Preguntas frecuentes sobre los calentadores flexibles
¿Cuál es la diferencia entre un calentador de silicona y un calentador de PI (poliimida)?
Los calentadores de silicona son más duraderos, flexibles y adecuados para aplicaciones en exteriores o entornos exigentes. Los calentadores de PI utilizan una película fina de poliimida y son ideales para aplicaciones compactas que requieren ligereza y un control preciso de calentamiento.
En general, los calentadores de silicona ofrecen una mayor resistencia mecánica, mientras que los calentadores de PI permiten un mejor control del espesor y una respuesta más rápida.
