Pigment red 48:2 for Plastics

P.R.48:2 is also used in plastics, where it affords good tinctorial strength. Such colorations are heat stable up to 230°C for 5 minutes, but higher temperatures shift the color towards bluer, duller shades. At higher temperature, on the other hand, more reduced colorations (1/9 SD) shift the shade to yellower and cleaner hues. P.R.48:2 is used to an appreciable extent in LDPE, in which it is more lightfast than corresponding P.R.48:1 samples: the difference is about 2 1/2 steps on the Blue Scale. Incorporated in plasticized PVC, P.R.48:2 is not entirely 2.7.2 BONA Pigment Lakes 327 bleed resistant. The pigment may be used in PP spin dyeing only if polymers with a low melting point are used. In order to ensure sufficient light fastness, the pigment is used to advantage in deep shades, i.e., at high concentration.
