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).

Non-halogen Flame Retardant For PA

For halogen-free flame retardant for PA,  aluminum diethyl phosphinate ADP is recommended. MCA can also be used in polyamide as flame retardant.

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.
