ACLAR® is made from fluorinated-chlorinated resins. There are four basic film types–the homopolymer ACLAR® Rx Series, the copolymers ACLAR® 22A and 33C and the new ACLAR® Cx. (Honeywell/Allied Signal). The chemical make-up of all ACLAR® products 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.
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.
- Crystal clear, high UV transparency– ideal for use in UV curing of embedding resin in microscopy.
- Chemically stable and biochemical\y 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.
ACLAR® 33C Film
ACLAR® 33C film is now available in 7.8 mil (199µm) thickness and it is offered in a 8” x 10” sheet form with package quantities of 10 or 25.
