Cleanroom Sticky Mat Size Guide: Choose the Right Size for Contamination Control

Cleanrooms are designed to avoid microscopic contamination of sensitive processes. Be it a pharmaceutical plant, semiconductor plant, laboratory, or even a medical device production unit, every detail counts. One of the things that is normally overlooked is the sticky mat at the entrance.

A large enough sticky mat does much more than just collect dust. It acts as the first line of defense against contamination, and it helps to maintain cleanroom integrity before the entry of people, carts, and equipment into controlled areas.

It is a full cleanroom sticky mat size guide that tells you everything you need to know about selecting the correct size, industry standards, and optimal performance in contamination control.

Importance of Sticky Mat Size in More Than Most Facilities

Most facility managers are so concerned with the adhesive strength and the number of layers, and neglect the size. Nevertheless, choosing an inappropriate size may greatly decrease the efficiency of particle removal. A little sticky mat will allow contaminants to escape the adhesive surface. A large mat will not contribute the same value to the operations and will increase the cost of operations.

The appropriate size guarantees:

•          Prevention of contamination of footwear.

•          Wheel contamination prevention

•          Improved cleanroom entry contamination.

•          Better cleanroom traffic flow.

•          Enhanced particle capture ability.

•          Compliance with controlled environment flooring requirements

Studies and industry experimentation indicate that properly installed and used, adhesive mats can eliminate up to 95% of traffic-borne particles. These dimensions are often provided by manufacturers as they fit into typical doorway dimensions and traffic flows. Special layouts are also often requested to be fitted with a custom cleanroom sticky mat size guide in most facilities.

Choosing Cleanroom Sticky Mat Size: How to Choose Cleanroom Sticky Mat Size

Among the most frequently asked questions by facility managers is:

Doorway Width Mat Sizing

The mat will be used to cover the walking path. General recommendation:

•          Doorway width should not be less than mat width.

•          There should not be any holes on either side.

This makes sure that all employees and visitors will walk directly onto the adhesive surface.

Footfall Coverage Requirements

One step is not usually sufficient to get the best removal of particles. Best practices in the industry suggest:

•          Two or three full steps each.

•          Complete sole contact on entry.

•          Regular patterns of walking on the mat.

The longer mats are superior in capturing the particles as they have more opportunities to contact the surface.

Cart and Equipment Traffic

Facilities should have larger moving carts, trolleys, or wheeled equipment. Benefits include:

•          Better pollution of the wheels.

•          Improved debris capture

•          Less transfer of particulate to clean areas.

A bigger particle trapping floor mat will be used to ensure cleaner production environments where there is high movement of equipment.

Cleanroom Sticky Mat Width and Length Guide

The effectiveness of contamination control is directly affected by the width-length ratio.

Width Considerations

Select a width that:

•          Closes all the entry points.

•          Accommodates wheel traffic

•          Prevents side-step contamination

Length Considerations

Longer mats provide:

•          Increased chances of particle capture.

•          Improved control of shoe sole contamination.

•          Improved performance of flooring in contamination control.

The 36 x 60 setup may be a more suitable option in the large-scale plants.

Best Cleanroom Sticky Mat Size of ISO Cleanrooms

The ISO cleanrooms require more stringent procedures for contamination management. The optimal size of the sticky mat in the ISO cleanrooms depends on the classification level and traffic.

ISO 8 Cleanrooms

Typical recommendations:

•          24" × 36"

•          26" × 45"

ISO 7 Cleanrooms

Typical recommendations:

•          26" × 45"

•          36" × 45"

ISO 5 and ISO 6 Cleanrooms

Recommended:

•          36" × 60"

•          Multiple mat systems

•          Extended entry coverage

The bigger size helps to maintain higher contamination control standards and higher particle reduction efficiency.

Pharmaceutical-Cleanroom Sticky Mat Dimensions

The working conditions in pharmaceutical firms require a high degree of compliance with the requirements of cleanliness and GMP. Correct pharmaceutical cleanroom sticky mat sizes assist:

•          Reduce particulate migration

•          Favor sterile production activities.

•          Enhance contamination control entrance.

•          Protect product quality

Recommended dimensions include:

•          26" × 45"

•          36" × 45"

•          36" × 60"

The larger mats are normally preferred as they can be occupied by the traffic of personnel and the material transfer equipment simultaneously.

Choice of Sticky Mat Size to be Used in Contamination Control

To select the appropriate cleanroom sticky mat size, one needs to consider:

•          Traffic volume

•          Entrance width

•          ISO classification

•          Cart movement

•          Cleaning frequency

•          Operational budget

Facilities that simply select the lowest possible price are more likely to have risks of contamination and more costly maintenance.

Cleanroom Entry Mat Coverage Guide

All cleanrooms should be systematically covered in terms of entry in order to deliver the best results. Recommendations include:

•          Full doorway coverage

•          Two or three footstep points of contact.

•          Movement of wheels on an adhesive surface.

•          Consistent replacement schedules

Sticky mats are an important component of an entire cleanroom floor protection system when combined with gowning processes and air filtration systems.

Technical Requirements to be Taken into Consideration

Besides dimensions, measure the following performance characteristics:

•          Polyethylene construction

•          Acrylic adhesive systems

•          Adhesive force ratings

•          Tensile strength

•          Elongation performance

•          Anti-static properties

•          Layer count

The removal of dust is normally stated to be up to 95 percent of the particles of approximately 0.3 microns when the mats are in good condition.
