Celanese VECTRA V143LC LCP, 40% Specialty
Categories: Polymer; Thermoplastic; Liquid Crystal Polymer (LCP); Liquid Crystal Polymer (LCP), 40% Glass Fiber Filled

Material Notes: High Weldline strength, low warpage, 40% glass reinforced.
VECTRA should in principle be predried. Because of the necessary low maximum residual moisture content the use of dry air dryers is recommended. The dew point should be =< - 40° C. The time between drying and processing should be as short as possible.
For subsequent storage of the material in the dryer until processed the temperature does not need to be lowered for grades A, B, C, D and V (<= 24 h).
