          Plexiglass products for its high transparency, low price, easy machining, etc. are widely used, plexiglass products are usually glass alternative materials frequently used, here to tell you about from plexiglas adaptability to the environment:
          1, plexiglass article is made of polymethyl methacrylate cresol, p-cresol containing polymethacrylate polar side group, has strong moisture absorption, water absorption is generally in the acrylic sheet must be kept dry, drying conditions need dried 5-6h at 78 ℃ -80 ℃.
          2, plexiglass products is an invisible polymer shrink its range are reduced, usually at 0.45% -0.9, so the time for the production of precision molding of acrylic provides very good condition, under normal circumstances forming They are very precise.
          3, due to polymethylmethacrylate cresol adapt to the ambient temperature range does not have a common fluid resistance, but has a non-Newtonian fluid, and therefore at a high temperature, the solution viscosity plexiglass products will be reduced, which is organic glass products very sensitive to temperature performance.
          4, plexiglass products in the flow of the process temperature is generally about 150 ℃, but when plexiglass products begin to break down when the temperature is higher than 270 ℃, so that aspect of the change in temperature is very flexible, not will be affected by temperature and the production of high temperature is a characteristic of plexiglass.
          5, plexiglass products also has good cutting performance, under clear conditions in a good amount of size for processing by laser cutting, high quality and simple, this feature is not available in glass, acrylic and therefore can withstand all kinds of high and low temperatures environment, consumers do not have to worry about the production process temperature problem.
          Plexiglass products used in everyday life is dazzling, as with pearl buttons made of plexiglass products, toys, lamps also because of the color plexiglass decorative role, but it is particularly beautiful and dazzling.
