Aluminized Polyimide Sheets

Aluminum coated two sides polyimide sheldahl s family of polyimide films that are aluminized on both sides can be used as first surface mirrors and are often used in multi layer insulation mli blankets when a wide temperature range is desired.

Aluminized polyimide sheets. Use to quiet noisy areas and line machine enclosures. Thicker polyimide items are usually opaque. Mate ri als with low con duc tiv i ty sep a rate the alu minum lay ers. Sheets are made of polyimide foam.

In each of these a large measure of dupont kapton basic properties are combined with an extra attribute eg increased electrical or thermal conductivity improved corona resistance opacity and thermoplasticity. With lay ers of alu minum on one or both sides of the film to build reflec tor lay ers. Kapton polyimide film is used in a wide variety of applications such as substrates for flexible printed circuits transformer and capacitor insulation sensors and bar code labels. A range of dupont kapton film variants are also available.

Sheets are made of polyimide foam. All the lay ers form ing the mli blan kets aims to pro tect the sys tem. Sound absorbing sheets this insulation meets ul 94hf1 and astm e162 for flame retardance and astm e662 for smoke output. Dupont kapton polyimide films have set the industry standard for over 45 years in high performance reliability and durability with a unique combination of electrical thermal chemical and mechanical properties that withstand extreme temperature vibration and other demanding environments.

Caplinq linqstat pit1n alum series is a high performance high temperature resistant aluminized polyimide film formed by sputtering aluminum onto polyimide using an aluminum vacuum deposition method. Kapton film type hn kapton polyimide film from dupont has more than 50 years of proven performance as the flexible material of choice in applications involving very high 400 c 752 f or very low 269 c 452 f temperature extremes. Cirlex can operate routinely in a temperature range from cryogenic to a maximum of 400 c. Use to quiet noisy areas and line machine enclosures.

Cirlex polyimide technology has been developed by dupont to provide industry with a variety of thick polyimide sheets above the availability of kapton film. This combination of materials allows that one side is an insulation side and the other is conductive. Cirlex is an all polyimide adhesive less laminate.
