MF001 PMMA colorless transparent glass-like, the proportion of 1.19, a lower surface hardness, hard objects can easily be scratched. Difficult to fire, but it can slow-burning, from the fire could continue burning, burning easily cracked, melted dripping, flame bright, blue bottom, white top, and send a strong floral smell rotting vegetables smell.
Performance
1. Transparency: MF001 PMMA are amorphous polymers, the internal molecular arrangement of the light will not interfere with access to its passage in various parts of the speed of light, which can all move the same speed (ie, a uniform refractive index), did not surrounded by scattered light will interfere with each other. Therefore, PMMA has good optical performance, high light transmission rate (90 ~ 92%, and wavelength). Extremely smooth surface film or bar, in the bend to a certain extent can also be injected into the light from one end of all progress in its internal reflection, the last shot from the other side, as if the water flow through the pipe as in (a certain curvature is the position after bending into the original position of the point of view, can not exceed 42 °; bending curved, the curved rod diameter or radius must be greater than three times the sheet thickness). But when sanding the surface of a part of the light can escape from here and show light. This feature can be used to create edge-emitting devices, surgical appliances.
2. Mechanical properties: MF001 PMMA mechanical strength than ordinary glass, more than 10 times higher, but compared to other plastics can only be considered moderate strength. The disadvantage is that the quality Qing Cui, easy to crack (or appear crazes), low surface hardness, easily scratched and dull; poor wear resistance, the coefficient of static friction between them is 0.8, the dynamic friction coefficient of steel is 0.45 ~ 0.50, so easy to scratch sanding.
3. Electrical properties: PMMA is a good electrical properties, especially in the low-frequency operating conditions. However, some of its unique electrical properties: the dielectric loss tangent with frequency increases. Influence of temperature and frequency dielectric constant, while the climate and humidity has little effect on the electrical properties. However, electrical properties than PE, PS arithmetic.
Features: excellent mobility, for large or thin molded products; acrylic grain processing generally can extrusion injection molding or compression molding, the molding temperature of about 170 ~ 240 ° C; PMMA is a colorless, transparent, transmission rate is the best plastic than glass high, the light through the range; reflectivity with the angle of incidence and change, there is light absorption is small, do total reflection. MF001 PMMA is light, tough, at room temperature under high mechanical strength, but also by the temperature effect is small, only when close to the softening point of strength and Tg only when a sharp decline; excellent surface gloss, tinting strength, good dimensional stability, but the surface trace of hardness and anti-poor, low impact strength, good electrical properties, but decreased with increasing frequency, low water absorption, resistance to water-soluble inorganic salts and some acid, and long-chain alkanes, ethers, fats, oils, not alkali; anti-aging, non-toxic, non-burning flame;
Uses: can be used for aviation, aerospace, automobile, ship bulletproof glass, window glass, instrument accessories, take cover, lights, light, optical instruments, such as glasses, magnifying glass and a variety of lenses. Construction materials such as color plates, high decorative materials, furniture, partitions. orthopedic medical devices such as artificial limbs, nose, eyes, medical light pipe, denture powder. stationery, household Lu, such as pen, drawing tools, teaching models, specimens, fixtures, buttons, hair clips, candy dish, etc..
