Acrylic also has a kind of recycled material that uses recycled acrylic trim, which is thermally degraded to obtain regenerated MMA (methyl methacrylate) monomer, which is then obtained by chemical polymerization. After a rigorous process, the pure MMA monomer can be re-purchased, and there is no difference in quality from the new synthetic monomer. However, the purity of the degraded monomer produced is not high, and the quality and performance of the sheet are poor after molding.

The extruded plate is made of granular raw materials, which are extruded after high temperature dissolution, and the cast plate is directly cast by MMA monomer (liquid). Although the shape of the extruded plate is relatively smooth and smooth, it is completed because the pellet material is formed. polymerization. When processed into sheet metal, its structure and performance are weak, and it is not suitable as a material for outdoor signage products. It is only suitable for indoor products such as crystal characters or product holders.

In addition, since most of the extruded plates do not have the function of preventing ultraviolet rays, the life of the outdoor use is not the same as that of the cast plate, the color will gradually fade and it will be easily embrittled until it is broken. The cast sheet is structurally polymerized during the processing of the sheet, with the addition of UV absorbers, which have extremely high strength and UV function. The outdoor service life is more than 5 years and even 10 years. The color is always bright and new during use.
