Notice for Acrylic:
Temperature: Acrylic will soften on heating to 100℃ or above, so it should be avoided to be used above 100℃. (The Ultimate temperature of continuous operation is 80℃)
Defect: Since acrylic surface hardness is similar to aluminum, so the surface protection should be noticed. If defect occurred, it should be treated with the abradant that used for 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 install.
