High-temperature and insulation tapes are the group most buyers come to us for. The range covers flame-retardant glass cloth tape rated to 300°C, 260°C polyimide tape for electronics, PTFE-coated fiberglass tape for heat sealing, white fiberglass cloth tape rated 0-300°C, and high-temperature PET and blue PET masking tapes.
Typical jobs: masking gold fingers and connectors through a reflow oven, insulating motors, transformers and heating elements, protecting surfaces during powder coating and baking, and running heat-sealing packaging lines.
Every tape in this group is produced at our 5000 m2 plant in Dongguan, Guangdong, China, with raw material identification and traceability plus finished product inspection before each shipment. Most items start at 100 rolls. Custom width, length, colour, printing and packaging are available for distributor and private-label programs, along with minor, drawing-based and sample-based OEM customization.
Frequently Asked Questions
What is the highest temperature your tapes withstand?
It depends on the material. Flame-retardant glass cloth tape is rated to 300°C and white fiberglass cloth tape is rated 0-300°C; polyimide tape is rated 260°C. Peak rating is not the whole answer, because the working temperature also depends on how long the tape stays hot, so confirm the continuous temperature and dwell time with our export team for your application.
Which tape should I use for PCB masking during reflow?
Polyimide tape is the usual choice for masking gold fingers and connectors through a reflow oven, because it holds at 260°C and releases cleanly. If your board runs hotter or needs a wider web, flame-retardant glass cloth tape covers the 300°C class.
Can you supply high-temperature tape in custom widths?
Yes. Custom width, length, colour, printing and packaging are supported, along with minor, drawing-based and sample-based OEM customization for distributor and private-label programs. Most items start at 100 rolls.
