Bertech ESD Soldering Mats are made from two layers of elastomer designed for table top or workstations. They are Made in the USA. These mats are 0.06" thick and have two layers. The top layer is a blue static dissipative rubber laminated to a conductive bottom rubber layer. ESD Soldering mats have excellent charge dissipation, rapid charge decay, and low turbo generation properties. They withstand higher temperatures and are abrasion resistant. The light textured surface reduces light glare and are easy to clean. They are free from halogens, lead, asbestos, antimony and other dangerous volatiles. Bertech's ESD Soldering Mats offer excellent resistance to heat, oil, grease, and most common solvents. They are RoHS and REACH Compliant.
