Material Highlight: Polyimide Films
What Are They?
Polyimide films are anything but ordinary. These films are engineered for long-term performance at extreme temperatures between -450°F to over 500°F over extended periods of time. So, obviously, thermal stability is a major benefit, which is why this film is so widely used in aerospace, electronics, and electrical industries when a high temperature material is required. Polyimide films possess a unique combination of properties that make it ideal for a variety of applications in a variety of different industries.
Features and benefits:
The ability of these films to maintain their tremendous physical, electrical, and mechanical properties over a wide temperature range immensely reduces the need for rework, helping to enable high productivity out of this product.
Dimensionally stable at high temperatures, which helps reduce rework, helping to enable high productivity.
Flame retardant, chemical and radiation resistant which helps protect surfaces to help reduce replacement costs.
