Pigment Yellow 14, Fast Yellow 2GS
Pigment Yellow 14 is a semi-opaque mid green shade pigment yellow, an economical choice. It’s processing temperature should below 180℃, suitable for indoor usage.
Application of P.Y.14 in plastics varies according to the region. It is more important in the USA, Japan and China where it is used in polyolefins than in other countries.
P.Y.14 is also used for spin dyeing viscose rayon and viscose cellulose, and it is an especially important product for the mass coloration of viscose sponges.
When P.Y.14 is worked into plasticized PVC and polyolefins, there is a certain concentration threshold beyond which the pigment will bloom.
