XLPE XLPO TPU TPE PUR PVC Masterbatch for Wires
XLPE Color Masterbatch for Wires
XLPE (Cross-Linked Polyethylene) color masterbatch is a concentrated mixture of pigments/dispersants within a specialized XLPE-compatible carrier resin. It's added during wire/cable extrusion to impart consistent, durable coloration to the insulation or jacketing layer. Key requirements include:
High Thermal Stability: Must withstand XLPE processing temperatures and the crosslinking step (often peroxide-induced or steam cure).
Excellent Dispersion: Ensures uniform color without defects impacting insulation integrity.
Compatibility: Carrier resin must fuse seamlessly with the base XLPE compound.
Electrical Properties: Must not significantly degrade XLPE's crucial dielectric strength and insulation resistance.
Light & Weather Fastness: Colors must resist fading from UV exposure and environmental factors over the cable's lifespan. Masterbatches ensure identification, branding, and safety compliance (e.g., phase coding).

XLPO Color Masterbatch for Wires
XLPO (Cross-Linked Polyolefin) color masterbatch delivers vivid, durable coloration for wires and cables insulated with cross-linked polyolefin blends. Added during extrusion, it must withstand high processing and crosslinking temperatures (commonly peroxide-induced or silane-cured) without degradation. Essential properties include:
Exceptional Thermal Stability: Resists temperatures exceeding those of standard XLPE, often >250°C during curing/service.
Perfect Compatibility & Fusion: Seamlessly integrates with diverse XLPO base resins (PE, EVA, EBA blends).
Superior Dispersion: Ensures flawless color uniformity without compromising insulation integrity.
Electrical Integrity: Must not degrade the XLPO's critical dielectric strength and insulation resistance.
Long-Term Durability: Provides UV, weather, and chemical resistance for harsh environments like automotive (EV cables) or industrial applications.
