polymer used in Crucial's Cream, milk, and milk 2%?

Does anyone know what type of plastic Crucial’s Cream, milk, and milk 2% are made out of? I’m not sure how to contact them because their website is down, but I need to know what the chemical composition of the polymer is they use to make the yoyos listed above. Any ideas?


It is just delrin

Polyoxymethylene, DuPont’s name for it is Delrin. It is generically known as acetal copolymer. Delrin can be purchased in black or white, but acetal copolymer can be purchased in a variety of colors.

Thanks! I’m doing a paper for material science, this will help a lot.
