Pigment Red 53:1 For plastics P.R.53:1 is used for its excellent heat stability as a colorant for plastics. 1/3 SD samples in HDPE withstand exposure to about 260°C for 5 minutes. Under common processing conditions, up to 260°C, P.R.53:1 has practically no effect on the shrinkage of injection-molded polyolefins. Its lightfastness in PE is approximately between step 3 and step 1 on the Blue Scale, depending on the depth of shade and on the pigment concentration. P.R.53:1 is also very strong in PVC. It is not very lightfast, but a number of disposable articles are colored to advantage with P.R.53:1. However, it has a poor fastness to bleeding.
