Multiple Applications of Flexible Printed‑Circuit Heaters
Simply put, flexible printed‑circuit heaters are warming elements. They are manufactured to deliver heat for products, garments and other items. Precision screen printing is used to print conductive or resistive inks onto flexible substrates. The inks are typically composed of resistive and conductive materials, including functional carbon or silver. This enables diverse custom solutions for unique and specific application requirements.
Common printing substrates include polyester, polycarbonate, or polyimide — Kapton RS conductive film. They can also be printed on thermoplastic polyurethane (TPU). Thanks to the flexibility and elasticity of the material, TPU heaters are widely used in the apparel industry.
Basically, three main types of heating sheets are popular in today’s industry.
Flexible Printed‑circuit PET Heater
You may be familiar with the “old‑style” heating sheets commonly found in electric blankets. Conventional wire‑wound heating sheets feature fixed heat resistance and are still widely adopted in numerous products.
The drawbacks of wire‑wound heating sheets lie in bulky and sometimes inflexible wires, which may create uncomfortable contact points. Compared with PTC and Kapton RS heaters, wire‑wound heating sheets have limited application scope.
Kapton® RS Heater
Kapton® heaters are used for applications with demanding heating requirements. Nowadays, both PTC heaters and Kapton® RS heaters belong to the mainstream printed‑circuit heating elements. Naturally, Kapton® RS comes with several unique features.
Resistance Characteristics
Undoubtedly, both PTC heaters and Kapton® RS heaters come with their own advantages and drawbacks.
Shenzhen Fullchance Heating Products Factory has expertise in both technologies and can assist you in developing solutions tailored to your application requirements.
