Acrylic withstands weak acids, bases and a number of non-polar solvents. But acrylic does not cope with strong acids, bases or polar solvents such as acetone or chloroform. This picture shows a piece of 3 mm laser cut acryllic which was dipped in acetone right after the cutting resulting in crackled edges. Simular results will occour with benzine or alcohol.   Water absorption in acrylic is limited and it is relatively easy to dry. Water can still cause an acrylic sheet to warp however, if for example the sheet becomes wet on one side – in the same as wood will warp.
