Does polycarbonate yellow with age and ultraviolet ray exposure?
Yes, polycarbonate can yellow with age and exposure to ultraviolet (UV) rays. This degradation occurs due to the breakdown of the polymer structure when exposed to UV radiation, leading to discoloration and loss of clarity. To mitigate this effect, many manufacturers add UV stabilizers to polycarbonate products, which can help prolong their lifespan and maintain transparency. However, even with these additives, some yellowing may still occur over time.
Does lexan yellow with age?
Lexan is a name brand of polycarbonate plastic. Sort of like Xerox has come to mean making a copy on a photocopier. Polycarbonate will lose many beneficial characteristics if left in sunlight extensively. It has a blue tint that would tend to cancel some yellowing effects of sunlight but will turn yellow if left in sunlight over a long period of time. Other types of plastics turn yellow in sunlight as well. No sunlight, no yellow. It also becomes brittle and generally weaker over time when exposed to sunlight. This type of plastic has been used in bullet proofing cars. However, over a period of time in sunlight, the plastic must be replaced if it is to continue stopping bullets. I saw a .44 magnum cal. bullet imbedded in a 1 inch thick piece of poly-carbonate years ago. The inside surface had a slight dimple. Polycarbonate does not fracture or crack if in good condition (no sunlight).

Will polyurethane yellow over time?
Yes, polyurethane can yellow over time due to exposure to light and heat.
Does polyurethane yellow over time?
Yes, polyurethane can yellow over time due to exposure to light and heat.
Does urethane yellow over time?
Yes, urethane can yellow over time due to exposure to light and air.
Do clear cases turn yellow?
Yes, clear cases can turn yellow over time due to exposure to UV light, heat, and oils from skin. This discoloration is often more pronounced in cheaper materials like polycarbonate and TPU. Maintaining the case by cleaning it regularly and avoiding prolonged exposure to sunlight can help minimize yellowing.
Does polyurethane turn yellow over time?
Yes, polyurethane can turn yellow over time due to exposure to light and oxygen.

Does oil-based polyurethane yellow over time?
Yes, oil-based polyurethane can yellow over time due to exposure to light and air.
Does silver turn yellow over time?
Yes, silver can tarnish and turn yellow over time due to exposure to air and certain chemicals.
Which is better glass or polycarbonate?
Whether glass or polycarbonate is better depends on the application, as each has its strengths and weaknesses: ✅ Glass – Best for Clarity & Scratch Resistance Pros: Excellent optical clarity (crystal clear) Highly scratch-resistant UV stable (won’t yellow over time) More rigid and aesthetically refined Cons: Brittle – can shatter or crack on impact Heavier than polycarbonate Best for: Windows, aquariums, high-end displays, and places where clarity and scratch resistance matter most. ✅ Polycarbonate – Best for Impact Resistance & Flexibility Pros: Extremely impact-resistant (250x stronger than glass) Lightweight Shatterproof Easy to cut and shape Cons: Prone to scratching unless coated Can yellow over time if not UV protected Best for: Safety glazing, eyewear lenses, riot shields, greenhouse panels, and areas where durability and safety are key.
