Polystyrene KeyPlast®: A spectrum of bright colorants for plastics

Commonly used in packaging, disposable utensils, appliances and children’s pool toys, polystyrene, ABS, and SAN are highly versatile polymers. Milliken produces a wide range of colorants suitable for these polymers that meet your economic and performance requirements. Most dyes are extremely compatible with general-purpose, medium and high-impact grades of polystyrene. SAN is also easily colored with dyes but higher processing temperatures and higher physical demands may make some dyes less suitable. ABS is one of the most difficult styrenic polymers to color.
