PA 6 filled with glass fiber and Mica HLP 100—Test Results Shrinkage


Kärntner Montanindustrie (KMI) is a world leading mining and processing company dealing with  Micaceous Iron Oxide (MIOX®) 


KMI uses unique processing  technologies for micronization of high aspect ratio minerals 


KMI‘s product range includes 


Kärntner Montanindustrie (KMI),  located in Austria, is the market leader in Micaceous Iron Oxide (MIOX®). KMI, as a specialist in micronization of high aspect ratio (HAR) minerals,  extended their product portfolio to Mi- ca (Muscovite, Phlogopite) and  Wollastonite. 


These minerals have a higher aspect ratio, either platy or acicular, and they heavily influence the crucial properties of thermoplastic polymers, such as stiff- ness, heat distortion temperature, di- mensional stability and surface scratch resistance.


Shrinkage and warpage reduction 


 KMI’s MICA Phlogopite 


Polyamide is often reinforced by glass fiber which leads to the problem of ani- sotropic shrinkage and therewith the risk of warpage. Glass spheres are often used to avoid that effect but with a negative impact on mechanical proper- ties and heat distortion temperature. 


With KMI’s Phlogopite in combination with glass fiber that challenge can be solved. Reinforcement is provided with a high heat distortion temperature and optimal mechanical properties without warpage. 

Mica has a significant influence on the shrinkage; it reduces the overall shrink- age and balances the anisotropism compared to the pure glass fiber com- pound and compared to the addition of glass spheres as well; also HDT is higher and mechanical properties are ideal.
