Dimensional stability of acrylic

The dimensions of acrylic does not change significantly over time, hence many measuring instruments is manufactured in acrylic. But attention is required when used in conjunction with other materials, because acrylic expands a lot with rising temperatures (acrylic expands 5 times more than steel). An acrylic pole at 1 meter becomes 0.7 mm longer if the temperature raises 10 degrees. If acrylic is fixed in a steel frame, there is a high probability that the acrylic will crack if the temperature changes. Akryl
