| polystyrene sheet PS sheet: Polystyrene sheet and Acrylic sheet PMMA sheet are a good succedaneum of glass. 1. It is light, its weight is only half of the common glass. 2. It is a kind of polymer compound, and its molecular chain is soft, so plexiglass is wit h high strength. Its impact resistance is 7 times--17 times of the common glass. 3. It is ageing resistance. 4. It is tasteless and non-toxic. 5. It is easy to be cleaned. 6. It can be recycled, it is good for the environment protection.
