 Product Introduction
 
DEFINITIONS
High purity tungsten wire (99.95% tungsten), enriched with K20, Si02 and Al203, gives physical qualities (tear resistance, Specific resistance, surface roughness).
 
A layer of graphite covers the surface of the tungsten wire and gives him a matt black aspect.
 
FIELDS OF APPLICATION
The resistant tungsten wires are intended for the production of heated laminated glass for automotive market
These tungsten wires are bounded on PVB sheet by means of local heating and pressure.
Prepared PVB sheets are assembled inside bended glass for final products
 
Physical Properties
The electric resistance of the tungsten wire has a tolerance of +/-3 % of its nominal value. The resistance of the wire is defined as the resistance measured at 20°C
