Polycarbonate(PC), is a comprehensive engineering plastic with good performance, also known as transparent metal.PC has good impact strength and mechanical properties, a high degree of dimensional stability and resistance to high and low temperatures, electrical insulation and excellent optical properties.
ØWhat are the main applications of PC materials?
Electronics
PC materials are mainly used for the production of electronic product housings, display protection boards and optical lenses. Because PC has the advantages of high strength and impact resistance, it can effectively protect the internal circuit boards of electronic products without affecting the signal transmission and display effect.
Electrical field
PC materials are used in electrical switches, sockets and other electrical accessories due to their excellent insulating properties and high temperature resistance.
Automotive industry
PC materials are increasingly used in automotive interior and exterior parts. Usually used in automotive bumpers, lights, instrument panels, door handles and other components, PC in addition to high strength and wear resistance, but also to enhance the overall comfort and aesthetics of the car.
Construction material
Because of its excellent transparency, PC material is particularly suitable for use as sunshade, sound insulation boards and other building materials to enhance the lighting effect and comfort of the building.
Medical Devices
Due to its excellent corrosion resistance and high temperature resistance, PC is particularly suitable for use as a housing material for surgical instruments, medical instruments and equipment.

ØHow to get high-quality transparent PC？
Although PC has excellent mechanical and optical properties, its light resistance still needs to be improved. When PC long-term exposures to UV light, it will turn yellow, even degradation and brittle. This is mainly because it will start photooxygen aging reaction, when PC materials are subjected to heat, oxygen and light at the same time.
By adding UV absorbers can block the sensitive UV band of PC materials, thus reducing the speed of its light aging reaction, in addition, if used in combination with light stabilizers and antioxidants, it will further prolong the service life of products, so as to avoid the problems of yellowing and embrittlement.
Below additives are especially suitable for PC:
OMNISTAB UV360 is especially suitable for transparent PC materials, it has better thermo- stability during process, and could highly absorber the UVA band. UV360 can also be used as an eco-friendly alternative to the UV326.
OMNISTAB UV1164 is a kind of high molecular weight UV absorber. It has good thermal stability and low volatility during processing and using. UV1164 has good compatibility with most polymers, like PA, PC, PET, olefin, PMMA, etc..
OMNISTAB LS944 is a kind of HALS which could improve the light stability of polymers in long term.
OMNISTAB AN1098 gives the PC resin excellent processing stability and long-term thermal stability.
OMNISTAB AN9128 is usually used together with AN1098, which provides the synergistic effect.
