Die Lip Treatment for Elimination of Melt Fracture in Film Extrusion, 2001 Polymers Laminations & Coatings Conference Proceedings
Jae Jin Baik--A proprietary lip treatment eliminates or greatly reduces the onset of melt fracture in polymer processing applications. The No-Frac ® treatment has been shown to reduce or eliminate the use of process aid, reduce die pressures and reduce the time to clean die lips. The treatment is durable for more than one year of trouble-free operation. This presentation describes the performance of the treatment for blown film applications.
