CHEMFAB® PTFE coated fabrics are used in various flooring applications. In floor manufacturing, CHEMFAB PTFE (Teflon™) belting products are often used as a liner for the flooring material. In order to act as a liner, the belts are cured in an oven, so they must be able to withstand high temperatures.CHEMFAB PTFE-coated fabrics are ideal for floor manufacturing because they provide the longest-lasting, most consistent performance.

Luxury vinyl tile manufacturing
Luxury Vinyl Tile (LVT) is a fast growing market with widespread application in both residential and commercial construction. Its durability and aesthetic appeal has given it a competitive edge over traditional flooring options such as ceramic tile and wooden flooring. The LVT base layer substrate is formed through a high-temperature and high-pressure lamination of melt-processable PVC crumb and glass skrim. A specialized 2PLY CHEMFAB® PTFE coated fiberglass belt lines both the bottom and the top of this LVT substrate throughout the lamination process. This high-performance application capitalizes on several properties unique to CHEMFAB belts: an easy non-stick release that enables roll-to-roll processing, high-temperature and chemical resistance during the PVC melt process, and a low profile seam that does not increase thickness or result in mark-off at the belting joint.
Padded and cushion backed flooring
Padded and Cushion Backed Flooring sees application in anti-fatigue mats, therapeutic pads, artificial turf, and traditional carpeting. PVC or PU formulations of mechanical froth and chemically blown foams are metered onto CHEMFAB® PTFE coated fiberglass belts at controlled thicknesses and then cured in an oven. After curing, the padding easily releases without sticking to the CHEMFAB belt and is rolled for post processing. CHEMFAB belts are able to withstand the high temperatures of the curing process and the aggressive chemical foaming agents in the PVC and PU formulations.
Crumb rubber mats manufacturing
Crumb Rubber Mats are commonly seen outside of homes due to their durable weatherproof construction. Recycled automotive tires are processed into a crumb state and are then metered along with a thermoplastic polyurethane (TPU) onto a CHEMFAB® PTFE coated fiberglass belt. This belt is indexed underneath a heated hydraulic press which melts the TPU binder and molds the crumb rubber into the desired mat style. Many times polyester or nylon filaments are then added as a topping to the mat. The intense temperatures and pressures seen during the pressing cycle make CHEMFAB PTFE coated fiberglass belts and ideal choice for this application. Additionally, the easy no-stick release of the TPU binder from the CHEMFAB belt results less production yield loss and damaged mats.
Walk-off mats manufacturing
Walk-Off Mats are ubiquitous throughout industrial and residential settings alike. These mats are traditionally made by laying uncured nitrile onto a CHEMFAB® PTFE coated fiberglass belt; tufted nylon carpet is then placed on top of the nitrile mat. This package is indexed into a static, heated bladder-press that simultaneously bonds the carpet topping to the nitrile rubber and cures/vulcanizes the nitrile rubber.CHEMFAB PTFE coated fiberglass material also lines the bladder press for an easy release after the curing cycle. CHEMFAB material is critical in this application due to the high curing temperatures of nitrile rubber, the clean non-stick release of the bonded mat from the bladder press, and the unique mark-off the woven fiberglass substrate leaves on the bottom and perimeter of the mats.
Heat-setting is a process that prepares a carpet yarn for tufting and weaving. PET, nylon, or polypropylene yarns are oxidized in a humid oven to give them memory, impart additional stain resistance, and to prepare them for the dying process. CHEMFAB® PTFE coated Kevlar open-mesh belts are able to withstand the humid, high-temperature environment as well as the harsh chemical byproducts from the yarn during Heat Setting process.
