Turcite B® is a thermoplastic resin used in industrial applications to reduce friction on moving parts and bearings. It is resistant to chemical corrosion and self-lubricating. Trelleborg Sealing Solutions produces variations of the resin, including Turcite A® and Turcite X®. Linear motion bearings are often treated with it for free movement in one direction. It has a minimum tensile strength of 2,000 PSI and an elongation before failure of 170%.
Turcite B® is the trade name for polytetrafluoroethylene, a thermoplastic resin used in industrial applications that require the reduction of friction on moving parts and bearings. It is made of sheet metal, is resistant to chemical corrosion and is self-lubricating. Common chemical compounds often used to replace this product include Delrin AF® and Rulon 142®. Delrin AF® is the trade name of polyoxymethylene formaldehyde polymer and Rulon 142®, which has the same chemical composition as Turcite B®, is prepared as a blue-green solid plastic, with the addition of some metal compounds such as copper, tin , zinc and more. Metals such as chromium and bronze can often be added as fillers to increase their strength and thermal properties.
The name is a trademark of Trelleborg Sealing Solutions of Fort Wayne, Indiana, a manufacturer of mechanical friction parts, plastics, bearings, and other components designed to reduce friction in various applications. Trelleborg also produces other variations of this resin, including Turcite A®, a plastic designed for heavy loads and can be easily machined. Another variation is Turcite X®, designed for low-load, high-speed applications, making it less wear resistant than Turcite A® but able to withstand extended temperatures of 180°F (82°C) .
Trelleborg Solutions has had an exclusive partnership since 1995 with a company known as Machine Tool Specialty Components. They apply this product in a friction sealing program known as the Busak Shamblan Turcite B® Slydway® system. Machine Tool Specialty Components is located in Waukesha, Wisconsin and services manufacturing companies throughout the United States, Mexico and Canada.
The friction solutions provided by the thermoplastic resin operate specifically in a linear dimension. This means that bearings or slides treated with it are designed to provide free movement in one direction only. Linear motion bearings are often employed in factory environments where roller guides are used to move products from one station to another and can be motorized or non-motorised.
As an industrial thermoplastic, Turcite B® has a minimum tensile strength of 2,000 pounds per square inch (PSI) and an elongation before failure of 170%. At a hardness level of 50-60, it falls in the soft end of the range for hard thermoplastics. It also shows greater ability to resist peeling and wear in standardized tests than its primary, albeit less expensive competitor, Rulon 142®.
