The Center for Advanced Engineering, Fibers and Film at Clemson University in Clemson, S.C., has developed a simulation model for the molecular behavior of LDPE and LLDPE in blown film and is making it available to processors for free in exchange for feedback on how it performs.

The Center for Advanced Engineering, Fibers and Film at Clemson University in Clemson, S.C., has developed a simulation model for the molecular behavior of LDPE and LLDPE in blown film and is making it available to processors for free in exchange for feedback on how it performs. CAEFF says the monolayer model will shorten product development and help optimize production parameters. It can also be used for training. In the example shown, the simulation indicates degree of crystallinity in a blown film bubble related to distance from the die.

CAEFF plans to sell a commercial version with broader capabilities. Tel: (864) 656-6557 . www.clemson.edu
