FAQ's
Calcium Carbonate Masterbatch is a concentrated mixture of calcium carbonate (CaCO₃) combined with a polymer resin. It is used as a filler in the production of plastic materials to reduce costs and improve certain properties.
Calcium Carbonate (CaCO₃) Masterbatch is commonly added to plastic manufacturing processes, primarily in extrusion, injection molding, and blow molding. The process involves the following steps:
- Weighing and Dosing
- Blending
- Feeding
- Melting and Compounding
- Shaping and Cooling
- Final Product
Calcium Carbonate Masterbatch is widely used in:
- Blown films: Packaging films, shopping bags.
- Injection molding: Household items, automotive parts.
- Extrusion: Pipes, sheets, and profiles.
- Blow molding: Bottles and containers.
It is typically added directly into the polymer melt during the extrusion, injection, or blow molding processes, ensuring an even distribution within the plastic matrix.
Yes, it is considered environmentally friendly because it reduces the overall amount of petroleum-based polymers required, potentially lowering carbon footprints.
If stored in proper conditions (cool, dry place, away from direct sunlight), it typically has a long shelf life, often over a year, without significant degradation.
Additive Masterbatch is a concentrated mixture of various functional additives encapsulated in a carrier resin, which is added to plastics to impart or enhance specific properties, such as UV stability, anti-static properties, flame retardancy, or color.
Common types include:
- Polymer Processing Aid: Improves the flow and processability of polymers during manufacturing.
- Optical Brightener: Enhances the brightness and whiteness of plastics by absorbing UV light and re-emitting it as visible blue light.
- Antiblock: Prevents plastic films from sticking to each other during production or use.
- Slip: Reduces the coefficient of friction between plastic surfaces to improve sliding and handling.
- Desiccant: Absorbs moisture during the processing of hydrophilic polymers like recycled plastics.
- Antifog: To prevent the formation of fog or water droplets on the surface of plastic films.
- VCI: Create a protective layer on the surface of metal items, preventing rust and corrosion.
- Anti-static: Reduces the buildup of static electricity on the surface of plastic products.
- Antioxidants: Protects the polymer from oxidative degradation during processing and throughout the product’s lifecycle.
- Antirodent :To repel rodents and prevent damage caused by gnawing.
- Nucleating Agent: Improves the crystallization rate and density of semi-crystalline polymers.
- UV Stabilizers: Provides protection against ultraviolet (UV) light,which can cause polymer degradation.
- Flame Retardants: Imparts fire-resistant properties to plastics. Slows or inhibits the spread of flames and reduces smoke generation during combustion.
- Antimicrobial: Provides protection against bacteria, fungi, and other microorganisms.
- Oxo-biodegradable: Promotes the degradation of plastic materials under specific environmental conditions. It is designed to accelerate the breakdown of conventional plastics, such as polyethylene (PE) or polypropylene (PP), into smaller fragments, making the material more susceptible to microbial action and facilitating its eventual biodegradation.
- Better dispersion: The additives are pre-dispersed, ensuring uniform distribution in the polymer matrix.
- Simplified handling: Masterbatch comes in pellet form, making it easier to handle compared to powders or liquids.
- Precise dosing: Ensures consistent addition of additives, reducing
waste or overuse.
Yes, additive masterbatches can be tailored according to the required functionality, polymer type, and processing conditions.
Yes, multi-functional additive masterbatches can be created to deliver several properties, such as a combination of UV stabilizers, antioxidants, and slip agents, tailored to meet specific product needs.
White Masterbatch is a concentrated mixture of a white pigment, typically titanium dioxide (TiO₂), combined with a polymer carrier resin. It is used to impart white color and opacity to plastic products.
Yes, White Masterbatch can be used with other masterbatches like Filler or additive masterbatches, depending on the desired properties (e.g., combining UV stabilizer masterbatch for outdoor applications).
Yes, it can be tailored to meet specific application needs, including the concentration of TiO₂, choice of carrier resin, and the inclusion of additional additives such as UV stabilizers, slip agents, or processing aids.
Sodium Sulfate Based PE Masterbatch is a type of filler masterbatch where sodium sulfate (Na₂SO₄) is dispersed in a polyethylene (PE) matrix. It is used to reduce the overall material cost and modify the physical properties of plastic products.
PBAT (Polybutylene Adipate Terephthalate) and PLA (Polylactic Acid) are biodegradable polymers often combined to create compostable compounds. These materials are designed to break down under composting conditions, offering an eco-friendly alternative to traditional plastics.
