Fillers for PTFE Compounds
larger image
The unique properties of polytetrafluoroethylene have made it an indispensible material for a broad and growing list of industries and applications. PTFE is the most widely used fluoropolymer. PTFE is a high molecular weight, strong carbon fluorine polymer. This extremely slippery, chemically inert polymer has the lowest coefficient of friction of any solid and is very thermally stable. However, unfilled or virgin PTFE is sometimes an inadequate material for many applications; adding fillers to PTFE results in a fluoropolymer compound with improved properties. When a filler or an assortment of fillers is integrated into PTFE, the result is known as a PTFE compound.
Flontech USA insures the refinement of all of our fillers through such processes as superior sourcing, impurity removal, tight particle size control and laser verification. Our processes guarantee our compounds are only produced with fillers of the most superior quality. Serving a wide array of professional industries such as aerospace, chemical and food processing, and health care, our advanced fillers are equipped with a variety of electrical, mechanical, thermal and tribological properties that help provide improved wear resistance, increased hardness and thermal conductivity, and reduced linear coefficient of thermal expansion and contraction. Generally, PTFE compounds maintain PTFE’s excellent chemical and high temperature characteristics. We also offer pigments in most any color individually or in any combination and percentage customized to your specifications. Flontech USA is interested in meeting your compounding needs by utilizing any and all fillers in any combination and filler percentage. We will also speckle your compounds as well as color match any of your current products.
From bearings and brake pads to clutches, gaskets and hydraulic piston rings, our superior fillers are designed for a vast number of applications and from a wide variety of materials including, but not limited to, aramid, calcium fluoride, graphite, hard or soft carbon and polyphenylene sulphone. If you require a filler material we do not stock, we will special order it for you.
Please inquire today to receive more information regarding our superior fillers and compounds.
