Engineering Performance Into Every Polymer
Overview
The plastics and polymers industry is the largest consumer of mineral fillers globally. Minerals improve mechanical properties, reduce costs, enhance processing characteristics, and add critical functionality to thermoplastics, thermosets, and elastomers. From polypropylene automotive bumpers to PVC pipes and wire insulation, mineral fillers are essential components that transform base polymers into high-performance materials suited for demanding applications.
What We Supply
Each mineral is selected and processed to deliver consistent, application-specific performance in polymer systems.
Polymer / Plastic Grade
The most critical mineral filler for polypropylene. Acts as a nucleating agent, increasing crystallization rate and improving stiffness. Increases flexural modulus by 30–80% and reduces the thermal expansion coefficient. Improves heat deflection temperature significantly.
Acicular Reinforcement
Acicular (needle-like) mineral providing reinforcement similar to short glass fibers at lower cost. Improves tensile strength, flexural modulus, and dimensional stability while reducing warpage and shrinkage. Aspect ratio 15:1 to 20:1. CaSiO₃ >95%.
China Clay
Versatile filler for wire and cable insulation compounds. Improves electrical resistance and is widely used in PVC compounds for cost reduction while maintaining key properties. Also serves as a rubber filler, improving tear strength.
Precipitated Calcium Carbonate
Primary filler in PVC compounds including pipes, profiles, and cables. Functions as an impact modifier in rigid PVC, reducing cost while maintaining impact strength. Rubber reinforcing filler that improves tensile strength and tear resistance. Available in 1–20 micron range.
Applications
Talc-filled polypropylene for dashboards, door panels, and bumper fascias. Typical loading levels of 20–40% deliver the stiffness, dimensional stability, and surface quality that OEMs demand.
HDPE bottles and PP containers with talc for improved stiffness and reduced cycle times. Enables down-gauging while maintaining mechanical performance and shelf appeal.
Kaolin and PCC in insulation and sheathing compounds. Delivers the electrical resistance, flame retardancy, and mechanical properties that cable specifications require.
Appliance housings, furniture components, and household items. Mineral fillers improve surface finish, reduce warpage, and lower material cost in injection-molded parts.
PVC pipe compounds, profile extrusions, and industrial containers. PCC and kaolin provide the balance of cost, processability, and mechanical performance for large-volume production.
