Anti Static Soldering Mat Kits are designed for electronic repair or assembly facilities to protect static sensitive components during the soldering process. These anti static mats offer resistance up to 210 degrees Fahrenheit. They are made of two layers - a static dissipative rubber layer at the top and a black conductive rubber layer at the bottom. Bertech's Anti Static Soldering Mat Kits include the mat, a wrist strap, and a grounding cord. These mat kits offer excellent resistance to oil, grease and most common solvents, hot solders and soldering irons.They are also known as Anti Static Two Layer Rubber Mat Kits.
