PMMA Zhenjiang Chimei CM-211 injection molding transparent acrylic plastic for electronic and electrical appliances

PMMA concept:

 The chemical name is polymethylmethacrylate, which is a polymer compound polymerized by methyl methacrylate. It is an important thermoplastic developed earlier. Plexiglass is divided into colorless transparent, colored transparent, pearlescent and embossed plexiglass. Plexiglass is commonly known as acrylic, Zhongxuan acrylic and acrylic. Plexiglass has the advantages of good transparency, chemical stability, mechanical properties and weather resistance, easy dyeing, easy processing and beautiful appearance. Plexiglass is also called gelatin glass, acrylic, etc.

 PMMA performance:

 1.High transparency. Plexiglass is an excellent polymer transparent material with a light transmittance of 92%, which is higher than that of glass. The tube of the solar lamp called artificial small sun is made of quartz because quartz can completely pass through ultraviolet rays. Ordinary glass can only pass through 0.6% UV, but plexiglass can pass through 73%.

2. High mechanical strength. The relative molecular weight of plexiglass is about 2 million. It is a long-chain polymer compound, and the chain forming the molecule is very soft. Therefore, the strength of plexiglass is relatively high, and the tensile and impact resistance is 7-18 times higher than that of ordinary glass. There is a kind of plexiglass treated by heating and stretching, in which the molecular segments are arranged in a very orderly manner, which significantly improves the toughness of the material. Nail into the plexiglass, even if the nail penetrates, there is no crack on the plexiglass. This kind of plexiglass will not break into pieces after being punctured by the bullet. Therefore, the stretched plexiglass can be used as bulletproof glass and cockpit cover on aircraft.

3. Light weight. The density of plexiglass is 18G / cm3;, The weight of materials of the same size is only half of that of ordinary glass and 43% of that of metal aluminum (a light metal).

4.Easy to process. Plexiglass can not only be cut by lathe and drilled by drilling machine, but also be bonded into various shapes with acetone, chloroform and other instruments. It can also be processed into all kinds of products ranging from aircraft cockpit cover to dentures and dentures by plastic molding methods such as blow molding, injection and extrusion.

PMMA benefits:

1, Aesthetics of plexiglass: mirror effect, exquisite workmanship, no wrinkles and joints;

2, Visual effect of plexiglass: various colors and strong visual impact;

3, Light transmittance of plexiglass: the light transmittance can reach 96%, and the light transmittance and light are relatively soft;

4, Impact resistance of plexiglass: more than 200 times that of ordinary glass products, and there is almost no risk of fracture;

5, Durability of plexiglass: the product has good protection for the built-in light source and prolongs the service life of the light source product;

6, Weather resistance of plexiglass: it can be guaranteed not to fade, and the service life of high-quality plates is as long as 6-13 years;

7, Fire resistance of plexiglass: no spontaneous combustion and self extinguishing;

8, Energy saving performance of plexiglass: it has very good light transmittance, relatively reduces light sources, saves power and reduces the cost of use;

9, Rationality of plexiglass: reasonable design, rain proof and moisture-proof, open structure, convenient for cleaning and maintenance, etc.

PMMA application:

1. Architectural application: window, soundproof door and window, daylighting cover, telephone booth, etc

2. Advertising application: light box, signboard, signboard, exhibition rack, etc

3. Transportation application: doors and windows of trains, automobiles and other vehicles

4. Medical application: baby incubator, various surgical medical instruments, civil goods: sanitary facilities, handicrafts, cosmetics, supports, aquariums, etc

5. Industrial application: instrument panel and cover, etc

6. Lighting application: fluorescent lamp, chandelier, street lamp cover, etc

7. Household application: fruit tray, tissue box, acrylic art painting and other household daily products.
