What is the performance of acrylic plexiglass processing products

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. Its shrinkage range is decreasing, generally between 0.45% and 0.9. Therefore, it provides good conditions for the molding accuracy of acrylic production. Generally, the molding is It is very precise.

3. The adaptation range of polymethyl methacrylate to ambient temperature does not have ordinary fluidity, but non-Newtonian fluidity. Therefore, when the temperature is high, the viscosity of plexiglass will be reduced. Will decrease, which is the performance of plexiglass very sensitive to temperature. 4. The temperature of plexiglass in the flow process is generally around 150°C, but when the plexiglass begins to decompose, the temperature is higher than 270°C, so it is still very flexible in terms of temperature changes and will not be affected. Produced under the influence of temperature, high temperature resistance is a 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 in quality. This feature is not available in glass, so acrylic can withstand various environments of high temperature and low temperature. Consumers don't have to worry about temperature during the production process.
