Filler Masterbatches

Applications

• Extrusion: to improve stiffness, strength, and impact resistance

• Injection molding: to improve flow properties, reduce shrinkage and warpage

• Blow molding: to improve rigidity and strength of plastic bottles and containers

• Film production: to improve opacity, whiteness, and smoothness of plastic films

• Pipe and profile production: to improve stiffness, impact resistance, and surface finish

• Cable production: to improve tensile strength and flame retardancy

• Rotational molding: to improve dimensional stability, stiffness, and impact resistance

• Thermoforming: to improve surface finish, opacity, and whiteness

• Automotive industry: to improve mechanical properties and reduce weight of automotive parts

• Packaging industry: to improve stiffness, strength, and barrier properties of plastic packaging materials

• Electrical and electronics industry: to improve strength, dimensional stability, and flame retardancy of plastic electrical and electronic components.

Loading Percentages:

In general, the loading percentage of filler masterbatches typically falls within a range of 10% to 40%. Here's a breakdown of loading percentages in filler masterbatches:

• Plastic Extrusion (e.g., pipes, profiles, sheets):

1. Low Loading (10%-20%): In some cases, a low loading of filler masterbatch can be used to reduce material costs without significantly compromising the mechanical properties of the plastic products.

2. Medium Loading (20%-30%): Many plastic extrusion applications use filler masterbatches in this range to balance cost savings with maintaining essential properties.

3. High Loading (30%-40% and above): Some non-critical applications, such as utility pipes, may use high loading percentages to achieve substantial cost reductions.

• Blow Moulding (e.g., bottles, containers):

1. Low to Medium Loading (10%-30%): Blow-molded products often use filler masterbatches to improve stiffness, reduce weight, and lower production costs while maintaining product quality.

• Injection Moulding (e.g., automotive parts, consumer goods):

1. Low to Medium Loading (10%-30%): Injection-molded parts can benefit from filler masterbatches in this range to enhance dimensional stability and reduce manufacturing costs.

• Film and Packaging (e.g., bags, packaging films):

1. Low Loading (10%-20%): Filler masterbatches are used to reduce film thickness, improve barrier properties, and decrease material costs.

2. Medium Loading (20%-30%): Some films may use higher loading percentages to achieve specific properties like opacity and rigidity.

• Wire and Cable Insulation:

1. Medium Loading (20%-30%): Filler masterbatches are added to cable insulation compounds to improve electrical properties and reduce production costs.

• Rubber Compounding (e.g., tires, conveyor belts):

1. Medium Loading (20%-30%): Rubber formulations often incorporate filler masterbatches to improve wear resistance, reduce rolling resistance, and enhance cost-effectiveness.

• Construction Materials (e.g., PVC pipes, roofing membranes):

1. Medium to High Loading (20%-40% and above): Building materials may use higher loading percentages of filler masterbatches to meet specific structural and cost requirements.

• Automotive Parts (e.g., interior components, under-the-hood parts):

1. Medium Loading (20%-30%): Automotive applications often utilize filler masterbatches to reduce weight and improve dimensional stability.

• Thermoplastic Compounds (e.g., masterbatches for colouring, UV protection):

Loading percentages can vary widely depending on the desired colour or additive effects. It can range from low to medium loading, depending on the application.
