Product Brief
Quartz cotton is made of pure quartz fiber, no binder, amorphous, continuous, lumpy, white, tasteless and non-volatile. The irregular length, shape and arrangement of the fiber make the quartz cotton have a curly appearance, prevent the compression of the filling material, and improve the insulation performance; It is a good substitute for high silicon oxygen fiber cotton, ceramic fiber cotton and basalt fiber cotton.

Product advantage

1. Quartz cotton can be used at 1050ºC for a long time, and the temperature can reach 1500ºC for a short time.
2. It has excellent thermal shock resistance, low thermal conductivity, and crimped shape to reduce excessive compression caused by filling in construction.
3, Low thermal conductivity, thermal shock resistance, low heat capacity, excellent high temperature insulation performance, long service life;
4, with good low temperature and high temperature strength; Has good thermal insulation performance;
