White Masterbatch is a concentrated mixture of high-quality titanium dioxide (TiO₂), polymers, and performance-enhancing additives, designed to deliver excellent whiteness, opacity, and dispersion in plastic applications.
It is used as a colorant and functional additive in various thermoplastics to improve brightness, surface finish, UV resistance, and processing efficiency.
Key Features
- High TiO₂ content (typically 40–80%)
- Excellent dispersion and covering power
- Superior opacity and color consistency
- UV resistance and thermal stability
- Suitable for food-contact (FDA/REACH-compliant grades available)
- Compatible with a wide range of polymers (PE, PP, PS, PET, etc.)
- Customized grades available for different applications and processing methods
Main Applications
1. Film Extrusion
- Blown and Cast Films: Provides uniform whiteness and opacity for packaging films.
- Lamination Films: Ensures smooth surface and printability.
2. Injection & Blow Molding
- Used in production of white containers, caps, bottles, and household products, offering high gloss and UV protection.
3. Sheet & Thermoforming
- Offers high opacity and smooth finish in PP/PS sheets, trays, and packaging items.
4. Fiber & Non-Woven
- Delivers brightness and thermal stability for non-woven fabrics, textiles, and geotextiles.
5. Pipe & Profile Extrusion
- Enhances UV resistance, whiteness, and processing stability in PPR and HDPE pipes and profiles.
