Nylon compositions adequate for blow molding

It has now been found that a unique combination of additives makes semi-crystalline polyamides readily processible by extrusion blowmolding to make hollow, stiff parts of various shapes. The compositions consist essentially of semicrystalline polyamide, a selected toughening agent and an anhydride-r...

Zusammenfassung:	It has now been found that a unique combination of additives makes semi-crystalline polyamides readily processible by extrusion blowmolding to make hollow, stiff parts of various shapes. The compositions consist essentially of semicrystalline polyamide, a selected toughening agent and an anhydride-rich ethylene copolymer, and a fibrillar polytetrafluoroethylene.
