First, the plexiglass is made of polymethyl methacrylate, polymethyl methacrylate containing polar side methyl, with a strong hygroscopic properties, water absorption in the acrylic sheet must always be kept dry, dry conditions required is 78 Dried at -80 ° C for 5-6 h.
Plexiglass is an invisible polymer, its shrinkage range is reduced, are generally in the 0.45% -0.9, so the acrylic production time for the molding accuracy provides a very good condition, under normal circumstances Are very accurate.
Third, from the polymethyl methacrylate to the ambient temperature of the adaptation range does not have a common fluid, but with non-Newtonian fluid, so the case of high temperature, plexiglass will reduce the viscosity, which is plexiglass Very sensitive to temperature performance.
4, plexiglass in the process of flowing the temperature are generally around 150 ℃, but when the plexiglass began to break down when the temperature is higher than 270 ℃, so that the temperature changes are still very flexible, will not be The impact of temperature and production, high temperature is the characteristics of plexiglass.
5, plexiglass also has a good cutting performance, can be measured in a good size under the conditions of laser cutting processing, simple high quality, this feature is not available glass, so the acrylic can withstand high temperature and low temperature of various environments , Consumers in the production process do not have to worry about the temperature problem.
