DONACARBO Milled
DONACARBO MILLED is powder-like form, which is made by cutting the original fiber into less than 2 mm. It is completely dispersed to various materials, such as powder, pellet, liquid, and viscous resins, and show good electroconductivity, chemical resistance, and anti-corrosion. To meet a wide variety of applications, various fiber lengths are available in our product line.
Applications
Additives in thermo-plastic and thermosetting resin
For reinforcement
Improvement of sliding performance
Electrical properties
Improvement of sliding characteristics and thermal dimensional stability of fluoro-plastic
For clutches and brakes
