The HAUL-OFF system measures the extensional properties of polymer melts by drawing a vertical melt strand at a constant HAUL-OFF speed or with a linear or exponentially accelerating velocity.
The HAUL-OFF system measures the extensional properties of polymer melts by drawing a vertical melt strand at a constant pull-off speed or with a linear or exponentially accelerating velocity. The HAUL-OFF system measures the force needed to elongate the strand, and calculates elongation stress, draw ratio and apparent elongation rate and viscosity.
