Overview
White
Masterbatch is a concentrated mixture of high-quality pigments dispersed in a
polymer carrier resin. It is widely used to impart brilliant whiteness,
opacity, and superior coverage to plastics. With carefully engineered
dispersion and optimized pigment loading, white masterbatches provide
consistent color strength, UV protection, and processing stability across
diverse applications.
Applications
- Packaging:
Films, bottles, and containers for food, pharma, and consumer goods.
- Injection
& Blow Molding: Household items, cosmetics packaging, industrial
parts.
- Extrusion:
Pipes, sheets, profiles, and laminates.
- Fibers
& Nonwovens: Hygiene products, textiles, and agricultural covers.
- Engineering
Plastics: Automotive, electronics, and durable consumer goods.
Processing Techniques
- Injection
Molding – for precision parts and consumer products.
- Blow
Molding – bottles, containers, and hollow articles.
- Film
Extrusion (Blown & Cast) – flexible packaging, lamination films.
- Sheet
& Profile Extrusion – rigid sheets, thermoformed articles.
- Fiber
Spinning – nonwoven fabrics and textile applications.
Physical & Chemical Properties
- Pigment
Content: Optimum for grade for superior opacity and weather resistance
- Carrier
Resin: PE, PP, PS, PET or universal carriers for compatibility with
end-use polymers.
- Appearance:
Free-flowing white granules or pellets.
- Particle
Size: Nano to micron level, optimized for dispersion and opacity.
- Weatherability:
High resistance to UV degradation when rutile TiO₂ is used.
- Thermal
Stability: Designed to withstand polymer processing temperatures (up
to 300 °C, depending on grade).
- Lightfastness:
Excellent—ensures long-lasting whiteness and color consistency.
Sustainability
- Optimized
loading reduces raw material consumption while achieving maximum
opacity.
- Carrier
resin compatibility ensures recyclability with the base polymer like
PE/PP/PET/ABS/PBT/POM/PMMA/EVA/SAN
- Heavy-metal
free formulations comply with food-contact and global safety
standards.
- Energy-efficient
dispersion lowers processing waste and improves productivity.
- Can
be integrated into recyclable and bio-based polymer systems,
supporting circular economy goals.
