I‘m not very good recognizing things that are look very closely related to each other, like this one. I was checking what materials I should get something I‘m buying and I want it to be polyester, but only a few other things come up, one of them being polystyrene and now I‘m kind of confused if polystyrene is the same thing as polyester, could yuo help me out?
No, they are both plastic polymers but they are different stuff. Polystyrene is commonly used in foam cups and insulation. Polyesters are a wide variety of plastic use or everything from fabric fibers to high grade lacquer finsishes.
I don't think they are the same. Chemically, I don't know if they are the same. I know polyester is used in cloth and polystyrene is more plastics and used to make toy models.
Leave it stock. The cold air intakes are a scam. They do not do anything except empty your pocket.
