In general, the high temperature resistance of acrylic sheets is not high, generally only resistant to temperatures of 90 degrees Celsius or less. When the acrylic sheet stays for a long time in an environment where the temperature exceeds between 60 degrees Celsius and 95 degrees Celsius, the acrylic sheet is prone to slight deformation. Acrylic sheet cold resistance is also relatively poor, embrittlement temperature of about 9.2 degrees Celsius.
1. Acrylic products have a very good cutting performance, you can measure the size of the clear situation through laser cutting for processing, so acrylic products can withstand high and low temperatures in a variety of environments, consumers in the production process simply do not have to worry about the temperature problem.
2. acrylic is an invisible polymer, its shrinkage range are decreasing, generally in 0.45% -0.9, so acrylic products are produced when the molding accuracy is very precise.
3. Acrylic products are made of polymethacrylic cresol, polymethacrylic cresol contains polar side methyl, with strong hygroscopic properties, water absorption in general in the acrylic sheet must be kept dry, drying conditions required is 78 ℃ – 80 ℃ dry 5-6h.
4. Acrylic in the flow of the process of temperature are generally around 150 ℃, but when the acrylic products began to decompose, the temperature is higher than 270 ℃, so that the change in temperature is still very flexible, will not be affected by the temperature of the production, high temperature resistance is the characteristics of acrylic.
