Dimensional Stability (Shrink, Warp, & Thermal Expansion) Long fiber reinforced composites also exhibit reduced thermal expansion compared to unreinforced plastics of the same type due to their internal network of reinforcing fibers providing resistance to deflection and form changes.

Recently announced 30% expansion of quarterly dividend and plan to raise the company's annual dividend 60% cumulatively over the next three years for the third quarter driven primarily by 5% organic expansion and recent specialty acquisitions, which added 4%. Richardson continued, "Our recently announced dividend expansion is our largest ever, and our three-year plan of a 60% cumulative increase reflects the important steps we have taken to further strengthen our portfolio, balance sheet and future cash flows. 

We continue to deliver margin expansion in all three segments from pricing actions, improved mix and cost reductions," said
