Category
Engineered for recycled streams
Recycled flakes carry hidden moisture — the root cause of bubbles, silver streaks and brittle weld lines. Our functional additives chemically neutralize these defects at the extrusion stage.
Moisture Elimination
CaO-driven chemistry binds free water during melt — no pre-drying loops, no pinholes.
Recycled Compatibility
Optimized for rPP, rHDPE, rLDPE and high mineral-filler compounds up to 80% loading.
Processing Stability
Smooth melt flow, lower torque, fewer line stops — direct yield uplift on extruders.
Quality Assurance
Batch-tested CaO content, certificate of analysis on every shipment.
White Desiccant MasterbatchAnti-Moisture Additive
AZ-DESI-CAO85
White pellets — uniform geometry, low dust, vacuum-sealed moisture barrier packaging.
An advanced, high-efficiency calcium oxide (CaO) based masterbatch specifically engineered to eliminate moisture, porosity, and silver streaks in recycled plastic processing. Ideal for recycled PP, PE, and high-mineral filler compounding.
Key Benefits
Active Moisture Elimination
Chemically binds with moisture during extrusion to prevent bubbles and pinholes.
Processing Optimization
Improves surface finish and mechanical properties of recycled resins.
High Compatibility
Perfectly compatible with Polyolefin matrices (PP / HDPE / LDPE).
01
Dose at hopper
Blend 1–3% with recycled flake feed.
02
Melt phase reaction
CaO + H₂O → Ca(OH)₂, irreversibly bound.
03
Defect-free melt
No vapor, no bubbles, no silver streaks.
04
Consistent finish
Glossy surface, stable mechanicals.
White Masterbatch (50% TiO₂)Grade F2145
ALLZONE F2145
Consistent dispersion · High opacity · Thermal stability up to 280°C.
ALLZONE F2145 is a high-performance White Masterbatch formulated with a 50% Titanium Dioxide (TiO₂) content concentrated in a Polypropylene (PP) carrier resin. Designed for high-specification industrial applications, it provides consistent dispersion, high opacity, and stable thermal performance during processing.
