Masterbatches are precisely formulated, highly concentrated mixtures of pigments, additives, and a carrier polymer resin. Engineered for seamless integration into plastic processing, they deliver color, functionality, or enhanced material properties—without the complexities of handling solid additive powders or liquid chemicals.
By streamlining dosing and dispersion, masterbatches ensure consistent quality, cleaner processing, and greater efficiency across a wide range of polymer applications.
1. Color Masterbatches
Designed to deliver vibrant, consistent coloration across a wide range of plastic applications. Cosmo’s color masterbatches combine high-quality pigments with optimized carrier resins and stabilizers for lasting visual impact and performance.
White Masterbatch
- Formulated with high concentrations of Titanium Dioxide (TiO₂)
- Offers excellent opacity, brightness, and UV resistance
- Ideal for packaging, consumer goods, and applications demanding a pristine white finish
Black Masterbatch
- Based on carbon black for deep color and superior UV stability
- Provides durability in outdoor and high-performance environments
- Widely used in automotive parts, electronics, and outdoor equipment
Colored Masterbatches
- Available in a full spectrum: red, blue, green, yellow, orange, violet, brown, grey, and more
- Custom formulations balance pigment concentration, carrier resin, and UV stabilizers
- Tailored for industries such as toys, household items, industrial components, and decorative packaging
2. Additive Masterbatches
Formulated to enhance polymer functionality, durability, and aesthetics—beyond just color.
Processing & Performance Enhancers
- PPA (Polymer Processing Aid) – Improves melt flow, reduces die build-up, and stabilizes extrusion.
- Nucleating Agent – Accelerates crystallization, enhances stiffness, and shortens cycle time.
- Antioxidant Masterbatch – Prevents thermal and oxidative degradation during processing and use.
- Thermal Stabilizer – Maintains polymer integrity under high-temperature conditions.
Surface & Handling Modifiers
- Slip Masterbatch – Reduces surface friction for smoother film winding and handling.
- Antiblock Masterbatch – Prevents film sticking, improves clarity and separation.
- Antistat Masterbatch – Controls static charge and dust attraction in sensitive applications.
- Anti-Fog Masterbatch – Prevents condensation on packaging films, ideal for food and agriculture.
- Surfactant Masterbatch – Alters surface tension to improve wetting, spreading, and compatibility with coatings or inks—ideal for printing, lamination, and surface treatments.
- Breathable Compound Masterbatch – Enables controlled moisture vapor transmission while maintaining barrier properties. Used in hygiene products, medical textiles, and agricultural films, it allows breathability without compromising structural integrity.
Durability & Protection Additives
- UV Stabilizer Masterbatch – Shields polymers from sunlight degradation, ideal for outdoor use.
- Flame Retardant Masterbatch – Enhances fire resistance in electrical, automotive, and building materials.
- Anti-Microbial Masterbatch – Inhibits bacterial growth, used in healthcare, hygiene, and packaging.
- Odor Control Masterbatch – Neutralizes unpleasant smells in recycled or filled polymers.
Visual & Aesthetic Enhancers
- Pearlescent Masterbatch – Adds a shimmering, luxurious finish to consumer goods.
- Matte-Effect Masterbatch – Creates soft, non-glossy textures for premium packaging.
3. Carrier Resin Variants
Masterbatches are classified by their carrier polymers, which ensure optimal compatibility, dispersion, and processing efficiency across various plastic systems. Selecting the right carrier resin is key to achieving consistent performance and desired end-use characteristics.
PP (Polypropylene)
- High heat resistance and rigidity
- Ideal for packaging, automotive parts, and household items
PE (Polyethylene)
- Highly versatile and flexible
- Used in films, pipes, and consumer goods
PVC (Polyvinyl Chloride)
- Compatible with both rigid and flexible PVC applications
- Common in construction, medical, and electrical products
EVA (Ethylene-Vinyl Acetate)
- Offers flexibility, adhesion, and clarity
- Used in laminated films, footwear, and packaging
PS (Polystyrene)
- Suitable for clear, rigid, and dimensionally stable applications
- Found in containers, cutlery, and display items
PET (Polyethylene Terephthalate)
- Known for high strength, clarity, and chemical resistance
- Widely used in bottles, textiles, films, and engineering applications
