Plastics solve problems and they can overcome issues that plague traditional materials such as metals and wood. But for the most part a plastic still has some weak spots that under certain situations can create a trade-off in properties: the optimal material but not perfect. Redco Tuffkast; however, is our material with the fewest weak points and therefore can solve problems that other plastics simply cannot.
Tuffkast is most commonly a replacement for nylon in areas where nylon suffers deficiencies: water absorption, impact, and low-temperature performance. In each case Tuffkast’s properties are superior to nylon: it absorbs much less water, is an excellent impact and low-temperature material. This means in applications where nylon is commonly used Tuffkast can be substituted, applications such as bearings and sheaves. To reduce the coefficient of friction, Tuffkast is available in both oil-filled and dry lubricant grades. Tuffkast has excellent wear abilities and impact resistance that is over double that of nylon.
Any drawbacks to Tuffkast are minimal. It does have a higher cost than many plastics of the engineering-grade tier but this is offset by its excellent performance. The higher coefficient of friction than materials it replaces (such as UHMW) needs to be considered but again, this can usually be offset by getting one of the lubricant filled grades. In general, Tuffkast is an extraordinarily versatile engineering plastic that is able to solve many problems other plastics simply cannot. For more information on Redco Tuffkast please contact us.
