High-insulation TUFFY adhesive is a specialised variant of the TUFFY adhesive range, developed to enhance electrical insulation properties whilst retaining the high toughness and impact resistance characteristic of the TUFFY family. It is designed to provide reliable structural bonding and stress absorption whilst simultaneously creating a high-impedance, breakdown-resistant electrical barrier to prevent electrical leakage and signal interference.
Its core characteristics lie in combining excellent toughness with extremely high insulation reliability. Not only does it possess the high peel strength and resistance to impact from drops inherent to the TUFFY series, but, more importantly, it boasts extremely high volume resistivity and dielectric strength, enabling it to maintain insulation stability over the long term in harsh environments such as those with high humidity and high temperatures. Furthermore, its low dielectric constant and low dielectric loss ensure minimal interference with high-frequency signal transmission, whilst it maintains strong adhesion to a wide range of substrates, making it resistant to delamination and failure.
✅ New Energy Power Batteries: The adhesive bonding of the insulation structure between the battery cells, busbars and flexible printed circuit boards within the battery module prevents creepage and absorbs vibration stresses.
✅ High-end consumer electronics: Insulation, secure mounting and earthing protection for RF antennas, camera modules, connectors and metal components in mobile phones and tablets, having passed rigorous whole-unit drop tests.
✅ Semiconductors and Chip Packaging: Localised stress relief and insulation protection in chip packaging, as well as underfill, are particularly well-suited to advanced packaging applications requiring both impact resistance and insulation.
✅ Electric Vehicle Charging Systems: Insulated mounting of live components—such as the on-board charger (OBC), copper busbars and terminals within the high-voltage distribution box—to the heat sink base.
✅ Motors and Generators: Insulation and vibration damping for the magnets and windings inside the motor, to prevent inter-turn short circuits caused by vibration-induced wear.
✅ High-voltage electrical equipment: The structural bonding and insulation sealing of components such as transformer cores, insulators and current transformers must withstand the rigours of long-term exposure to high and low temperatures outdoors.
