Functional Fillers for the Plastics Industry

Overview

The plastics industry is one of the largest consumers of mineral fillers globally. Raviraj Minerals is a trusted supplier of coated and uncoated talc, calcium carbonate, dolomite, and kaolin for injection molding, extrusion, blow molding, and rotational molding applications across polyolefin, PVC, and engineering polymer systems.

Talc Powder

With the plastics industry on a high growth trajectory, talc usage is expanding rapidly across PP, HDPE, LDPE, PVC, ABS, and thermosetting compounds. Our talc powders for plastics are available from 300 mesh to ultra-fine 10 µm grades, enabling applications from basic cost reduction to high-performance reinforcement.

Improves stiffness, hardness, and tensile strength of plastic products
Provides superior thermal and electrical resistance
Enhances surface quality and imparts a smooth feel
Chemically inert — ideal for food-contact and medical-grade applications
Suitable for PP, HDPE, LDPE, PVC, ABS, and thermosetting compounds

Calcium Carbonate

Our calcite powder is widely used in plastics as a filler due to its high dispensability, low oil absorption, high impact resistance, smooth surface finish, easy processing, and excellent dimensional stability. It is indispensable for delustering of naturally transparent man-made fibers and guarantees high color intensities in plastic components.

High brightness and whiteness for appearance-critical plastic parts
Low oil absorption enables high loading without processing issues
Improves impact strength in HDPE, PP, and PVC compounds
Excellent dimensional stability in injection-molded components
Available in uncoated and stearic-acid coated grades

Dolomite Powder

Plastic-grade dolomite from Raviraj Minerals is supplied in precise compositions and multiple particle sizes. It is used across rubber, plastic, paint, detergent, and ceramic applications and is recognized for its purity, consistent quality, and cost efficiency.

Used as a white filler in PP, HDPE, and PVC compounds
Improves rigidity and surface aesthetics of plastic parts
Cost-effective alternative to calcite in many formulations
Available in a range of mesh sizes from coarse to ultra-fine

Kaolin / China Clay

Kaolin is available in a range of particle sizes to meet the properties needed for demanding plastic applications. The bonds between kaolin and polymers provide enhanced mechanical strength, improved impact and flex strength, and a high degree of hydrophobicity.
