Will pigment yellow 180 migrate in LDPE

Today, we will answer the question of whether Pigment Yellow 180 migrates in LDPE.

First, let me introduce the characteristics of Pigment Yellow 180. It is an organic yellow pigment with good heat resistance, solvent resistance, and chemical resistance, medium acid and alkali resistance, poor low-temperature resistance, easy to dissolve in water, soluble in alcohol, ketone, benzene and other organic solvents, not soluble in oil.

So, will Pigment Yellow 180 migrate in LDPE? The answer is no migration. Pigment Yellow 180 has excellent resistance to migration, and it basically does not occur in all materials. Under normal circumstances, if the pigment is wrapped by plastic, it will not migrate, and the pigment content in plastic is generally in the range of thousands to tens of thousands of parts per million. There is one exception, which is making high concentration color masterbatches. Due to the high pigment content, usually more than 10%, the pigment-resin ratio is out of balance, and titanium white powder is usually added. Because titanium white powder also adsorbs resin, it affects the migration performance of pigments, and there may be a phenomenon of pigment migration in the masterbatch. However, in general, when injection molding with masterbatch, the pigment will not migrate.

That's all for the answer to whether Pigment Yellow 180 migrates in LDPE. If you have any other questions, please leave us a message, and we will reply to you as soon as possible. Thank you for watching!
