Product Name：polycarbonated Molecular format：C31H32O7 CAS No：25037-45-0 Product molecular structure： Chemical Properties:  Polycarbonate is an amorphous, tasteless, odorless, non-toxic transparent thermoplastic polymer, has excellent mechanical, thermal and electrical properties, especially impact resistance, good toughness, creep is small, the product size is stable. Its notched impact strength of 44kj / mz, tensile strength > 60MPa. polycarbonate heat resistance is good, can be used for a long time at - 60 ~ 120 ℃, heat deflection temperature 130 ~ 140 ℃, glass transition temperature of 145 ~ 150 ℃, no obvious melting point, in 220 ~ 230 ℃ is molten state. Thermal decomposition temperature > 310 ℃. Due to the rigidity of the molecular chain, its melt viscosity is much higher than that of general thermoplastics. Application: Polycarbonates are plastics widely used in modern industry having good temperature and impact resistance. This plastic is particularly good to work with more conventional definition techniques (injection molding, extrusion into tubes or cylinders and thermoforming). It is also used when optical transparency is needed, having more than 80% transmission up to the 1560-nm range (short wave infrared range). It has moderated chemical resistance properties, being chemically resistant to diluted acids and alcohols. It is poorly resistant against ketones, halogens, and concentrated acids. The major disadvantage associated with polycarbonates is the low glass transition temperature (Tg> 40°C), but it is still largely used as low-cost material in microfluidic systems and also as a sacrificial layer.
