PTFE & Teflon Molded Cylinders

Fluoro-Plastics compression molds cylinders for machining in a wide range of sizes. The most common sizes are listed in the table below, but many other combinations of OD and ID are available. Molded cylinders are preferred for machining because compression molding yields greater material homogeneity for the finished part.

Most cylinders are molded to 12 inches in length, although other lengths are available.

All cylinders can be etched for bonding, and can be mounted on a plywood disk for less waste in machining.

All cylinders can be made with filled (reinforced) PTFE to enhance the performance parameters of PTFE. Materials available for reinforcement are Glass Fiber, Carbon, Graphite, Bronze, Molybdenum Disulfide, and Stainless Steel.

PTFE GLASS-FILLED COMPOUNDED

  • Thickness .020"
  • Width 12"
  • Length 12"
Various fillers can be added to PTFE to enhance certain characteristics, e.g. Glass fiber (high wear resistance, good electrical, low friction), graphite (low friction, excellent chemical resistance, high creep resistance), carbon fiber (high wear resistance, high load resistance, high bend resistance), glass fiber and Molybdenum Disulfide (high wear resistance, low friction, high creep resistance), Bronze (high wear resistance, heat dissipation). In some industries filled PTFE has become the standard, such as the bearing pad industry, where various percentages of glass fiber are added to the base PTFE resin to create an extremely tough, weatherproof, interface material which can be cut or stamped into configurations to match the dimensions of the opposing surfaces. Fluoro-Plastics has been producing compounded PTFE products and shapes since compounding was invented. Tell us about your application problem and let Fluoro-Plastics' half century of experience work for you. Conforms to ASTM D 4745.

Teflon Sheet

  • Thickness 3/32"
  • Width 12"
  • Length 12"
  • Material Type Standard PTFE
Skived sheet can be made in any thickness from 15 mils up to .250 inches. Fluoro-Plastics technology makes it possible to make in-between sizes. Thickness tolerances range from .0005 for sizes from .002" thick to .005" thick up to .003" tolerance for material that is over .060" thick. Skived sheet is ideal as a slide surface, for chute liners, other kinds of liners, or for cutting or stamping into gaskets (asbestos substitute) and diaphragms, including complex stamped gasket configurations. It comes in sheets from 60 inches by 60 inches square to rolls 60 inches wide. Standard sizes are 48 inches square, twelve inches square, twenty-four inches square, thirty-six inches square, and rolls one, two, three and four feet wide are available for clicker press fabricators. Material may be ordered in long lengths as individual sheets. The material can be wound on a three inch cardboard or PVC core: All interim thickness sizes are available on special order, and rolls may be silt to interim widths. All material conforms to ASTM D3308. Material is white. The material may be ordered etched for bonding on one or both sides for an additional charge (both Sodium Ammonia and Sodium Naphthalene etching are offered).

Rectangular Bars

Fluoro-PlasticsSurf Technologies stocks standard guide rail shapes: cover bar, chain guide, snap-ons, half rounds, and j legs in various sizes for applications where temperatures exceed 180 deg. F. All shapes are extruded from granular PTFE, which is the toughest kind of PTFE and is ideal in conveyancing systems to quickly and easily move products and materials with no breakage, reduced chatter and noise and little downtime on the line. Virgin PTFE is FDA approved. It is non-stick, has zero water absorption, withstands corrosives, is non-aging, easy to cut, machine and install, and has good flexibility and a long service life. PTFE guide rails and wear strips will operate in the harshest chemical environments and in temperatures from -350 deg. F to over 500 deg. F, making them ideal for food processing, sterilization applications, chemical processing industries, cosmetics industry and many other high-tech industries where products have to travel over or along metal rails through harsh environments at high temperatures. PTFE guide rails and wear strips will provide thousands of hours of continuous, economical service where all of the melt-processible plastics fail. Standard lengths are 5 feet and 10 feet, but non-standard lengths are available. Fluoro-Plastics stocks an extensive array of rectangular bar sizes for use as a slide surface in ways and slots.
