In high-precision manufacturing, not all tapes are created equal.
PET high temperature tape stands out thanks to its engineered structure — a combination of materials designed to resist heat, chemicals, and mechanical stress.
But what exactly is in this tape, and how does each layer contribute to performance?
Let’s break it down.

🔍 What Are the Key Structural Layers of PET High Temp Tape?
1. PET Film Backing (Polyethylene Terephthalate)
• 🟢 High tensile strength
• 🟢 Excellent dimensional stability
• 🟢 Smooth surface for clean masking lines
• 🟢 Heat resistance up to 230°C
• 🟢 Available in green, blue, or transparent
2. Silicone Adhesive Layer
• 🔵 High bonding strength on metal, plastic, and glass
• 🔵 Residue-free removal even after heat exposure
• 🔵 Chemically stable — won't react with coatings or solder
Optional: Anti-static coating, liner backing, or UV-resistant treatments for niche applications.

🏗️ How Does This Structure Help in Complex Processes?
| Process Type | Structural Benefit |
|---|
| Powder coating | PET film resists shrinking or tearing at high temp |
| PCB soldering | Silicone adhesive doesn’t leave residue on circuits |
| Laser cutting/masking | Maintains edge stability, no curl or shrink |
| Lithium battery wrapping | Ensures insulation and mechanical hold |
The result? Fewer failures, better product appearance, and lower production waste.

🧯 Is PET Tape Also Chemically Resistant?
Yes — the combination of PET and silicone adhesive makes the tape:
• 🧪 Resistant to solvents, acids, and alkalis
• 🔬 Ideal for masking in chemical etching or anodizing
• 🧼 Easy to clean off after processing
This versatility reduces the need for different masking materials across process lines.

🧩 Why Is PET Tape Better Than Polyimide or Paper Masking Tape?
| Feature | PET Tape | Paper Tape / PI Tape |
|---|
| Heat resistance | Up to 230°C | Paper <150°C; PI ~260°C |
| Adhesive residue | No | Sometimes (esp. paper) |
| Price | Moderate | PI is expensive |
| Die-cut capability | Excellent | Limited (paper tears) |
| Appearance (for end-user) | Clean and smooth finish | May stain or mark |
While polyimide excels in ultra-high-temp settings, PET strikes the best balance for general high-heat use at a lower cost.
