Acrylic Sheet Shrinkage

The shrinkage of plastics signifies the volume contraction of polymers during the cooling step of the processing of polymers.

One major difference between acrylic and glass is that acrylic does not shrink with age. Acrylic sheets can be relatively easily heated and formed to a desired shape. Users should always refer to the processing data sheets provided by the material supplier.

Some shrinkage may occur when general purpose acrylite is heated to forming temperature but post forming stability is exceptional. Or the entire sheet can be heated and draped or forced to take the shape of a desired form. Differential shrinkages are not considered. This article uses a sheet about 1 4 thick so all times are about 10 to 15 minutes per step.

This contraction is partly due to the difference of density of polymers from the melt state and the cooled rigid state. Modify the timing as necessary. The only major variable that can affect the forming process is the thickness of the plastic sheet. For thicker sheets it will take longer and for thinner sheets it will take less time.

Parts made from multiple pieces of acrylic are usually joined together using solvents that melt each. Most of the plastic molded part shrinkage occurs in the mold while cooling.
