We Solve Your Production Headaches
Anatomy of Quality
Multi-layer construction for extreme performance.
Why Silicone Adhesive?
Unlike acrylic, silicone maintains bond strength at 260°C and removes cleanly without leaving sticky residue.

Our Promise
We know your line cannot stop. That's why we treat every order as a long-term partnership, not a one-time sale.
We always start from samples and line test before any mass order.
Any confirmed quality issue from our side, we replace or refund according to agreement.
Direct access to our engineers for tape selection and process optimization.
From Master Roll to Finished Part
We handle coating, slitting and die-cutting under one roof so you don’t have to manage multiple suppliers.
Master Roll Production
Base film coating and curing with tight adhesive thickness control.
Coating capacity Up to 500 mm width · 2000 m length
Precision Slitting
Custom roll width for your line – no extra trimming at your side.
Slitting precision Down to 2 mm · ±0.05 mm tolerance
Rotary Die-Cutting
Custom shapes, discs and dots kiss-cut on liners for fast assembly.
Process readiness PPAP / EV / Medical friendly process
What Our Customers Say
Real feedback from engineers and purchasing teams using CT Tape in PCB, EV, 3D printing and more.
“We were constantly cleaning residue off gold fingers after reflow. After switching to CT Tape’s polyimide, the residue issue basically disappeared and our team stopped reworking boards.”
Operations Manager
Tier-1 EMS, USA
“CT Tape supported us from first samples to PPAP and mass production. Slitting tolerance and adhesion are very stable, which is critical for our automated battery line.”
Senior Process Engineer
EV Battery Plant, Germany
“We tested several suppliers. CT Tape was the only one that combined strong adhesion with clean removal on our printer beds, even after multiple heating cycles.”
Product Manager
3D Printer OEM, Japan
“We needed a supplier that could keep up with our schedule changes. CT Tape reacts fast on rush orders and keeps our harness lines running without material gaps.”
Supply Chain Supervisor
Automotive Harness Factory, Mexico
“Their engineering team helped us choose the right adhesive level for both EV and control boards. Samples arrived quickly and we moved to mass production without changing the tape.”
Head of Purchasing
Electronics Manufacturer, India
“We audit all suppliers carefully. CT Tape provided complete documentation and traceability. Their lab reports made our internal qualification much easier.”
Quality Manager
Precision Manufacturer, France
From Drawing to Mass Production
We keep the process simple so your team can move fast.
Share Your Requirements
Send us your drawings, current tape specs, or photos of your application. Our engineers will review and suggest tape structure & width.
Get Samples & Quote
We prepare free samples for line testing and send you a detailed quotation with lead time, packing and shipping options.
Confirm & Start Production
After your line approval, we lock specs into our system and start mass production. Each batch comes with COA and test reports.
