Below is a great post on material that entry or entrance mats are made from. What makes a good walk off mat? A lot has to do with the material its made from. When looking at an carpet entrance mats or carpet runners for commercial use or home - residential use, keep in mind what is the backing made from also. Rubber backing will last longer and hold up better than the plastic or vinyl backing. We have only seen one company (the Andersen Company)  that offers different backings, one for laying the entrance matting over carpet and one over hard floors. The hard floors backing would be smooth and with rubber it will hold nicely. Over carpeting the entry mats would have a cleated backing, this will end any floating or movement the mat might have.

Nylon vs. Olefin

Whats the difference in entry mats or entrance matting?

----------------------------------------------------------

NYLON
Nylon is utilized in approximately 65% of the carpet sold in the U.S. It is a very durable fiber with excellent performance characteristics. Its strengths include good resiliency, good yarn memory to hold twist, good carpet cleaning efficacy, good stain resistance with stain treatment applied, good soil hiding ability, and good abrasion resistance. Nylon is manufactured in both BCF and staple fiber. It is the strongest fiber, making it an excellent choice for the heavy traffic of an active household or commercial facility. It's also the most durable of the synthetics. It is soil and mildew resistant and resilient, but is prone to static. Most nylon is treated with an anti-static treatment to reduce static. Continuous filament fibers minimize pilling and shedding.

OLEFIN
Olefin makes up about 30 % of the fiber used in U.S. carpet manufacturing today. Its strengths include superior stain resistance, with the exception of oil-based stains, and low cost. It is a solution-dyed product, which means color is added during extrusion in its molten state rather than topically applied. (Imagine a carrot vs. a radish). Because of this dye method it has superior resistance to bleaches and sunlight fading. However it has poor resiliency, which can lead to crushing. Color selection is limited due to its dye method. It has poor abrasion resistance and its low melt point can cause fibers to fuse if furniture or other objects are dragged across its surface.

NYLON
This is the most commonly used fiber in carpet today because it is strong, easy to dye, and readily available. There is still no stronger carpet fiber on the market today. If you have any traffic paths at all, I strongly recommend you buy a nylon carpet and forget about those other fibers.

Polypropylene or Olefin:
This is one of the most color fast fibers on the market. It also is one of the most naturally stain resistant. Thus, this fiber is best suited for indoor-outdoor carpet in both loop and grass styles. Olefin is a cheap fiber. It performs well in wear tests if the profile of the pile height is super low. If one adds air to the fiber to give it some bulk (so it feels good), it will not produce a carpet that looks good for longer than six months. This puffed up Olefin will crush!
