High Carbon Natural Expandable Graphite Powder For Fire Resistance
Coating
Expandable graphite, also called Flexible graphite, is made from
high quality natural flake graphite by chemical treatment.The
material has the characteristics of high temperature resistance,
thermal conductivity, lubricity, stable chemistry, heat shock
resistance etc.
It can be used for making sealing material, wear-resisting
material, anti-corrosion material, fire proof material, heat
insulation material, etc.
According sulpur content,it was divided as follows:
- Starder expandable graphite
- Low sulfur expandable graphite
- No sulfur expandable graphite
According sulpur content,it was divided as follows
- High carbon expandable graphite
- Meduim carbon expandable graphite
- High purity expandable graphite
1. Produce low sulfur or no sulfur expandable graphite
2. Standard graphite powder
3. Large Production capacity and good quality
Advantages: Expandable Graphite has features of good expandable,
and its products have the Features of high temperature resistance,
hot insulation, lubrication and chemical stability.
Usage:
(1) additive of metallurgical industry
(2) materials of flexible graphite.
(3) absorbent materials of battery
(4) additive of lubricant
(5) additive of refractory
