HPPFILM MYLAR® POLYESTER FILM

MYLAR is made in a variety of different
Types, many in either roll or sheet form,
in a variety of guages and widths. Each
type is designed for a specific application.

TYPE A: is a strong, tough, dimensionally
stable film for general purpose applications
such as engineering reproduction materials,
stationery supplies, apparel stays and
industrial laminations with other flexible
materials. 		TYPE S: is a transparent film with a
brilliant surface designed for office
supplies, book jacket covers and sheet
protectors.

TYPE D: with even greater clarity and
brilliance than type S, is often used as
a substrate for microfilm, photographic
and graphic arts films.		 TYPE EL: is a general purpose electrical/
electronic grade polyester film which has an
excellent balance of physical properties. It is
Commonly used as the printed circuit base in
membrane switch applications.

Type EB-11: is a polyester film of low gloss
with matte properties going completely
through it. It is an exceptionally strong film
with high resistance to acids, mild bases and
solvents. Type EB-11 is used as a graphic
base in membrane switch and other
applications where a low gloss appearance
is required.
