Is the polyurethane plastic made of transparent wrapped aluminum silk easy to yellow?

Answer:

If you want permanent resistance to yellowing, you can only use the aliphatic, but the price of this raw material is high.
Polyurethane TPU is a common problem with this yellowing, but if you add some anti UV agent during production, it can take a while to prevent yellowing, but it can not reach permanent yellowing resistance.
