dammedia.osram.infoFigure 3 illustrates the concept of thermal oxidation, free radical formation and shows images of a thermoplastic-based housing material before and after discoloration occurs. Silicone-based housing materials have a relatively high thermal stability. This broader temperature stability range makes silicone a suitable candidate for LED housings.
