Talc Filler Masterbatch
Mineral-loaded masterbatch for stiffness, dimensional stability and cost reduction.
Talc Filler Masterbatch adds stiffness and heat tolerance to plastic parts. Talc is a lamellar mineral that comes in plate-like particles. When dispersed into a plastic, those platelets line up with the flow of the melt and act like internal reinforcement. The finished part is stiffer, holds its shape better under heat, and stays dimensionally stable as it cools.
It is the filler of choice for polypropylene applications where the part needs to feel rigid and survive warm operating environments, such as automotive components, appliance housings and rigid packaging.

Key benefits
Adds stiffness & rigidity
Lamellar talc platelets reinforce the polymer matrix, raising flexural modulus and producing stiffer finished parts.
Improves dimensional stability
Reduces mould shrinkage and warpage so moulded parts hold tight tolerances as they cool.
Heat-resistant in PP compounds
Lifts heat-distortion temperature, supporting parts exposed to warm operating environments.
Cost-effective filler vs neat resin
Substitutes a portion of base polymer with mineral content, lowering compound cost without sacrificing performance.
Applications
Frequently asked questions
Which polymers does it work with?
It is most commonly used with polypropylene, where the lamellar talc structure delivers its strongest stiffening and heat-resistance effect. It also runs cleanly in polyethylene compounds. We match the carrier resin to your host polymer at the enquiry stage.
What does talc do that calcium carbonate does not?
Talc is a lamellar mineral with a plate-like particle shape, while calcium carbonate is largely equiaxed. The platelet shape gives talc a stronger stiffening effect, higher heat-distortion temperature and better dimensional stability in polypropylene. Calcium carbonate is the cost-down filler of choice; talc is the performance filler when stiffness and heat tolerance matter.
What applications is it used in?
Automotive components such as bumpers and interior trim, appliance housings, rigid packaging, thermoformed sheet, and any polypropylene part that needs higher stiffness, better heat resistance and tighter dimensional control.
Can I get a trial sample?
Yes. Share the host resin, your end application and the property targets you are working to. We supply a matched grade with a Certificate of Analysis and processing recommendations so you can run a clean trial on your own line.
How is the product supplied?
Free-flowing pellets ready for use on a standard masterbatch dosing unit at the hopper. Every shipment is accompanied by a Certificate of Analysis and we manufacture under our ISO 9001:2015 quality system.
