Acrylic is an invisible polymer. Because of its unique physical properties, it has certain requirements on ambient temperature and humidity. So what are the requirements for ambient temperature when processing acrylic products? The following editor will introduce to you.
    1. Acrylic is an invisible polymer, and its shrinkage range is decreasing, generally between 0.45% and 0.9%. Therefore, the molding accuracy of acrylic products provides a great Good conditions, under normal circumstances, the molding is very accurate.
    2. Acrylic products are made of poly cresol methacrylate. Poly cresol methacrylate contains polar side methyl groups and has strong moisture absorption performance. Generally, the water absorption rate must be kept dry in acrylic sheets. The conditions for drying are Dry for 5-6h at 78℃-80℃.
3. The temperature of acrylic in the flow process is generally around 150°C, but when the acrylic product 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 by temperature. High temperature resistance is the characteristic of acrylic.
4. Acrylic products made of polymethyl methacrylate do not have ordinary fluidity to the ambient temperature, but non-Newtonian fluidity. Therefore, when the temperature is high, the viscosity of acrylic will decrease. This is acrylic The product is very sensitive to temperature.
    Acrylic products have good cutting performance and can be processed by laser cutting with a good size. Therefore, acrylic products can withstand high temperature and low temperature environments. Generally, there is no need to worry about temperature during the production process.
    The above is about the environmental temperature requirements during the processing of acrylic products. I hope it can help everyone.
