Why can PC lampshade crack

Many LED fluorescent lamp manufacturers in the production process, and fluorescent lamp aging in the process of use there will be cracks. Now I will analyze the cause of this crack. For your reference. PC material originally for polymer, its toughness is often good, in the normal range of material characteristics, the proportion of PC molecule cracking is less, that is to say, the cracking phenomenon of PC material is smaller. So why now the PC lampshade will appear to have cracking? The main reason is that the structure of PC molecular chain is damaged and the molecular chain is disconnected. Resulting in product cracking or surface cracks. Factors affecting the structure of molecular chains

PC lamp shade is made of PC (polycarbonate) as raw materials of light bulbs, LED lamps, LED fluorescent lamps, car lights and lamp shell series of lamp shade.

Polycarbonate is A thermoplastic resin with - [O-R-O-CO] - chain in the main chain of the molecule, according to the different ester groups in the molecular structure can be divided into aliphatic, aliphatic, aliphatic aromatic type, which has practical value is aromatic polycarbonate, and to bisphenol A type polycarbonate is the most important, the molecular weight is usually 3-100,000.
