1. Plexiglass is made of poly cresol methacrylate. Poly cresol methacrylate contains polar side methyl groups, which has strong moisture absorption performance. Generally, the water absorption rate must be kept dry in acrylic sheets. The drying conditions are 78 Dry at ℃-80℃ for 5-6h. 2. Plexiglass is an invisible polymer, and its shrinkage range is decreasing, generally 0.45%-0.9, so it provides good conditions for the molding accuracy of acrylic production, and it is generally molded. All are very precise. 3. The adaptation range of polymethyl methacrylate cresol to ambient temperature does not have ordinary fluidity, but non-Newtonian fluidity. Therefore, under the condition of high temperature, the viscosity of plexiglass will be reduced. Very sensitive to temperature performance.
Fourth, the temperature of plexiglass in the flow process is generally around 150 ℃, but when plexiglass begins to decompose, the temperature is higher than 270 ℃, so the temperature change is still It is flexible and will not be affected by temperature. High temperature resistance is the characteristic of plexiglass. 5. Plexiglass also has good cutting performance. It can be processed by laser cutting with good size and clear conditions. It is simple and high-quality. This feature is not available in glass, so acrylic can withstand high temperature and low temperature environments. , Consumers don’t have to worry about temperature at all during the production process.
