JETEX KP-203 | Ultra-Clean Low-PAH Specialty Carbon Black for Plastics & Inks
JETEX KP-203 is a premium, high-purity specialty carbon black designed by Himadri Speciality Chemical Ltd. to deliver maximum opacity, UV protection, and color strength for plastic masterbatches and performance inks. Engineered to comply with strict low-PAH regulations, it features an ultra-clean profile with a low sieve residue ($\le 40\text{ ppm}$ at 325 mesh) that guarantees an exceptionally smooth surface finish and superior filterability. With a high iodine number ($121\text{ g/kg}$) and a high tinting strength ($111-116\%$), JETEX KP-203 is the premier choice for agricultural films, utility pipes, engineering plastics, and high-gloss newspaper printing inks.
Product Overview
JETEX KP-203 (marketed under the Kohlenstoff® product range) is an advanced, industrial-grade specialty carbon black explicitly developed by Himadri Speciality Chemical Ltd. for plastics compounding, extrusion, and high-speed ink applications. Engineered with a high surface area (I₂ No. $121\text{ g/kg}$) and optimized structural morphology, this pigment black provides outstanding covering power and a strong blue undertone.
A major regulatory and technical advantage of JETEX KP-203 is its strict compliance with international low-PAH (Polycyclic Aromatic Hydrocarbons) standards. This makes it a certified solution for components demanding premium cleanliness. Its minimal grit levels protect high-pressure melt filters during manufacturing and ensure a defect-free, ultra-smooth surface finish on finished extruded sheets, films, and molded components.
Certified Low-PAH Cleanliness: Formulated through clean furnace engineering to assist manufacturers in comfortably meeting strict global PAH safety regulations.
Elite Color Strength & Tinting: Delivers a superior tint profile ($111-116\%$) and exceptional color intensity, producing rich masstones and excellent jetness in plastics and inks.
Advanced UV & Weathering Shielding: Actively absorbs high-energy ultraviolet solar radiation, shielding host engineering plastics from structural degradation, chalking, and brittleness.
Excellent Filterability & Extrudability: Features a tightly controlled sieve residue ($\le 40\text{ ppm}$ on 325 mesh), reducing manufacturing screen changes and keeping thin-gauge films free from pinholes.
High Gloss for Ink Formulation: Imparts high-gloss values and clean dispersion characteristics, perfectly matching the flow criteria needed for premium newspaper printing inks.
Technical Thermoplastics & Films: High-pigment masterbatches for agricultural mulch films, silage wraps, and industrial sheets.
Infrastructure Piping: Durable general-purpose and engineering utility pipes requiring permanent UV defense.
Molded Consumer & Industrial Goods: Plastic enclosures and automotive trim parts requiring premium surface smoothness and high jetness.
Performance Inks: High-performance pigment black for high-gloss, high-speed newspaper printing and offset inks.
