Withstands up to 500 °F (260 °C) — glass fibre & PTFE-coated grades.
For genuine high heat, cloth tape means woven glass fibre (glass cloth) or PTFE-coated fibreglass. Glass cloth tape handles 180–200 °C+; PTFE-coated fibreglass adds non-stick and chemical resistance for heat-sealing machines.
Yijiayi states real physical limits — e.g. withstands up to 500 °F (260 °C) — in both Celsius and Fahrenheit for North-American buyers.

Your wiring runs through the engine compartment where it faces high heat and constant rubbing, and ordinary tape melts or wears through.
Read the guideYou are building an electric-vehicle high-voltage system and need the orange safety-coloured, heat-resistant, flame-retardant wrap for battery and motor harnesses.
Read the guideYou need to insulate windings, hold coils and provide layer-to-layer dielectric protection in a transformer, motor or battery.
Read the guideYour heat-sealing or shrink-wrap machine needs a non-stick, high-temperature tape on the sealing bar so nothing sticks and it survives repeated heat.

Standards: PTFE/silicone construction rated to 260 °C; typical consumption 2–10 rolls/month per sealing machine.
High-temperature glass cloth and PTFE-coated fiberglass tape withstands up to 500°F (260°C). ONEI supplies both grades.
PTFE-coated fiberglass tape (heat + release + chemical resistant) is standard on heat-sealing machines. ONEI manufactures it.
Yes — ONEI coats fiberglass and PTFE tapes in-house, controlling the silicone / PTFE coating so the 260 °C (500 °F) rating and release behaviour stay consistent across large orders.
ONEI offers plain glass cloth, silicone-adhesive glass cloth and PTFE-coated fiberglass in a range of thicknesses — choice depends on whether you need insulation, release or chemical resistance. Send the application and we'll confirm the grade.
Yes — ONEI slits to custom widths and die-cuts glass-cloth / PTFE tape to spec for heat-sealing bars, platens and insulation parts.
Glass cloth handles 180–200 °C+; PTFE-coated fibreglass with silicone adhesive is rated to about 260 °C (500 °F).
Its non-stick, heat- and chemical-resistant surface makes it ideal for heat-sealing bars and packaging machinery where nothing should stick.
Yes — we label temperature limits in both °C and °F for North-American customers.
