Product Overview
1.Product Description
The TF-600 thermal conductive powder is made of several inorganic minerals treated by grain size distribution and equivalent chemical modification and is a kind of cost-effective thermal conductive material with high heat conductivity coefficient. It is widely used in the manufacturing fields of copper-clad plates, LED lamp holders, engineering plastics, refrigerator ice cubes, cell phones, computer CPU, conducting strips, conducting paste (grease) and putty between communication hosts and heat radiators.
According to chemical structural changes of the substrates, it can be developed into several targeted products completely dispersible in epoxy resin, polyacrylic ester resin, polyurethane resin, amino resin, silicon rubber and engineering plastics like PA, PE, PP,PS and ABS and can produce targeted products completely dispersible in silicon rubber, amine resin , polyacrylic ester, epoxy resin and polyurethane resin.
There are "slurry" and "powder" two kinds of supply states, and slurry solvents are designated by the customer or we recommend.

Tips
6. Tips:
When purchasing TF-600 thermal-conductive powder, you are supposed to tell us which types of silicon
rubber, amino resin, polyacrylic ester resin, epoxy resin and polyurethane resin you substrate belongs to.
The TF-600 Thermal-conductive powder is designed according to precise formula and adding powder of other material or grain size will possibly lower heat conductivity coefficient and heat conductivity coefficient for terminal products of different substrates will change
The TF-600 thermal-conductivity powder should be disposed in a dry place with good ventilation and avoid sun exposure so as to prevent the molecular structure of the powder surface from changing to cause bad effect in use.
