Acrylic is plexiglass, and the English abbreviation is PMMA. It is an important plastic polymer material developed earlier. It has good transparency, chemical stability and weather resistance. It can be exposed to the external environment for a long time, and its optical and mechanical properties will not degrade it. The acrylic table lampshade has good toughness, is not easy to break, and has strong repair ability. The light transmittance can reach 92%, but it is not scratch-resistant, complicated in process and high in cost.
Ceiling shades are amorphous, odorless, non-toxic, highly transparent colorless or pale yellow thermoplastics with excellent physical and mechanical properties, especially excellent impact resistance, high tensile strength, flexural strength and compressive strength ; Small creep, dimensional stability; good heat resistance and low temperature resistance, stable mechanical properties, dimensional stability, electrical properties and flame retardancy in a wide temperature range can be in the temperature range of -60 to 120 ℃ In the long-term use, there is no obvious melting point, in the molten state of 220-230 ℃.
Acrylic lampshade manufacturers due to polymer chain stiffness and resin melt viscosity, low water absorption, low shrinkage, high dimensional accuracy, good dimensional stability, film permeability, self-extinguishing material, light stability, but not UV resistant. Good weather resistance, oil resistance, acid resistance, strong alkali resistance, oxidizing acids and amines, ketones, soluble in chlorinated hydrocarbons and aromatic solvents, easy to hydrolyze, easy to crack in water;
