Extrusion Notes
Equipment used to process this resin should be constructed of corrosion resistant materials. Dies and adapters are
recommended to be stainless and/or duplex chrome or nickel plated.
Notes
These are typical values and are not be construed as specifications. The physical properties are highly dependent on the
manufacturing conditions. So customers should confirm performances by their own tests.
