Atofina: New PVdF copolymer for polyolefin extrusion
A new PVdF copolymer is said to work especially well as a processing aid for extrusion of LLDPE, HDPE and PP films. When added at levels of only 0,02-0,08%, Kynar Flex PPA from Atofina Performance Polymers is said to help increase processing speed while reducing energy consumption, processing temperatures and melt pressure. It also helps prevent blockages in equipment and formation of drops and knots on converting lines. The product has been shown to enhance a film’s transparency and mechanical properties and to eliminate melt fracture and “sharkskin” surface defects. The product is also suitable for use in pipe and cable sheathing.
