Which is better used as roof, hollow polycarbonate sheet or plexiglass? This is the question of many customers who are still hesitating. Now let's learn about these two products together.
The chemical name of organic glass is polymethyl methacrylate. It is a high molecular compound composed of methyl methacrylate. It is an important thermoplastic plastic which was developed earlier. Organic glass is divided into colorless transparent, colored transparent, pearlescent, embossed organic glass.Its weakness is precisely the fatal weakness: fragile, not easy to make heavy products, can not make hollow products, and the surface is not easy to handle, easy to stain with water.
And, the glass product temperature tolerance is poor, easy to be subjected to temperature difference changes and burst. In addition, although fashion is strong, it is also easy to be out of date. Of course a little also cannot ignore, the transparent feeling of glass is very good, pollution-free, fashionable aspect is strong, modelling is rich apply widely, but to practical very poor.
First of all, the hollow polycarbonate sheet is made of polycarbonate material. The hollow polycarbonate sheet is usually a double-layer structure, and the panel with a thickness of more than 10mm is a multi-layer and heteromorphic structure.The transmittance reached 89%.Resistance to cold and heat, and 40 ℃ ~ 120 ℃, sunshine board does not produce deformation. Its own ignition point is 580 ℃, from the self-extinguishing fire, burning does not produce poisonous gas, don't feed the fire from spreading.
We start with the flame retardancy of the two products. Organic glass is PMMA polymethyl methacrylate material, also known as acrylic. The light transmittance can reach 92%. It is not self-igniting but it is inflammable and has no self-extinguishing property. The average hardness is 8, 9 degrees. Heat resistance is not high, continuous use will cause heat distortion when temperature over 90 ℃. Cold resistance is poorer, brittle temperature is about 9.2 ℃.
