Polycarbonate Resins For Outdoor Use UL746C F1-Forever Plastics
Dongguan Forever Co.,Ltd has developed the Polycarbonate PC resins or granules for Optical lens, ultra-thin light guide.
What properties or standards of of Polycarbonate for Outdoor Use?
For the plastics parts made of polycarbonate granules or resins, the most popular standard is UL746C-F1/F2.
UL746C requires two methods of testing:
<1> The samples are exposed to carbon weatherometer for 720hours or xenon-arc weatherometer for 1000hours.
The flammability level will keep the same,while the mechanical properties will keep more than 70% compared the
specimen
<2> The samples are immersed in water for 7 days at the temperature of 70℃. The test specimen must keep more
than 50% of the original properties like the tensile strength, the flexual modulus.....
Dongguan Forever Co.,Ltd has produced this modified polycarbonate for catering for the market high quality requirements.
