Applications

Presol Dyes are comprised with a wide rage of polymer soluble dyes which can be used for coloring a wide variety of plastics. They are normally used via masterbatches and add into fiber, film and other plastic products.

When using Presol Dyes into engineering plastics with strict processing requirements, such as ABS, PC, PMMA, PA, only specific products are recommended.

When using Presol Dyes into thermo-plastics, we suggest to mix and disperse the dyes sufficiently together with the right processing temperature to achieve better dissolution. In particular, when using high melting point products, such as Presol R.EG (Solven Red 135), a full dispersion and suitable processing temperature will contribute to a better coloration.

High performance Presol Dyes are complaint with the global regulations in below applications:

●  Food packaging.

●  Food-contacted application.

●  Plastic toys.
