Welcome to Imerys Performance Minerals

Compressed tablets

COMPRESSED TABLETS Imerys minerals are ideal glidants, lubricants and diluents for compressed tablets

Imerys talcs are used as lubricants and glidants in compressed tablets. Imerys calcium carbonates are good diluents for wet granulated products. 

Used as glidants / flow agents, Imerys talcs:

  • Reduce fluctuations in tablet weight

  • Enhance tablet homogeneity and quality

  • Increase productivity

Used as lubricants for tablet presses, talcs:

  • Reduce friction

  • Prevent tablets sticking to punch face during compressing

  • Facilitate die ejection

Calcium carbonates are excellent diluent solutions for wet granulated products or when high whiteness is required. 

We recommend 

  • Luzenac Pharma talc range as flow agents and lubricants

  • Calcius precipitated calcium carbonate range as a diluent for wet granulated products and for whiteness

Imerys minerals are suitable for swallowable, chewable and effervescent compressed tablet production.
