| Abstract: | The article introduced the special polybutylene terephthalate （PBT） compound for energy-saving lamp with anti-yellowing heat-resistant, the effect of composite stabilizers on the aging property of the energy-saving lamp PBT compound was studied. The result showed that the anti-yellowing affect of composite stabilizer 327/622 was better than 327/770, after 168 hours of artificial aging with xenon lamp test, the impact strength of anti-yellowing PBT Compound was above 90%, tensile strength was above 95% ,the chromatism △E was less than 5. And after 2000h of simulation indoor environmental equipment test, the chromatism was △E 4.72. |
