The polymer has an inherent tack when cured, which will remain for many years. The
SimStep mat has:

1. An optical smooth surface – this allows more contact with the contamination
control surface (Adhesive peel off mats are microscopically very uneven so less of
the shoe or wheel touches its surface)
2. The slightly soft polymer conforms to the shoe or wheel allowing a denser packing
of removed contamination.
3. High energy surface – very smooth, flat surfaces create a high energy level –
Vander Waals theory (Example: two pieces of glass – adhere to each other) This
high energy surface attracts and holds particulate.

Placement Targets
Entryways, gowning room/areas, air locks, material transfer rooms. Around equipment –
film, injection molding, inside and outside aseptic suites, hallways to eliminate cross
contamination.

Determining the size of mat required
The „Z“ movement in gowning rooms allows more footsteps in a smaller area, which

makes it the number one target area.

The size of the SimStep mat will be determined by the traffic volume, cleaning cycle,
cleanliness requirements and space available.

When does the SimStep need to be cleaned?
Polymer floor mats get saturated after multiple over strikes in one area – As personnel
walk over the beginning of the mat this area will become saturated first. Over a period of

time, the contamination is spread out onto the length of the mat. When the area closest
to the cleanroom entrance starts to become saturated, then it is time to clean the mat
Even when the high tack mat surface is saturated, no contamination will be released until
the floor mat is mopped clean with detergent/disinfectant and water

One Example:
Particle counts at entrance remained consistent for 3 month test. 20‘ x 6‘ 6“ SimStep
floor mat removed virtually 100% of foot contamination in a hallway with the traffic of 50
people in one direction each person averaging 6 entrances with the traffic spread over 3
shifts. This mat was cleaned one per day.
