Sodium Sulfate (Na₂SO₄) Transparent Filler is a high-quality masterbatch formulated from inorganic transparent powders and specialized functional additives, integrated within a Polyolefin (PP, PE) carrier resin. This advanced transparent masterbatch is engineered to enhance the structural integrity of plastic products while maintaining excellent optical clarity and surface finish.
Key Advantages
-
High Transparency & Gloss: Unlike calcium carbonate, Sodium Sulfate provides a much higher level of clarity, making it virtually invisible in the polymer matrix and significantly enhancing the surface gloss.
-
Enhanced Mechanical Strength: Improves the tensile strength and toughness of the final products, providing better structural integrity.
-
Excellent Dispersion: The fine particle size of Na₂SO₄ ensures smooth mixing and prevents “fish eyes” or surface imperfections during production.
-
Cost Optimization: Allows for high filler loading (up to 30-50% depending on the application) without sacrificing transparency, effectively reducing the overall production cost.
-
Eco-friendly & Non-toxic: Completely safe for food-contact applications and environmentally friendly.
Industrial Applications
-
High-Clarity Film Blowing: Specifically designed for premium packaging such as LLDPE/LDPE stretch films, transparent shopping bags, and high-quality food wraps.
-
Extrusion Coating: Ideal for coating layers where transparency and surface smoothness are critical requirements.
-
Injection & Blow Molding: Used for manufacturing transparent household containers, bottles, and toys where a high-end look is desired.
-
Plastic Sheets & Profiles: Enhances the rigidity and finish of transparent plastic sheets and architectural profiles
Standard Specifications
