Research & Development
This diagram shows clearly that the most important Mechanical properties of the GOLCHA GROUP TALCS exceed by far the properties of the Standard Talcs. Because of its High Aspect ratio BESTA TALC imparts high reinforcement. SUPRA and ALIT TALCS exhibit a very balanced Stiffness/Impact Strength ratio.
