ACLAR®-Fluoropolymer Films, Electron Microscopy Sciences

About this item

ACLAR® is made from fluorinated-chlorinated resins that provide an exceptional moisture barrier. ACLAR® is crystal clear, biochemically inert, highly resistant to most chemicals and sterilizable by heat or radiation. ACLAR® is used widely in pharmaceutical, medical, sensitive electronics and military packaging.

Crystal clear, high UV transparency- ideal for use in UV curing of embedding resin in microscopy
Chemically stable and biochemically inert- the product of choice for growing cell cultures
Low dielectric constant, high electric strength and dissipation factor– offers excellent cell attachment even through lengthy processing procedures
Low surface energy–and separates easily from epoxy
Exhibits no detectable autofluorescence– ideal for fluorescent microscopy
A non-flammable, non-aging co-polymer– which is suited for sterilization by heat or UV
Crystalline melting point is 206 °C (403 °F)– stable in the SEM
Flexible and soft– can be sectioned without damage to the ultramicrotome knives

There are two film types–the homopolymer ACLAR® Rx Series and the copolymers ACLAR® 33C.

ACLAR® 33C is a copolymer film consisting primarily of chlorotrifluoroethylene (CTFE). It offers an outstanding moisture barrier, excellent chemical resistance and minimal dimensional change (±2%), making it the best choice for use in microscopy.

Aclar® UltRx 2000 is a 2.00 mil (51 micron) PCTFE homopolymer, high performance barrier film for the pharmaceutical and medical markets. It thermoforms well on conventional blister packaging equipment and provides the best barrier of any clear film.
