I hear many people tell me that their pad stuck to their floor and it cost them a lot of money to re-finish the floor. The type of pad that does this is an open weave waffle looking pad. It may look and feel like rubber but it actually is a plastic or nylon pad that has a chemical spray applied to it. This chemical is what transfers to the floor and leaves an imprint of the rug pad right on the floor. Real rubber does not harm the floor and a felt and natural rubber carpet pad will prevent slipping and protect the floor.
Protects the floor: Area-rugs can cause scratches to floors. The dust and dirt particles that collect beneath a carpet can easily scratch a floor when it is walked on. Pads under the rugs prevent this from happening.
For finding a rug pad that provides cushioned support, we need to look at thicker pad products that are available. There are thicker open mesh PVC products from China that provide some cushion support. But there is a limit to how thick these products can be due to the way they are made. The core material that is coated with the PVC is a polyester yarn that is knitted into a wide continuous roll. The roll is then fed into a big oven where it is dipped into the PVC material and allowed to cure in an oven. When PVC cures, it expands and has the texture of a sponge thus giving it good gripping properties. But the overall thickness of this pad is controlled by making the knitted material differently so that it can absorb more of the PVC when coated. So the polyester material is a limiting factor to how thick the PVC mesh can be. 1/8" is the approximate maximum thickness we found for this product. Another product that provides cushion support is the rubber backed felt rug pads that are approximately 1/4" thick. We also found felt pads that are approximately 1/2" thick with no rubber backing that provide exceptional cushion support properties. The felt pad types are made with recycled carpet yarns and are fed into a needlepunch machine that creates a specified thickness, 12' wide felt material which is very dense and durable.
