The chemical name polymethyl methacrylate is polymerized by methyl methacrylate monomer MMA. Referred to as PMMA, commonly known as acrylic, Sian Garli. PMMA is a thermoplastic, density 1.19-1.20, with extremely high transparency, high transmittance of 91% -93% can via 99%, ultraviolet light 72%, light weight, anti-fragmentation performance is ordinary silicon glass 12-18 times, mechanical strength and toughness are greater than 10 times of ordinary glass, and the hardness terminal is added to the top of the surface, and the surface hardness of the surface is reachaised by 5 h, anti-scratch, with highlighting weather resistance and aging. Low temperature (-50-60 ° C) and higher temperatures (100 ° C or lower) impact strength constant, good electrical insulation properties, can resist arc, chemical properties, and resistant chemical corrosion. PMMA material is common thickness of 0.5, 0.65, 0.0, 1.0, 1.2, 1.5, 2.0, 3.0mm. The material color has other colors in addition to transparent, and the surface of the sheet can be made of coating treatment, Ni, Cr, Al, etc. Light rate can be specified according to customer.

The PC is a polyvalent, polycarbonate is Polycarbonate, referred to as PC engineering plastics, PC material is actually one of our engineering plastics, as a widely used material, PC has its own Features and advantages and disadvantages, PC is an uncomalated amorphous thermoplastic resin with excellent electrical insulation, elongation, dimensional stability and chemical resistance, high strength, heat resistance and cold resistance. It also has the advantages of self-extinguishing, flame retardant, non-toxic, colorless, colorless, can see the shadow of PC plastics in the various corners of your life, and the characteristics of large-scale industrial production and easy processing are also extremely low. Its intensity can satisfy the various needs from mobile to bulletproof glass. The disadvantage is that it is difficult than metal, which causes its appearance to be easily scratched, but its strength and toughness are very good, whether it is a heavy pressure or a general fall. As soon as you don't try to use the stone, it will live longer. The surface hardness of the surface treated PC has been greatly improved, and the hardness of the pencil is generally around 2 hours after improved PC surface. The common thickness of the PC sheet is 0.12, 0.18, 0.25, 0.38, 0.5, 0.65, 0.8, 1.0, etc. The surface of the PC sheet is also adapted to various occasions, and the matte mist surface, transparent sand, such as HP12, HP40, HP60, 8A35, 8B35, and the like of the US GE.

Recently, composite sheets have also appeared on the market, as the name suggests, such materials are complicated together for both PMMA and PC, partially combined with the above two sheet advantages, and the surface hardness can reach the surface hardness of the acrylic breeze. It also has the toughness of the PC sheet to withstand the impact of greater strength.

Acrylic and PC sheet products are short-volume production due to short development cycles, and adapt to small batches of production, making product shape dimensional changes, can also achieve steps of steps, assembly bay, and can be processed. After the PC material is treated, the surface can be made into a variety of textures such as CD ripples, hair ribs, drawing ribs.

PMMA and PC materials are now widely used in various high-grade digital products window protected lens, ultra-thin buttons, surface decorative parts, etc.
