ARAMID FIBER COMPOUNDS - RTP Company

1 Manufacturing Facilities:Winona, MNSouth Boston, VADayton, NVBeaune, FranceFort Worth, TXIndianapolis, INImagine a thermoplasticcompound designed specificallyfor parts that move and wearagainst surfaces such as brass,aluminum, bronze, glass,ceramic, and other plasticcomponents. One that is creepresistant, dimensionally stable,and avoids plate out whenmolded. At RTP Company , wenot only imagined it, we made ita FIBER COMPOUNDS (AFC s) are made with aromaticpolyamide FIBER , commonlyknown as Twaron or Kevlar.

2 Unlike glass and carbon FIBER , ARAMID is softer and less abra-sive. This is a major advantagein wear applications, particularlyif the mating surface is sensitiveto and molders chooseAFC s over metals to minimizecosts, reduce weight, lowernoise, and ensure corrosionresistance. AFC s are also self-lubricating, lowering the coeffi-cient of friction and extendingthe life of mating Headquarters:RTP Company580 East Front StreetWinona, MN 55987phone: 507-454-6900800-433-4787fax: 507-454-4629web site: : FIBER COMPOUNDSS uperior Wear-Resistant Thermoplastics From RTP CompanyQuick InformationMinimize Abrasion to Counter/Mating SurfacesImprove Wear ResistanceReduce Coefficient of FrictionTypical applications include.
