Dimensional Stability

Dimensional stability is the ability of a material to maintain its essential or original dimensions when subjected to varying degrees of temperature, moisture, pressure, or other stress. The inherent material properties as well as the manufacturing conditions determine the dimensional stability. The following materials have improved stability due to inherent low water absorption and thermal expansion properties. Additionally, when manufactured with Westlake Plastics compression molded technology, these products have low internal stress, which improves stability during machining; resulting in decreased machine time and reduced secondary annealing and reprocessing.
