PMMA (polymethyl methacrylate) English name: PolymethylMethacrylate. PMMA resin is non-toxic and environmentally friendly material that can be used to produce tableware, sanitary ware, etc., have good chemical stability, and weatherability. PMMA resin is not easy to produce sharp in broken fragments, the United States, Japan and other countries and regions have been made mandatory in the law, schools and kindergartens architectural glass must be used PMMA resin. At present, all over the country to speed up the pace of urban construction, street signs, advertising light boxes and telephone booths, large numbers, in which a considerable portion of the material used is PMMA resin. Beijing Olympic project building outdoor color green also makes extensive use of PMMA resin.Gather methyl methacrylate (mma), with acrylic acid and its ester polymerization of acrylic polymer referred to get such tree ester, corresponding plastic collectively polyethylene acid plastic, among them with poly (methyl propylene methyl ester most widely used. Gather methyl methacrylate (mma) abbreviation code PMMA, plexiglass, is by far the most transparent material texture synthesis of excellent, price and more suitable varieties. Application: PMMA soluble in organic solvent, such as phenol, benjia ethers, through the spin coating can form a good film, has the good dielectric properties, as there is an airport effect tube (OFET) is also called the organic thin-film transistors (OTFT) medium layer.
Typical Applications
Automotive industry (equipment, lights, instrument panel, etc.), pharmaceutical industry (blood storage containers, etc.), industrial applications (DVD, light scattering device), key electronic products (especially transparent). Consumer goods (beverage cups, stationery, etc.). PMMA dissolved in organic solvents, such as phenol, anisole, etc., can be formed by spin-coating a good film with good dielectric properties, can be used as organic field effect transistor (OFET), also known as organic thin film transistor (OTFT) dielectric layer .
Chemical and Physical Properties
PMMA has good optical properties and resistance to climate change features. White light penetrating up to 92%. PMMA products with very low birefringence, particularly suitable for making VCDs. PMMA has a room temperature creep. As the load increased, the time growth can lead to stress cracking phenomenon. PMMA has good impact properties. As the PMMA surface hardness is not high, easy to clean hair, low-impact resistance, molding defects and poor flow properties, PMMA modified one after another. Such as methyl methacrylate and styrene butadiene copolymer, PMMA and PC blends and so on. Super transparent PMMA material mainly used for mobile protection screen, the product is divided into a hardening coating, without curing the coating two. It features excellent light transmission rate, impurities, electrostatic protective film, the surface hardness after hardening up thick 5-6H above present especially recommended for hardening of the PMMA material, the domestic as health board.
