SOLVENT DYES

Az0-and Apthraquinone-dyes with good miscibility tovarious plastic materials, such as polyolefins/ps/ABS/PVC¡­¡­etc¡­This range isalso good for coloring purpose for petroleum products as well as for oil &fat dyeing.

Solubility Test:
(1)Dissolve 20gm of Dye in 40ml of solvent stir Thoroughly seal the containerTightly and left over night.
(2)Stir the above Sample weight filter paper accurately before filtering thesample. Then put the residue and filter paper inside A thermostate with 50temperature Until all the liquid evapavated.
(3)Weight the residue(X) Total weight-weight of filter paper).

·        Determine the Solubility by calculation:

·        20 40 X 1000=Solubility (gm/l)

Fastness:

·        (1)Light resistance:Used standard BlueScale as comparsion standard

·        (2)Heat Resistance:Automatic ConstantTemperature Dryer at 180°C for 10 hours.

·        (3)Acid Resistance:immerse in 1% H2SO4solution for 24 hours.

·        (4)Alkali Resislance:Immerse in 1% NaOHSolution for 24 hours.

·        (5)Standard symbols for test: A:good B:fair C:Poor

1.BRIEF INTRODUCTION

Higher plastic colorant are most suitable for variousplastic materials coloring, with greater color strength, better fastness toheat, light, acid and alkali. This range is generally used in coloring domesticplastic materials, cop tube materials, fat dyeing, lacquers, inks and masterbatches dyeing. Some of them are suitable for dyeing chemicals fibre, such asdacron, nylon and cellulose acetate fibre.

2.APPLICATION

Hight plastic colorant are solvent dyes with goodsolubility and miscibility in organic solvents. This range can be used in thefollowing materials alone as well as mixed in proportion:

·        (PS) Polystrene

·        (HIPS) High impace polystyrent

·        (PC) Polycarbonate

·        (UPVC) Rigid poly

·        (PMMA) Polymethyl methacrylate

·        (SAN) Styrene-acrylonitrile copolymer

·        (SB) Styrene-butadiene copolymer

·        (AS) Acrylonitrile-stryrene copolymer

·        (ABS) Scrylonitrile-butadiene-styrenecopolymer

·        (372) Styrene methyl acrylic acidcopolymer

·        (CA) Cellulose acetate

·        (CP) Cellulose propylene

3.USAGE

The dye is dissolved in plastic inmolecular-distribution. Before molding or preplasticizing, add dyes intoplastic materials in proportion and stir thoroughly. The shade can be adjustedin demand. You can obtain transparency color in clear resin, or un-transparencycolor with titanium pigment. Use level:

·        Transparency color around 0.02%-0.05%

·        Un-transparency color around 0.1%
