PMMA is the best polyme tanspaent mateial at pesent, and its visible light tansmittance is 92%, which is [1] highe than that of glass.1. ultaviolet light: quatz can be completely ultaviolet light, but the pice is high, odinay glass can only pass though 0.6% ultaviolet ay, but PMMA can pass though 73%. PMMA can't filte out ultaviolet (UV). Ultaviolet light penetates PMMA, and pat of the manufactue [2] is coated on the suface of the PMMA to incease the effect and popeties of the UV light. On the othe hand, PMMA has bette stability than polycabonate in the condition of ultaviolet light iadiation.2. infaed: PMMA allows infaed ays less than 2800nm wavelengths to pass though. Longe wavelengths of IR, less than 25000nm, ae basically blocked. Thee is a special coloed PMMA that allows a specific wavelength of IR to pass though and block visible light, (used fo emote contol o heat, etc.).The POM enhanced POMThe main einfocement mateials ae glass fibe, glass ball o cabon fibe, and glass fibe is most commonly used. The mechanical popeties of the einfoced glass can be inceased by 2~3 times and the hot defomation tempeatue is inceased by 50 degees o moe.The high oil POMAdding gaphite, F4, molybdenum disulfide, lubicating oil and low molecula weight PE to POM can impove its lubication pefomance. Fo example, adding 5 copies of F4 in POM can educe the fiction facto by 60%, and incease the wea esistance by 1~2 times. In addition, the addition of liquid lubicating oil in POM can geatly impove the wea esistance and the limit of PV. In ode to impove the dispesing effect of oil, the oil absoption caie, such as cabon black, baium hydoxide, and ethylene popylene ubbe, should be added. The fiction of adding 5% oil POM is inceased by 72%, and the limit PV can each 3.9MPa m/s (pue POM is 0.213MPa m/s), which is 3~20 times that of othe engineeing plastics.PPO B has good electical popeties in a wide ange of tempeatue and fequency. It has no hydolysis and shinkage, and has no self extinguishment. It is esistant to inoganic acid, alkali, aomatic hydocabon, halogenated hydocabon and oil. It is pone to swelling o stess cacking. C, it has the advantages of lage igidity, high heat esistance, efactoy, high stength and so on. D and polyethe have the advantages of wea-esistant, non-toxic, and esistant to pollution. Dielectic constant and dielectic loss of E and PPO plastic mateials ae among the smallest vaieties in engineeing plastics. They ae hadly affected by tempeatue and humidity. They can be used in low, medium and high fequency electic fields. The load defomation tempeatue of F and PPO can each moe than 190 degees C, and the embittlement tempeatue is -170 C. G, its main shotcomings ae poo melt fluidity and difficult pocessing.。
