Both layers are made from vulcanized synthetic rubber, which offers excellent resistance to oil, grease and most common solvents. They offer superior resistance to heat and hot solder as compared to vinyl or olefinic materials. Non-standard sizes are available on a custom order basis. Dissipative table mats include two Snap Fasteners 3034 (installed) and one Wrist Strap Grounding System 3048.
