Pen film, a multi-purpose new material for speakers, boasts various excellent qualities such as light weight and high rigidity relative to density. Applications of pen film: dome and balanced high-frequency drivers, ribbon and electrostatic flat speakers, and microphone components. Specifications: A slightly foggy transparent film with excellent processing properties.
PEN film boasts excellent long-term high-temperature aging resistance, capable of continuous use at 155℃ and meeting F-grade requirements. It maintains good dimensional stability under high temperatures, with low thermal shrinkage and effectively preserves its mechanical properties. It also exhibits a lower oligomer (Oligomer) extraction rate, and has superior glass transition temperature, hardness, hydrolysis resistance, and UV (UV) radiation resistance compared to PET.
PEN film finds extensive applications in the packaging industry. It is used for food packaging, electronic product packaging, household goods packaging, clothing packaging, and more. A common feature is that colored printing is required on the PEN film, and for food packaging, additional processes such as multi-layer lamination or vacuum aluminum coating are often necessary.
PEN Film Thickness: 6um, 16um, 19um, 25um, 38um (mm); Width: 1000mm; Excellent tensile properties, low gas permeability, and good barrier properties. The performance of PEN film is between polyester film and polyamide films.
PEN film is suitable for electrical insulation at temperature classes F and H, widely used in the electronics industry for labels, FPCs (Flexible Printed Circuits), MTS (Film Touch Switches), and speaker coils, as well as in packaging and general industrial applications. PEN film-made tapes are especially extensively used in automotive instrument panels and seat sensors, particularly in FPCs.
