Extrusion Conditions

Table 16 shows an example of the co-extrusion molding conditions for a Nylon-MXD6/Nylon 6 mixture for making laminated films. Table 17 shows an example of a similar molding process using a Nylon-MXD6/polypropylene mixture for forming laminated sheets. Table 18 shows an example of a similar molding process using a Nylon-MXD6/high density polyethylene for producing laminated blow bottles.
Contact MGC for further details about the selection of various materials.
