The use of a wide range of acrylic sheet products, we can say in our daily lives can often be seen. But we should pay attention to the temperature of acrylic products can withstand what is, to answer them below:
1, acrylic article is made from polymethyl methacrylate-cresol, p-cresol-containing polymethacrylate polar side group, with a strong hygroscopic property and water absorption in the acrylic sheet generally must be kept dry, 78 need dried 5-6h dried under ℃ -80 ℃.
2, acrylic polymer is an invisible, its scope are reduced shrinkage, are generally in the 0.45% -0.9, so the time for the production of acrylic products provide good precision molding conditions are generally formed is very accurate.
3, the polymethyl methacrylate-cresol adaptation range of the ambient temperature of the fluid does not have a general, but has a non-Newtonian fluid, and therefore at high temperature, the melting viscosity of the plexiglass will be reduced, which is Acrylic very sensitive to temperature performance.
4, Acrylic temperature in the flow of the process are 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 still very flexible and will not be temperature the impact of production, high temperature is characteristic of plexiglass.
