●Very low coefficient ofthermal expansion 

● Excellent conductivity and Electrical property

● High Chemical Resistance

● Pure(high SiO2 content, lowFe, Na, K & Ti)

●High Whiteness

●High Hardness, good wearable

 

Main Applications:

● EMC (Epoxy Molding Compound) Filler, coating powder

●Electrical Insulators

●Others
