Use range:

Advanced plastic colorants belong to the category of oil-soluble dyes and can be dissolved in organic solvents. It can be used in a single color, and can be used after being formulated into various tones in a certain proportion according to the needs. They are all suitable for the dyeing of the following plastics.

(PS) Polystyrene (SB) Styrene-butadiene copolymer

(HIPS) high impact polystyrene (AS) acrylonitrile-styrene copolymer

(PC) Polycarbonate (ABS) Acrylonitrile-butadiene-styrene copolymer

(UPVC) Rigid polyvinyl chloride (372) Styrene-methacrylic acid copolymer

(PMMA) polymethyl methacrylate (CA) cellulose acetate

(SAN) Styrene-acrylonitrile copolymer (CP) Acrylic cellulose

Dyestuff application:

When coloring various plastics, a certain proportion can be directly added to the plastic and mixed evenly to be pre-molded or molded, and the color density can be adjusted according to the required amount. Dyes can obtain bright and transparent colors in transparent and clean resins. If used in combination with appropriate amounts of titanium dioxide and dyes, translucent or opaque colors can be obtained. The dosage can be negotiated according to needs, the general dosage for transparent tones is 0.02%-0.05%, and the normal dosage for opaque tones is about 0.1%.
