Quality

Quality control

All our manufacturing units are ISO 9001:2000 certified by TUV-R, Germany. Both in the precipitated chemicals and processed minerals line, our QA system strives to achieve near-zero batch to batch variation through PLC / DSC-controlled unit operations. Tolerance limits are narrow and all non-conformities are strictly dealt with and corrective actions initiated. Quality Assurance Certificate is provided to customers to ensure conformance to their requirements.

We are committed to supplying the quality approved by the customer. Improvement of a quality management system is an integral feature of our organization. We shall review our quality objectives in line with the challenging.

Lab Testing

Our Quality Control system is organized in a unique and innovative three-tier model:

We are gearing towards achieving following testing parameters:
  • Quantitative oxide composition of silicate materials
  • Oxide composition of non-metalliferous raw materials
  • Mineral composition of non-metalliferous raw materials
  • Kaolin Clay and clays mechanical strength of bending
  • Suspensions pH value
  • Kaolin Clay and clays plasticity
  • Chemical content of non-metalliferous raw materials
  • Whiteness and other color data of kaolin, carbonate fillers
  • Dispersive content of kaolin, clays and other microproducts
  • Paper Kaolin Clay abrasiveness
  • Fineness of grinding
  • Bulk materials grain size distribution
