Solvent dyes and pigments for Polyester, Fiber, Polymers, Engineering Plastics etc.:
SUBH CHEM has a scope of supply which very few Solvent Dyes and Pigment supplier can claim. The range covers one of the widest numbers of Solvent Dyes and Pigments. Our products are tailored to confirm the International standards and specifications.
The Solvent Dyes mentioned in this series disperse and dissolve easily in the polymer melt. This property of Solvent Dyes is to give brilliant coloration with sparkling transparency. For opaque plastics attractive pastel shades can be obtained with the use of Titanium dioxide. They can also be used in combination with pigment colors either as shading components or as major ingredients in a mixture for getting intensity and translucence often not obtainable by use of insoluble organic pigments alone. These developed tailor-made combinations give economic and attractive shades.
Solvent Dyes in this series are divided as:
Series (I) best suited for Engineering plastics and Series (II) best suited for Polyolefin.
These dyes are heat stable at customary processing temperatures which are higher than that of Polyolefin. These dyes do not sublime from polymer melt during processing cycles used to prepare polymer / master batch blends for final processing.
Light fastness of these polymer soluble dyes are generally excellent in strong and transparent shades. These dyes are suitable for Engineering plastic such as Polystyrene, HIPS, ABS, SAN, Polycarbonate, PET etc.
For specific use of these dyes in food packaging analysis as required can be arranged (with suitable arrangements).
Dyes under this series are not recommended for Polyolefin as migration of color from the...

Polyolefin find a number of usages due to low cost, good process ability and overall good polymer properties.
Polyolefin are all highly crystalline polymers. Coloration of these polymers becomes very difficult due to high crystalline and lack of any reactive sites. Pigments are widely used for coloration of these polymers but they have some limitation due to insolubility and poor dispensability which leads to non-uniform coloration.
SUBH CHEM supply number of solvent dyes for the coloration of Polyolefin, which due to solubility and high affinity for polymers gives stronger, brighter and uniform shades then pigment. Fastness properties of these dyes are also excellent.
