Antioxidant, UV Stabilizer, Flame Retardant for PA
PA is an abbreviation of polyamide which is a semi-crystalline polymer. There are two types: those made of one basic material (e.g.PA 6) and those made of two basic materials (e.g. PA66). They can occur both naturally (e.g. wool and silk) and synthetically (e.g. nylon).

Organic Pigment for PA
Pigments that are targeted for polyamide spin dyeing, apart from being extremely heat stable, must also be chemically fast to the highly reducing medium of the PA melt. Spinning temperatures are between 250 and 290°C, depending on the type of polyamide. As with polyester extrusion, only very few polycyclic pigments are suitable for this purpose. There are no organic yellow pigments which satisfy the specifications. Pigment preparations are also available for this purpose.
Pigment suited for PA listed as below;
Pigment orange 68.
Pigment red 149, Pigment red 177, Pigment red 178, Pigment red 179, Pigment red 202.
Pigment violet 23, Pigment violet 29.
Pigment blue 60, Pigment blue 15:3.
Dyes for PA
Solvent yellow 21, Solvent Orange 63, Solvent red 122, Solvent red 214, Solvent blue 70, Solvent blue 132 are frequently used in coloring PA.
