Filler Masterbatch & Modifier

A filler masterbatch is a concentrate of finely ground mineral fillers (like calcium carbonate or talc) in a carrier resin used to modify plastic properties.

filler masterbatch & modifier

Filler and modifier masterbatches are used to enhance or adjust the physical and mechanical properties of plastics. These include mineral fillers like calcium carbonate and talc, as well as polymer modifiers that improve impact strength and performance.

a) Filler Masterbatch

A filler masterbatch is a concentrate of finely ground mineral fillers (like calcium carbonate or talc) in a carrier resin used to modify plastic properties.

Calcium Carbonate (CaCO₃) Filler Masterbatch: The most common type, used for its cost-effectiveness and ability to enhance stiffness, opacity, and surface finish. It's widely used in packaging, film, and injection molding.

Talc Filler Masterbatch: Improves rigidity, heat resistance, and dimensional stability. It is often used in automotive and electrical applications where these properties are critical.

b) Modifier Masterbatch

A modifier masterbatch is a concentrated additive that is mixed with a base polymer to alter or improve its physical and mechanical properties, such as impact resistance, melt flow index (MFI), processing, and strength — used to create more durable, reliable, and cost-effective plastic products.

Impact Modifier Masterbatch: Enhances a polymer's toughness and strength, especially at low temperatures, by adding elastomeric properties to brittle plastics like PVC, PMMA, or PP. This improves performance in high-stress applications and helps revive recycled materials.

ALPHA Modifiers: ALPHA opaque modifiers are specialized materials used to enhance the properties of polyolefin-based products by incorporating tailored additives. These modifier masterbatches allow manufacturers to adjust characteristics such as opacity, strength, or durability to meet specific application needs. This cost-effective and efficient approach enhances the versatility of polyolefins, making them suitable for a wide range of applications, including packaging, automotive components, and consumer goods.

c) Moisture Masterbatch

A moisture masterbatch, also called a desiccant or anti-moisture masterbatch, is an additive that absorbs moisture from plastic materials during processing, preventing defects like holes, cracks, and foam.

How it works
  • Moisture absorption: The desiccant masterbatch contains active desiccating agents that bond with and remove water molecules from the plastic melt during processing.
  • Defect prevention: This process prevents the moisture from turning into steam and creating issues like blisters, silver streaks, fisheyes, and poor surface finish in the final product.
  • Improved product quality: By eliminating moisture, it helps maintain the integrity of the plastic, improves its strength and surface gloss, and allows for the increased use of recycled or degraded materials.
Desiccant Masterbatch - Calcium Oxide (CaO) Based

The most common type — absorbs residual moisture during processing. Prevents hydrolysis, voids, and surface defects.

Uses: PP, PE, PS, ABS, Nylon
