SolutionPlastics & Rubber Filler Solutions

Mineral filler systems for plastics, masterbatch, rubber compounds and composite materials requiring stiffness, dimensional stability and controlled cost.

Plastics & Rubber Filler Solutions
Higher stiffness and stability

Talc and mica help improve rigidity, dimensional control and heat-related stability in selected polymer systems.

Processing and cost balance

Mineral fillers support formula economics while maintaining acceptable processing behavior.

Functional composite options

Glass beads and tourmaline can be used for specialty composite concepts where validated performance is required.

Application Areas

Polypropylene and polyolefin compounds

Talc powder is commonly selected where stiffness, heat resistance and shrinkage control are key formulation targets.

• Suitable for injection molding and extrusion trials

• Multiple mesh and D50 options

• Supports cost-performance balance

Engineering plastic and composite materials

Mica powder can contribute lamellar reinforcement and dimensional stability in filled polymer systems.

• High aspect-ratio filler concept

• Improved warpage control potential

• Useful for functional masterbatch development

PVC, cable and profile applications

Mineral fillers can support density control, formula structure and processing behavior in selected PVC systems.

• Talc and mica for filling and structure

• Particle-size selection for surface quality

• Packaging matched to production use

Rubber and elastomer compounds

Talc and mica can act as functional fillers where reinforcement, processing and surface finish must be balanced.

• Supports compounding trials

• Consistent powder flow and packing options

• Custom grades available by request

Recommended Mineral Portfolio

Talc Powder

Recommended for stiffness, surface smoothness, heat-related stability and cost-efficient filling.

Mica Powder

Lamellar filler for dimensional stability, barrier concept and reinforcement in selected compounds.

Glass Beads

Potentially used for density control, surface texture or specialty filled composite systems.

Tourmaline Powder

Specialty mineral for differentiated functional concepts; claims should be supported by testing.
