Polymer Additives

ROYALE BLACK® PF606 specialty carbon black provides excellent jetness and blue under tone for fiber applications. It is designed with a high level of cleanliness, to reduce fiber breakage and increases spin-pack life that improved productivity.

ROYALE BLACK® PF401 is a high end specialty black in our product range. It provides significant advantages to fine denier polyester fibre spinner and masterbatch producers. Its ultra-physical cleanliness increases melt fibre life by reducing plugging resulting in low production cost of fibre manufacturing.

ROYALE BLACK® PC501 is a cost-effective black for semicon applications. It is an easy processing, ultra clean conductive black designed for use in semi conductive compound for medium voltage power transmission cable application. ROYALE BLACK® PC501 contains very low sulphur and low ash which improves cable life. It provides good surface smoothness and strippability in the semiconductive compound. Very low sieve residue and ash content of ROYALE BLACK® PC501 prevent washout of any ionisable material which results in initiation of electrical degradation site. ROYALE BLACK® PC501 has very low sulphur content so that it does not react with polymers in the presence of electrical stresses, thereby increasing cable life.
