Introduction :

Polymethyl methacrylate, which is abbreviated as PMMA, is a clear plastic, used as a shatterproof replacement for glass. On both sides of the Atlantic PMMA is also marketed as Plexiglas. PMMA is more than just plastic and paint. Often lubricating oils and hydraulic fluids tend to get really viscous and even gummy when they get really cold. This is a real pain when you're trying to operate heavy equipment in really cold weather. But when a little bit PMMA is dissolved in these oils and fluids, they don't get viscous in the cold, and machines can be operated down to -100 oC (-150 oF), that is, presuming the rest of the machine can take that kind of cold! PMMA is a vinyl polymer, made by free radical vinyl polymerization from the monomer methyl methacrylate.

Properties :

hardrigidtransparent (very clear to see through) softening point at 125 deg C tougher than polystyrene but less tough than ABS (acrylobutylstyrene) polymerabsorbs very little visible light but there is a 4% reflection at each polymer-air interface for normal incident light. PMMA is a polar material and has a rather high dielectric constant and power factor (what is a power factor??) - a good electrical insulator at low frequencies but less satisfactory at higher frequencies good water resistance PMMA prepared by free radical polymerization is amorphous and is therefore soluble in solvents with similar solubility parameters such as benzene, toluene, chloroform, methylene chloride, esters, ethyl acetate, and amyl acetate. PMMA has good resistance to alkalis (sodium hydroxide, etc.), aqueous inorganic salts (the Pacific Ocean) and dilute acids. PMMA has a better resistance to hydrolysis than PMA probably by virtue of the shielding of the methyl group. PMMA 's outstanding good outdoor weather resistance is remarkably superior to other thermoplastics. When heated about 200 deg C, decomposition becomes appreciable and at 350- 450 deg C, a nearly quantitative yield of monomer is readily obtained. Thus, the recovery of monomer from scrap is feasible. Because it's a thermoplastic, it can be molten and molded (at 100 to 150 deg C) into anything we want.

Processability :POF is strong and very difficult to bend. There is only a small loss even when bent to a 25mm radius. Therefore, it can be installed within walls or other narrow areas. It is also suitable for lighting in tight locations.   Installation work is extremely simple. There are several methods, but the one common for transmission is the Hot Plate method. In this method, it takes advantage of the fact that the material used is plastic, so that fiber ends are heated and softened, then pushed against a mirrored surface. The process is quick and can be repeated with very little deviation. Therefore, installation is simple even for those who have never handled optical fiber.   Normally, a 650nm (red) LED is used as the light source for POF optical transceiver modules. Since this is within the visible light spectrum, it acts as an eye safety feature because the user can easily tell when he/she is in danger of directly viewing the light beam. Also, since 650nm will be the wavelength used for a large number of DVD light sources, we can expect the cost to drop even further.   POF is not suitable for long-distance transmission. compared with quartz fiber, there is a large transmission loss. However home and office applications do not require transmission over great distances, having a need for ease-of-use, low cost, and stability instead. POF is best suited for use in these environments.   Since POF is strong against vibration and bending, in addition to its conventional uses in high-speed trains and automobiles it has also recently been applied to car networks inside the vehicle due to an increasing multimedia demand from drivers.   Since POF transmits very little infrared light, it can be used for cold lighting (lighting that do not produce heat), for semiconductor manufacturing equipment and the lighting displays of artwork.
