PC PC-110奇美---PC has good weather resistance and good stability to heat, heat radiation, air and ozone. The physical and mechanical properties of the products are almost unchanged after one year of outdoor exposure, but the PC will undergo photooxidation reaction under the action of ultr***iolet light near 290 nm and gradually aging. Photoaging begins with the yellowing of the surface, and gradually breaks the whole molecular chain, reduces the molecular weight, and finally cracks. Anti aging properties can be improved by adding ultr***iolet absorbers. PC (self extinguishing material) can burn in fire, but it will self extinguish after le***ing the fire source. If antimony trioxide flame retardant and phosphate plasticizer are added into it, the flame resistance of PC can be improved. Pure PC is colorless and transparent in appearance and has good tran***ittance. Its tran***ittance is related to the w***elength of light and the thickness of products. The tran***ittance of PC with thickness of 2mm is 90%. But it can't penetrate short w***e light below 290 × 10 - 3 nm
