TWO LAYER RUBBER .060" thickness
Description:
Two Layer Rubber meets the worksurface
required limits of ANSI/ESD S20.20
of < 1 x 10E9 ohms. When properly
grounded, the purpose of the Two Layer
Rubber worksurface is two-fold. (1) To
provide a surface where electrostatic
charges are limited, and (2) To provide
a surface that will remove charges from
all conductors (including ESD susceptible
devices and assemblies) that are placed
on the surface. Where potential CDM
(Charged Device Model) damage is a
concern, the worksurface should have a
lower limit of 1 x 10E6 ohms removing
charges at a slower rate. Surfaces that
are <10^6 ohms can discharge ESD
susceptible items too quickly. A variety
of standard size mats are provided for
ESD workstations, shelves, carts or
cafeteria-style trays in an ESD Protected
Area.
Two Layer Rubber is suitable for use with
continuous monitors.

Grounding: This material must be properly grounded for optimum electrial performance.
Cleaning: For optimum electrical performance, surface must be cleaned regularly using an ESD mat cleaner. We suggest using our
Reztore Surface & Mat Cleaner Item #
10435 or Static-Wipes Item
#10600. Do not use cleaners that are not specifically designed for ESD
control use. As they can contain chemicals and/or leave residue that will alter the ESD and physical properties.

Matting materials have a tendency to shrink slightly
when first unrolled. In applications where length is
critical, allow the material to relax for at least 4 hours
before cutting to size. Always trim with a sharp knife or
razor blade.

Desco warrants for 90 days that matting
products will be free of defects in materials
and workmanship. Damage to matting caused
by misuse of any kind, including using
inappropriate cleaners is not covered by Desco
Limited Warranty.
Grounding Intervals for ESD Mats
Sufficient ground cords should be used to
reliably meet ANSI/ESD S20.20 Table 3 less
than 1 x 10E9 ohms for worksurfaces. An
industry recommendation has been that
continuous runs of ESD matting should be
grounded at ten-foot intervals to allow proper
charge decay rates with each individual ESD
mat should be grounded with ground snap
located no further than five feet from either end.
Tolerances:
Width ±.250"
Length ± .250" every 1 linear foot of
running material.
