PU Pigment Dispersions

Product Overview

Fibreroot Pigment – PU Pigment Dispersions
Advanced reactive pigment pastes and dispersions specifically formulated for polyurethane systems. Designed for deep color, consistency, and full integration into both flexible and rigid PU formulations used in foams, molded parts, coatings, adhesives, and specialty applications.

Core Product Variants

• Fibreroot PU Reactive Pigment Paste
  (PU Colorants Paste: high-strength paste for dosing machines; usage 1.0–1.5 wt%)

• Fibreroot Polyurethane Pigment Dispersions
  (Finely dispersed pigment pastes across 15–30% loading concentration)

• Fibreroot Polymeric Colorant
  (100% liquid polyol-soluble colorants for inline blending and superior stability)
  
  

Key Features

• Reactive, polyol‑carrier paste that becomes a full part of the PU matrix—no binder residues or migration.

• Low-viscosity pastes ideal for automated dosing—even at low usage rates (1–1.5 wt%).

• Wide pigment load availability (15–30 % pigment in carrier) for intense shades and deep hues with controlled viscosity.

• Phthalate-free, non-yellowing white options with UV resistance, compliant with EU REACH—great for footwear/ consumer safety products.

• Melamine-based fire‑retardant/acoustic options available for specialty PU applications.

• High jet-black formulations for deep blacks using reactive polyol-compatible carrier systems.

• Broad shade spectrum beyond basics—specialty colors are readily customizable and stable.

• Heat, light, and chemical stability—formulated for long-lasting UV resistance without fogging.

• Consistent color & viscosity from batch to batch; avoids settling, separation or mechanical blockages.
  
  

Technical Parameters

• System Compatibility: Polyether and polyester polyol systems—depending on your existing PU formulations.

• Typical Pigment Loading: 1.0–1.5  wt% for solid shades—higher if opacity or effect is critical.

• Pigment Concentration in Paste: Around 15–30  % pigment loading for vivid, high-intensity shades.

• Form: Low-viscosity reactive paste or fully soluble liquid colorant (polymeric).

• Carrier: Reactive polyol-based—fully integrated into PU matrix without additive migration.

• Stability: Thermal, UV, and light stabilized; non-settling formulation ensures uniform dispersion in storage and processing.
  
  

Applications

• PU Foams: flexible, semi-rigid, integral-skin, rigid, and specialty foams for insulation, cushioning, packaging, and orthotics.

• Molded Parts: toys, grips, housings, and intricate cast or injection-molded components.

• Footwear & Apparel Components: vivid, safe color in midsoles, inserts, cushioning units.

• Adhesives, Coatings & Sealants: color-matched or transparent systems where clarity or branding matters.

• Marine, Automotive & Structural Parts: components for harsh UV or chemical exposure.
  
  

Storage & Shelf Life

• Storage Conditions: Keep sealed in cool, dry conditions—avoid heat and moisture.

• Shelf Life: At least 12 months when stored as recommended; longer when refrigerated or cool-stored.
  
  

NZ Market Fit

Why Fibreroot PU Pigment Dispersions are ideal for New Zealand:

• Polymer-reactive carriers ensure full integration—no phase separation in cooler climates or long delays typical of batch processing.

• Compliant with safety standards for footwear, toys, and consumer goods (phthalate-free, non-yellowing).

• Supports high-performance outdoor products (UV-, heat-stable formulations).

• Suitable across applications from marine-composite parts to building insulation foam, matching your existing product and client base.
