Antioxidant, UV Stabilizer, Flame Retardant, Heat Stabilizer for Polyamide(Nylon)

PA is an abbreviation of polyamide which is a semi-crystalline polymer, also known as Nylon. 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).

1. Flame Retardant For Polyamide(Nylon)

1.1 non halogen flame retardant for polyamide(nylon)

For halogen-free flame retardant for PA,  aluminum diethyl phosphinate ADP and MPP is recommended.  MCA can also be used in non-glass fiber reinforced polyamide as a flame retardant.

1.2 flame retardant for polyamide(nylon)

Brominated flame retardant and antimony trioxide are used together as halogen flame retardants for polyamide(Nylon).

3. Heat Stabilizer for Polyamide(Nylon)

There are many types of heat stabilizers that can be used in polyamide, amine, phenolic, organic and inorganic phosphites, copper salt-based, the iodide. They are used are blends to achieve different performances in polyamide. Baoxu chemical offer bruggolen H10 same performance at half dosage. We also offer iodide group heat stabilizers.

5. Organic Pigment for Polyamide(Nylon)

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 that satisfy the specifications. Pigment preparations are also available for this purpose.

Pigment suited for PA is listed as below;

Pigment Yellow 110, Pigment Yellow 147, Pigment Yellow 148, Pigment yellow 150, Pigment yellow 187,  Pigment yellow 192.

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.

6. Solvent Dyes for Polyamide(Nylon)

Solvent yellow 21, Solvent Orange 63, Solvent red 122, Solvent red 214, Solvent blue 70, Solvent blue 132 are frequently used in coloring polyamide.
