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, Wollastonite.


Phlogopite) and


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.


Kärntner Montanindustrie


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.
