Expansion and contraction:
Taking an acrylic sheet 1000mm in length for example.
In summer(40.C),It'll lengthen to 1002,In winter (-30.C),It'll shorten to 997mm.
Notice for acrylic:
Temperature:Acrylic will soften on heating to 100.C or above. So it should be above 100.C.
Defect:Since acrylic surface hardness is similar to aluminum,so the surface protection should be noticed. If detect occurred,it should be used yellow aluminum to polish.
Scratching:Since electrostatic will occur by dry cloth,if there is dust on surface,it should be washed lightly by 1% soap water by soft cloth.
Heat Expansion:The index for heat expansion of acrylic is large and its extensibility is several times than that of metal,therefore it should be considered when installation.
