50u Red Polyester Tape High Temp
50u Red Polyester Tape High Temp
Industrial High Temperature Red Polyester (PET) Tape
High-visibility crimson PET carrier with silicone pressure-sensitive adhesive. Engineered for rapid visual inspection in powder coating, electrocoating, and silicone release liner splicing.
🔴 High Visual Contrast
The bright crimson red backing makes alignment checking effortless on dark metal substrates, automated optical inspection (AOI) lines, and complex die-cuts.
🔥 220°C Thermal Peak
Formulated to withstand bake oven cycles up to 220°C (428°F) for 30 minutes without shrinking, lifting edges, or thermal breakdown.
🛡️ Zero Residue Guarantee
Special cross-linked silicone adhesive peels off cleanly in one piece after thermal processing, eliminating costly manual cleanup or solvent wiping.

💬 Direct WhatsApp Consultation (+86 13798812128)Q: Why choose Red High Temp Polyester Tape instead of Green PET tape?
A: While both green and red PET tapes offer similar temperature resistance up to 220°C, red tape provides significantly higher contrast against silver, aluminum, and stainless steel surfaces. This makes it easier for operators to inspect masked areas and ensures no tape is left behind after curing.
Q: Is this red polyester tape effective for splicing silicone-coated materials?
A: Yes. The specialized silicone pressure-sensitive adhesive bonds exceptionally well to siliconised release papers and poly-coated liners, making it an industry standard for high-speed web splicing.
Q: Can you supply custom slitting widths and jumbo roll formats?
A: Yes. Master jumbo rolls (980mm width × 66m or 500m length) can be slit down to any custom width starting from 3mm with a precision slitting tolerance of ±0.2mm.
Q: Does the red color bleed or stain surfaces during high-temperature baking?
A: No. The red pigment is integrated into the polyester carrier film layer itself rather than the adhesive. It will not bleed, transfer, or stain coated metals or electronic components during 220°C oven cycles.
