We usually say it is polyimide heaters. This is is very thin,the thickness is about 0.2mm,it is very light,so it is widely used on 3D printer the normal size for 3D printer are follow,

1,200*200mm,12v,200w

2,260*290mm,12v,145w

3,200*250mm,12v,90w and so on. any size,any shape can be customize. please contact with us.

Features of PI Film Heater

1. Light-weight, thin thickness offer faster warm-ups and quicker response.

2. Very flexible offer thermal contact with the Part for maximum heating efficiency.

3. Offered in a virtually unlimited range of shapes, sizes and wattage.

4. Their flat etched foil elements cover more area and transfer heat more efficiently than wire wound designs.

5. On request, temperature distribute in the surface of the heater.

6. Small thermal lag, precision temperature control and fast response.

7. Kapton insulation is stable, self-extinguishing, and highly resistant to oils, chemicals, fungus, solvents and radiation.

8. Thermostats and other sensors may be integrated into the design for accurate control and temperature tracing.

9. PSA is available as an option on heater rated at 1W/cm2 and 2W/cm2. The heater can be mechanically clamped or epoxy mounted by the user.

10. Very safety, realizable and long life.

Heating for very small sizes

Very thin

High dielectric strength

Flexible circuit design

Superior tensile strength and tear resistance

Resistant to radiation and most solvents

Better choice far high watt density heaters (those over 5 watts/in2). Also used for watt densities of 5 or less.

Excellent choice for heaters that require multi-zone wattage or heaters that have many holes and/or cutouts.

May provide an economic advantage for high volume applications.
