3M Medical Tape 9833, Polyethylene Polyurethane Barrier
A single sided, breathable liquid barrier tape with a thin conformable backing coated in acrylic adhesive, supplied on a white carrier for device assembly.
This Medical Tape, catalog number 9833, is a single sided liquid barrier tape used in the manufacture of health care medical devices. It consists of a liquid barrier, breathable, thin, conformable backing made from polyethylene and polyurethane, coated on one side with a pressure sensitive acrylic adhesive.
The tape is provided on a white carrier, described as giving it a premium appearance suited to visible or cosmetic components of a finished device. Its combination of liquid barrier protection and breathability makes it appropriate for applications where a device needs to resist moisture ingress while still allowing some vapour transmission, such as certain wearable or diagnostic device housings.
Because the backing is thin and conformable, it can adapt to slightly contoured surfaces during assembly. This tape is intended for use by medical device manufacturers during production rather than as a stand alone clinical dressing. Distributors supplying device makers keep this catalog number available to support builds that call for this specific barrier and adhesive combination.
