1 Why polycarbonate is the good choice for LED lens?
Compared with glass or PMMA, polycarbonate resins have the better property of impact resistance.
Furthermore, polycarbonate virgins can be modified with the flame retardant UL V0@0.75mm,5VA@3mm.
2 What properties are required for the PC in Led lens?
According to the market demand, Dongguan Forever Co.,Ltd has manufactured the polycarbonate(pc)
compound, which easy to process, high flow(5-60 MFI 300℃,1.2KG), nice optical clarity especially for the
thick lens,outdoor usage with the UL746C-F1 certficate
3 Who is the pioneer in the worldwide?
