**Introduction**
While "Adhesive PET material high temperature tape" offers flexibility and heat resistance, it requires timely replacement to prevent failures. Let’s identify key signs.
**Section 1: Adhesion Degradation**
- Tape peels easily from surfaces.
- Visible gaps between tape and substrate.
- Adhesive残留 left after removal—indicating weakened bonding.
**Section 2: Physical Damage**
- Cracks or tears in tape, compromising insulation.
- Significant discoloration (yellowing or darkening).
- Flexibility loss—tape becomes brittle or rigid.
**Section 3: Environmental Exposure**
- Prolonged exposure beyond 260°C.
- Chemical contamination (e.g., oil or solvent exposure).
- High-humidity environments leading to adhesive swelling.
**Section 4: Replacement Guidelines**
1. **Routine inspections**:每季度 check critical applications (e.g., motor windings).
2. **Time-based replacement**: For continuous use, replace every 1-2 years.
3. **Post-event evaluation**: After thermal cycling or solvent exposure, assess tape integrity.
**Section 5: Case Study: Automotive Wiring**
An auto company replaced PET tape every 18 months, avoiding 70% of insulation failures due to degradation.
**Section 6: Tips**
- Store spare tape in cool, dry conditions to extend shelf life.
- Use "PI material high temperature resistant 300 tape" for more severe environments.
- Avoid reusing tape for critical applications.
