Acrylic Sheet Shrinkage

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

Acrylic sheet shrinkage.

Parts made from multiple pieces of acrylic are usually joined together using solvents that melt each. Simple bends can be made by heating the bend point with a wire heater.

Acrylic sheet is also more flexible than glass and many other building materials. One major difference between acrylic and glass is that acrylic does not shrink with age. Differential shrinkages are not considered. Modify the timing as necessary.

This contraction is partly due to the difference of density of polymers from the melt state and the cooled rigid state. Most of the plastic molded part shrinkage occurs in the mold while cooling.

Or the entire sheet can be heated and draped or forced to take the shape of a desired form.

Some shrinkage may occur when general purpose acrylite is heated to forming temperature but post forming stability is exceptional. Acrylic sheets can be relatively easily heated and formed to a desired shape. For thicker sheets it will take longer and for thinner sheets it will take less time.
