20 Reasons for Choosing TMC Optical Tops, Optical Tables

TMC CleanTop^® II

Competitive Construction

TMC: Formed Steel Sidewalls

Other: Particle board sidewalls

TMC: Steel-to-steel bonding throughout

Other: Weak plastic layer separates core and top skin

TMC: High stiffness, small cell size core, individual nylon cups.

Other: Less rigid, large cell size core; molded plastic cups

1. Sidewalls of TMC tops are 0.75 in. (2 mm) thick, damped, cold-rolled formed steel (see center photo, above), unlike the moisture-absorbing particle board favored by other manufacturers, presumably for its low cost. In addition, steel provides structural integrity unattainable with particle board sidewalls.	2.TMC’s CleanTop ^® design does not require enlarging core cell size because CleanTop ^® II cups are cylindrical, not conical like molded plastic membrane cavities. Our average cell size of 0.5 in.² (3 cm²) is at least 50% smaller than molded cavity top designs, assuring the highest stiffness and greatest core-to-skin bonding contact area.	3. CleanTop ^® achieves a spillproof core with only two bonding layers: top skin to core and core to bottom skin. Imitations must add a third bonding layer, which severely weakens the structure: top skin to plastic layer, plastic layer to core, and core to bottom skin.
