What's the difference between a glass cap for a bulb and a PC hood?
Surface hardnessPC biggest weakness is surface hardness, PC although resistance to impact, smashing not broken, but after all is plastic, surface hardness value is not high, easy to scratch, easy to scratch.While glass is easy to break, not shock, but the surface hardness is high, it is not easy to scratch the surface!Other weather resistant, temperature resistant supplementsPC cover, in processing, plus UV agent
Transparency comparisonPC transparency is 90%, glass transparency is 95%, but the naked eye does not seem to distinguish between too big, because it is 5%, ha ha,Only several meters can be measured by instruments.
ProcessabilityMachinable, blister, special-shaped processing PC easier.
Weight comparisonPC specific gravity 1.2,The proportion of glass (usually glass) is 2.5,That is to say, PC is lighter in weight than glass.
1, impact strength comparisonPC and glass is the biggest difference resistance shock, PC is transparent plastic, the most resistant to impact, smashing not broken.Similarly, PC is 200-300 times the impact resistance of glass. PC is 30-50 times the impact strength of PMMA acrylic.
