When used in plastics mica, a functional filler, imparts many benefits such as the significant increase of the plastic's stiffness. UltraCarb, another polymer filler, is a halogen-free fire retardant for plastics.
One advantage is the platy nature of mica; the particles align in the same direction during moulding. MicaFort greatly reduces distortion and stiffens the polymer part. Mica is inert and can be used in variety of polymer types and end use applications. Excellent mechanical properties can be achieved with mica addition levels as low as 10 to 20%.
UltraCarb has a unique 3-stage fire retardant mechanism. It is used in a wide range of polymers such as PE, PP and PVC.
