  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.   Application (1) building insulation, door window, , telephone etc (2) lighting, advertising signs, signs, exhibition, etc (3) Medical applications: various surgical incubator medical appliances and products: bath facilities, handicraft, cosmetics, bracket and aquatic animals box, etc (4)Sculpture and signboard (5)Make kitchen and Sanitary application
