Key Features
100% Dye-Free Transparency: Unlike conventional transparent grey masterbatches that use acid dyes to achieve smoke-grey effects, PET-1000 delivers uniform translucent color using only nano carbon black pigment. This is the fundamental difference from market alternatives.
Superior Non-Migration: No acid dyes means zero migration into contents, no plate-out on preforms or molds, and no surface bloom over shelf life. Dye-based products inevitably migrate and stain; PET-1000 does not.
High Light Transmission: Preserves light transmission while delivering a premium smoke-grey tint, ideal for see-through packaging designs.
Weather Resistant: Stable outdoors with no fading or chalk-out under UV exposure.
Versatile Processing: Suitable for blow molding, injection molding, blown film and fiber spinning.
Performance & Compliance
Dye-Free & Non-Migrating
Pigment-only coloration. No acid dyes means no migration into contents, no plate-out on preforms or molds, and no surface bloom over shelf life.
n-Hexane & Oil Resistance
Withstands fatty and oily contents including edible oils, essential oils and lipid-based cosmetics without color bleed or loss of blackness.
No Exudate / Precipitation
Carrier and dispersant fully bound in the PET matrix; no specks, streaks or deposits during processing or after filling.
Long-Term Alcohol Resistance
Stable in prolonged contact with ethanol-based products — sanitizers, perfumes, colognes and alcohol-containing personal-care formulations.
Acid & Alkali Resistance (pH 3–9)
Performs across acidic beverages (pH 3) through alkaline cleaners and soaps (pH 9).
Weather & UV Resistance
Carbon black provides inherent UV screening, extending shelf life of light-sensitive contents while maintaining color outdoors.
