When your projects demand insulation that won’t quit under thermal stress, NBRAM’s Silicone Resin Bonded Mica Tape steps up. We’ve engineered this tape to hug complex geometries while handling temperatures soaring to 1000°C. It’s the kind of reliability that keeps motors humming in steel mills and transformers secure in renewable energy setups. If you’re sourcing high-performance insulation, this tape brings together compliance with international standards and NBRAM’s rigorous quality—making it a smart pick for engineers who value durability and safety.
Let’s talk about what makes NBRAM’s Silicone Resin Bonded Mica Tape a workhorse in heavy-duty electrical insulation. Built to perform in environments where heat and electrical stress are part of daily operation, this tape is a top choice for insulating motor windings, transformer coils, and high-voltage cables. The magic lies in how we bond layers of high-grade mica with a flexible yet tough silicone resin—this duo teams up to resist cracking, tracking, and degradation over time. It’s trusted by folks in power gen, marine engineering, and heavy industries because it simply doesn’t let them down.
Here’s where this tape really shines: it wraps snugly around odd shapes and tight spaces without losing its insulating chops. That’s thanks to the silicone resin’s give and the mica’s natural resilience. You’ll see it lining fire-resistant cables that have to keep working in emergencies, or insulating heating elements that cycle between hot and cold. It’s also a go-to in corrosive settings—think chemical processing or offshore rigs—where moisture and acids are constantly testing materials. With NBRAM’s tape, you get fewer failures and less downtime, which keeps projects on track and maintenance teams happy.
NBRAM delivers this Silicone Resin Bonded Mica Tape in thicknesses from 0.08mm to 0.15mm—handy for everything from fine motor work to big transformer jobs. Widths? We cover from 10mm all the way to 1000mm. It’s rated for dielectric strength of 6–8 kV/mm and doesn’t flinch between -50°C and 1000°C. We back it with glass fiber or polyester reinforcement for extra tear resistance. Oh, and it plays by the rules: IEC 60371 and ASTM D352 are covered. Need a custom width or adhesion level? Just ask—we tweak to fit your specs.
So how do we make tape that stands up to real-world punishment? It starts with picking mica that’s pure and flawlessly layered—because impurities undermine performance. We split it into thin consistent flakes that maximize surface area for better resin bonding. Then comes our silicone resin mix: we’ve tweaked the formula to stay supple after curing, so the tape won’t turn brittle when the heat is on.
The real artistry is in coating. We saturate either fiberglass mesh or polyester film with the mica-resin blend using a controlled knife-over-roll process. This ensures every inch gets even coverage without weak spots. Curing happens in ovens where we gently ramp up heat to avoid bubbles or distortion—it’s a bit like baking a perfect soufflé, minus the eggs.
After curing, we slit the tapes to size and wind them with care to avoid edge damage. But we don’t stop there: every batch gets put through its paces. We test dielectric strength, flex it repeatedly to mimic installation stress, and cycle it between extreme temperatures to simulate years of service in a few days.
Why does this matter? Because in applications like wind turbines or EV traction motors, insulation failure isn’t an option. Our tape stays put through vibration and thermal expansion, thanks to that tailored resin elasticity. We also get questions about varnish compatibility—rest assured, it works seamlessly with common industrial varnishes, so integrating it into your process is straightforward.
