Biaxially stretch practically anything.

The latest lab machine for biaxial film stretching from Bruckner Inc., Greenville, S.C., is configured with three ovens instead of two, allowing it to simulate product development with a sequence of three different oven temperatures. Oven number one heats and stretches; oven number two stretches and anneals; oven number three anneals and relaxes. Three ovens are optimal for biaxial film development in general, but are required to stretch some specialty materials like PLA, cyclic olefin copolymers, PVOH, polyimide, PTFE, and triacetate. Biaxially stretched polyimide is used on circuit boards and can withstand temperatures up to 572 F. Biax triacelate, made by only a couple of companies in the world, is for flat panel displays. Bruckner's Karo IV lab machine will demonstrate stretching some of these exotic new films at NPE. Tel: [phone] * PT Direct: 343TF
