High-Temperature Resistance of Surface Protection Tape

The high-temperature performance of surface protection tape depends on its material composition and adhesive properties. Most standard tapes withstand 60–80°C (140–176°F), while specialized variants endure up to 200°C (392°F) or higher. Key factors include:

1. Material Selection

• Polyethylene (PE) Tapes: Common for general use but soften at ~70°C (158°F).

• Polyimide (PI) Tapes: Excel in -269°C to +260°C (-452°F to +500°F) ranges, ideal for electronics and aerospace.

• Polyester (PET) Tapes: Resist up to 150°C (302°F), suitable for automotive coatings.

2. Adhesive Type

• Acrylic Adhesives: Stable up to 120–150°C (248–302°F); minimal residue upon removal.

• Silicone Adhesives: Withstand 200°C+ (392°F+) but may leave slight residue.

3. Applications

• Electronics: Reflow soldering (~250°C/482°F) demands polyimide tapes.

• Automotive: Engine bay parts require tapes resisting 150°C (302°F).

• Industrial: Powder coating processes use tapes tolerant to 180°C (356°F).

Testing Standards:

• UL 746B and ASTM D5476 evaluate thermal endurance.

Limitations:
Prolonged high heat may weaken adhesion or cause adhesive transfer. Always verify the tape’s datasheet for specific thermal ratings.
