PMMA is also called acrylic, are the English acrylic Chinese call, the translation is actually plexiglass. The chemical name is polymethyl methacrylate. Hong Kong people are mostly called acrylic, is an early development of an important thermoplastic, with good transparency, chemical stability and weather resistance, easy to dye, easy processing, beautiful appearance, in the construction industry has a wide range of applications.

Material characteristics: PMMA material has a hard texture, not easy to break, highly transparent, good weather resistance, easy to dye and molding, etc., become widely used in the transparent hope material material. The important acrylate resin is polymethyl methacrylate (P2 MMA), commonly known as organic glass, industrial production in 1932.

In terms of molecular structure, Pmma is a linear thermoplastic with a macromolecular backbone similar to that of PE. Usually, the free radical polymerisation yields the pmma structural unit. The methyl and methyl ester groups on the carbon atoms destroy the spatial regularity of the molecular chains, and the macromolecular chains are in a random configuration, which is a typical non-walking polymer.

In addition, the Pmma is biaxially stretched above Tg to form a highly ordered oriented state structure, which can improve the impact strength and stress cracking resistance of the products, and can eliminate silver patterns and obtain oriented plexiglass products.

Acrylic uses:

Acrylic has the advantages of light material, low price, easy to form, simple process, low cost, etc. Therefore, it is gradually widely used, not only in building materials, but also widely used in instrument parts, car lights, optical lenses, etc.

1、Industrial equipment: instrument surface plate, cover, etc.

2、Advertising facilities: light box, signboard, signage, display stand, etc.

3、Transportation facilities: trains, cars, taxis and other vehicles doors and windows, etc.

4、Medical equipment: baby incubators, various surgical medical instruments, etc.

5、Construction materials: windows and doors, soundproof doors and windows, light covers, * kiosks, fluorescent lamps, palm lamps, sanitary facilities, integrated ceiling, partitions, screens.
