ACLAR® Fluoropolymer-Film, 210x297mm (DIN A4), 51µm thick (2mil)

ACLAR® is made from fluorinated-chlorinated resins. There are four basic film types–the homopolymer ACLAR® Rx Series, the new ACLAR® UltRx and the discontinued copolymers ACLAR® 22A and 33C (Honeywell). 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® UltRx is a PCTFE homopolymer film. It offers an outstanding moisture barrier, excellent chemical resistance and small dimensional change (<6%). It is crystal clear, biochemically inert, plasticizer and stabilizer free. It is successfully used to grow cells, perform high-pressure-freezing (HPF) and for embedding.

Features

• 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 211°C (403°F)– stable in the SEM.
• Flexible and soft– can be sectioned without damage to the ultramicrotome knives.
• Stable for use with High Pressure Freezing.

ACLAR® film is available in 2 mil (51µm) thickness and it is offered in DIN A4 (210x297mm) sheet form with package quantities of 10 or 25.
