1. Product Introduction:
The colorants for high-grade plastic and polyester before spinning were researched and developed by experts who are rich-experienced in the development of oil-soluble dyes after many years efforts, which provide the systemic chromatogram for increasingly developing plastic industry to get all kinds of satisfying color tone by mutual matching, to make your products more colorful and more popular in the market.
The colorants for high-grade plastic and polyester before spinning are ideal colorant for all kinds of plastic and polyester fibre. They are of strong coloring power, excellent fastness to heat and light, good resistance to acid and alkali, brilliant color. Now, they are widely used in daily plastic, organic glass, PVC packing materials, decoration materials, pen making materials, telecommunication materials, yarn cop materials, industrial grease, paint, ink, colorant, etc. Some kinds are applicable for coloring and die-spinning of chemical fibre, terylene, nylon and acetate fibre.
2. The Range of Use:
The colorants for high-grade plastic and polyester before spinning belong to oil-soluble dyes, soluble in organic solvent. They can be used by monochrome or preparing into all kinds of color tones according to the requirements, applicable for dyeing of the following various plastic:(the resistance to discoloration is low in ABS)
| Polystyrene |
(PS) |
| High-impact Polystyrene |
(HIPS) |
| Polycarbonate |
(PC) |
| Polyvinyl Chloride |
(UPVC) |
| Polymethyl Methyl Acrylate |
(PMMA) |
| Styrene-acrylonitrile Copolymer |
(SAN) |
| Styrene-butadiene Copolymer |
(SB) |
| Acrylonitrile-styrene Copolymer |

3. Usage:
When the above dyes dissolve in molten mass of plastic, they distribute with certain molecularity. When coloring for all kinds of plastic, they can be directly added into plastic, to mix uniformly, then premoulding or moulding. The fresh and transparent color tone can be obtained if mixing dyes into transparent and clean resin. If used together with titanium pigment in appropriate amount, semitransparent or nontransparent color tone can be obtained. The usual use level is 0.02-0.05% for transparent color tone, while the usual use level is about 0.1% for nontransparent color tone.
