Acrylic plank in our daily lives is often used to, then acrylic slab in the daily environment temperature adaptability how it? Today Shanghai Qin Sheng acrylic will simply tell you about. 

1, cresol acrylic slab is made of polymethyl methacrylate, polymethacrylic acid containing polar side-methyl-p-cresol, having strong moisture absorption, water absorption is generally in the acrylic sheet must be kept dry, the drying conditions need dried 5-6h at 78 ℃ -80 ℃.

2, by the polymethylmethacrylate cresol adapt to the ambient temperature range does not have a common fluid resistance, but has a nonNewtonian fluid, and therefore at a temperature high, plexiglass solvent viscosity will decrease, which is acrylic products very sensitive to temperature performance.

3,acrylic polymer is an invisible, its contraction range are reduced, usually at 0.45% -0.9, so for the production of acrylic products when precision molding provides good conditions, the general situation By molding it is very precise. 

4, acrylic temperature in flowing process generally around 150 ℃, but when the acrylic begins to decompose when the temperature is higher than 270 ℃, so that aspect of the change in temperature is very flexible and will not be temperature the impact of production, high temperature resistant plexiglass properties. Acrylic slabs with good cutting performance, under clear conditions in the amount of a good size for processing by laser cutting, in general, acrylic slab can withstand high and low temperatures to the environment, acrylic slab is still very resistant to temperature。
