Flexible Heaters Part 3: PET (Polyester) – The Budget-Friendly Choice

If your project requires large-scale heating without the "premium" price tag of Polyimide, PET Heaters are the ultimate value-engineered solution.

Why choose PET?

• Cost-Efficient: The most affordable material for high-volume consumer products.
• Low Profile: Almost as thin as PI, but using a polyester substrate.
• Temperature Range: Best for low-to-mid temps, typically up to 100°C (212°F).
• Optically Clear: Can be made transparent, perfect for applications where visibility matters.

Best For:

• Consumer Goods: Heated insoles, pet warming pads, and blankets.
• Automotive: Side-mirror defoggers and seat heaters.
• Home Appliances: Mirror de-misters in bathrooms and small food warmers.

💡 Design Tip: PET is perfect for large-surface heating where extreme heat isn't required. At JLCPCB, we recommend PET for designs where keeping the BOM (Bill of Materials) low is the top priority.
