What is the difference between the heating film and the use of silicone heating film or PI heating film, this is the question that many customers will have when consulting the heating film. In fact, the performance of the two is basically similar, mainly heating demand and use environment.
1, the first time from the appearance to distinguish, PI material is very thin, generally about 0.3-0.5mm; while silicone material is conventionally ± about 1.6mm.
2, Secondly, from the perspective of temperature resistance, silica gel imported materials can be more than 250 degrees temperature; PI is generally around 180 degrees.
3, finally from the heating material to distinguish, PI internal heating element is generally metal materials, such as brass, iron chromium aluminum, stainless steel etched; Silica gel can be metal heating wire, can also be metal material, from the heating element can be selected according to the demand. In addition, PI heating film is generally more suitable for small area products, while silica gel can be used in large area and exposed environments.
