Frequently Asked Questions

1. CAN YOU CUSTOMIZE MATTING?

We don’t offer custom made mats! Although we do have many lengths and widths for most products, so you should be able to find a size that will fit your needs.

2. ARE YOUR PRODUCTS RESISTANT TO CHEMICALS AND INDUSTRIAL FLUIDS?
Download the manufacturer Chemical Resistance Guide for a complete list of tested products.
If your chemical is not on the chart, please call us for further guidance. Before you call, please have specific information including an MSDS of the chemical in question, if available. If the chemical is quite caustic, or if we cannot definitively answer your questions, you can request a sample for testing from the manufacturer.

3. WHERE DO I FIND PRODUCT SPEC SHEETS?
Up to date product specifications are available when ever and where ever you want it- all from the MATSonline website! Simply go to any product page and click on the download or print icon in the top right-hand corner.

4. WHERE DO I FIND THE MSDS FOR A MAT?
MATSonline sells products that fall under the definition of “Articles” as outlined by OSHA. This means that under normal conditions, there is no expectation that the products release amounts of hazardous materials that pose a physical hazard or health risk to our customers. So no MSDS is available or required for goods.

6. WHAT IS THE LIFE EXPECTANCY OF THIS MAT?
The life expectancy can vary dramatically depending on a multitude of factors such as: foot traffic, exposure to oils, caustic chemicals or fluids, excessive temperatures, cleaning and maintenance schedule, compound, etc. The following are general guidelines based on our customers’ experience (your experience may vary):

5 Years or more - Urethane Mats (Ex: Rejuvenator®)
3 to 5 years - SpongeCote® Mats (Ex: Diamond-Plate SpongeCote®) and Injection molded PVC (Ex: ErgoDeck®)
2 to 3 years - Molded Rubber Mats (Ex: 24/Seven®)
6 to 12 months - PVC Sponges (Ex: Tuf Sponge)

7. WHAT IS THE DIFFERENCE BETWEEN AN ESD AND A NON-CONDUCTIVE MAT?
ESD mats protect sensitive equipment by drawing static electricity off workers before they touch susceptible chemicals or apparatus. Humans quickly generate static electricity through friction caused by walking or using chairs with casters. With a simple touch, this static electricity is passed from the person to sensitive electronics. One such shock can destroy internal microchips or cause a spark that can ignite flammable chemicals. However, if the person steps on a ESD mat, the static is safely transferred from the person to the ground.

Most commonly called Switchboard Matting, non-conductive mats insulate and protect workers from deadly shocks generated by high voltage equipment. (This type of electrical shock is dangerous because it has high amperage.) These mats will not allow the electricity to conduct through the worker, and hence protects workers from serious injury.

8. WHAT DOES COEFFICIENT OF FRICTION MEAN?
Coefficient of Friction or COF is the measure of traction provided by the surface of the mat. It is a measurement of force that must be exerted before an object slips. Therefore, the higher the number, the better the traction. OSHA recommends a minimum COF of .5 in dry areas and .25 in wet. The ADA recommends .6 on flat surfaces and .8 on ramps

9. I HAVE AN ESD ANTI-FATIGUE MAT, BUT MY EMPLOYEES STILL GET STATIC SHOCKS AND I AM AFRAID THIS STATIC DISCHARGE IS DAMAGING OUR PRODUCTS. WHAT IS THE PROBLEM?
There are two possibilities:

The mats are not grounded. Every ESD mat has a snap to connect to a ground cord, which then must be grounded to an electrical outlet or similar conduit. If the mat is not grounded there is no place for the static electricity to go. The employees will still be able to pass it on to the equipment.

The employees have insulated shoes and are not wearing heel grounders. Most shoes have soles that are not designed to conduct electricity (i.e. any shoes with rubber soles for example). In order to allow the static electricity to flow off the employee, he or she must wear heel grounders and the long fabric strip must touch his or her skin.

10. HOW SHOULD I GROUND MY MODULAR ESD MATS?
Modular ESD mats have a resistance between 3x10^4 and 5x10^5 ohms which falls in the low end of the conductive range. There are two different methods for grounding these mats.

Use a conductive coating for the floor where the mats are used. This method prevents the need for grounding cords. There are various resistance ranges for coatings to meet the various needs of each user.

A second method for grounding utilizes snaps. While each user’s needs are different, a good rule of thumb is the resistance will go by a factor of 10 for every seam between an area and the nearest grounded snap. For example if you have 3 mats connected end to end and the one on the far left is grounded the resistance at the far right will be 3x10^7 ohm.

Different users will require different resistances to ground. It is important to test the mat at various places to ground and set up the area to meet your individual requirements. If you aren’t sure where to start we suggest that you begin with no more than 2 ungrounded tiles between grounded ones.

11. HOW CAN I TELL HOW SOFT A MAT WILL BE?
The actual test for softness is determined by the material and manufacturing process of the mat. There are two that conform to describe the products we sell:

Compression Deflection - This is one way of measuring the softness or comfort level of a sponge mat. It measures how much a person’s foot sinks into the mat – the higher the reading, the softer the mat. The results are affected by the thickness of the sponge backing and the flexibility of the surface material. We consider .20 - .5 the ideal range using the ASTM D575 test methods.

Durometer - The measure of hardness/softness of molded rubber and molded PVC mats. As a general rule, the lower the durometer, the softer the mat. Most of them at products we sell range between 45-70 durometer. We consider between 45 and 65 durometer to be ideal range for molded rubber mats using the ASTM D2240 test methods.

12. DON’T SHOES AND INSOLES DO THE SAME THING?
There’s no question that having the right footwear is important, but when it comes to health, safety and performance, the surface matters!

13. HOW DOES MATSonline COMPLY WITH CALIFORNIA PROPOSITION 65?
California Proposition 65: The State of California requires that certain warnings be given concerning products which contain chemicals subject to Proposition 65. The products we sell are made from virgin and recycled materials. To determine whether a product contains one or more of the listed Proposition 65 chemicals, manufacturers can have their products qualitatively tested for the presence of such chemicals or make a determination based on information provided by its component suppliers. When recycled materials are used as a component of a product, it can be difficult, if not impossible for a manufacturer to determine whether Proposition 65 chemicals are contained in the product and in what concentration due to variability in recycling lots, without testing each batch/lot. In such cases, if it is reasonable to expect the product may contain a listed chemical, the manufacturer may choose to provide a warning for all such products. 
MATSonline is fully committed to providing safe and environmentally friendly products to our customers. MATSonline has made a determination the manufacturers of the products we sell are compliant with Proposition 65 warnings on their packaging.
