Widely employed in UPS power supplies, dry-type transformers, high-frequency transformers, and microwave oven transformers. It serves as a barrier to prevent current from creeping along the edges of windings and gaps between windings and the core under high voltage, ensuring copper wire insulation remains intact.
Used for winding, anchoring, and insulating the coils of series-excited motors and capacitors, delivering high-temperature resistance, voltage breakdown protection, and superior puncture resistance.
Often integrated with Teflon sleeves, Mylar tape, and outer wrapping components to systematically enhance dielectric properties and improve overall insulation system reliability.
Suitable for high-temperature power frequency transformers, insulation gaskets in thermal operational settings, and various industrial applications demanding strict heat resistance and flame retardancy.
The tape consists of a non-woven fabric bonded to a polyester (PET) film substrate, coated on one side with either high-performance acrylic adhesive or rubber-based adhesive.
It features a standard continuous temperature resistance of up to 130℃ and provides high voltage breakdown resistance starting from 5.0kV up to 14kV depending on the thickness layer.
The rubber adhesive series serves as direct functional equivalents: HY300-1 matches 3M 44, HY300-2 matches 3M 44D-A, and HY300-3 corresponds to 3M 44T-A.
The tape is available in Beige (Rubber adhesive series, 0.14mm to 0.42mm) and White (Acrylic adhesive series, 0.15mm to 0.42mm / 15G to 85G), offering 1-layer, 2-layer, and 3-layer builds.
It creates a physical and dielectric retaining wall barrier along the coil edges and gaps between winding sections and the core, halting electrical creepage under elevated voltage conditions.
Yes, it is routinely used in conjunction with Teflon sleeving, Mylar insulation tape, and thermal barriers to maximize mechanical strength and system insulation integrity.
