 standards.

Electrical Properties:
Insulation resistance (≥10^12Ω, 500VDC test).
Dielectric Strength (≥5kV/mm, no breakdown for 1 minute).
Mechanical Properties:
Tensile Strength (PI substrate ≥150MPa), Peel Strength (≥1.5N/cm).
Heat Resistance Test:
High-Temperature Aging (e.g., no delamination or embrittlement after 200°C/1000h).
Environmental Testing:
Humidity and Heat Cycling (85°C/85%RH), Thermal Shock (-40°C to 150°C).

Dust- and moisture-proof packaging: Vacuum aluminum foil bags or anti-static packaging. Marking: Indicates temperature resistance level, insulation voltage, flame retardant level, etc.
