PFA Films

PFA Films

PFA Films have an extremely high continuous service temperature of 260 degrees Celsius or 500-degree Fahrenheit. PFA is short for perfluoroalkoxy which is a fluoropolymer resin. PFA resin can be heat sealed and thermoformed as well as metalized. It can also be laminated to a variety of materials for use in end user applications as well as used as a hot melt adhesive. The appearance of PFA is generally clear or translucent and has very similar characteristics such as performance to PTFE (Polytetrafluoroethylene).

PFA has excellent clarity and durability as well as excellent dielectric properties. The temperature range of PFA film is equally impressive operating as low as -73 degrees Celsius.

PFA Films Uses

PFA is virtually chemically inert. If the application requirements demand a high temperature and chemical resistance product PFA is well suits. An example of applications are uses with rapture disks, chemical pumps, linings for tanks, shrink roll covers and gaskets.

Due to the durability and flex / crack resistance it is suited for use in flat cables and circuit board manufacture as well as diaphragms.

Grades of PFA Films

There are generally two grades of film to choose from. These are welding grade (PFA WG) and premium grade (PFA PG).

Welding grade film can offer a saving over premium grade of around 15%. It still exhibits all the properties you would expect from a PFA such as mechanical, physical and thermal.

Premium grade is PFA in its purest form, often called virgin PFA. This is made with 100% PFA resin and has a melt flow index (MFI) range of 1.5 – 2.5.

We can offer rolls at 12kg on short lead times. The main thicknesses are 0.05mm (0.002”) and 0.125mm (0.005”). Standard widths are 1220mm and 1524mm.
