Glass Filled Compounds

Glass fiber is the most common filler compounded with PTFE resin. These compounds exhibit great dielectric properties, chemical resistance, and greatly reducing creep.

All glass filled compounds can be pigmented upon request.

Carbon Filled Compounds

Carbon blends offer much less abrasiveness compared to glass, as well as higher impact strength in mechanical applications. They also perform well in electrical and thermal insulation environments while greatly retaining hardness.

Graphite Filled Compounds

Graphite adds extra lubricity to an already slick PTFE while keeping chemically inert. Wear resistance and a low coefficient of friction help graphite excel as a PTFE filler.

Carbon/Graphite Filled Compounds

Carbon/Graphite blends excel in chemical and mechanical applications. They add strengthening physicals while adding reduction to initial wear. Displaying high load carrying capabilities in abrasive contact applications carbon/graphite compounds also have a very high hardness.

Bronze Filled Compounds

Bronze excels in adding higher compressive strength, higher thermal conductivity, and lowers creep. There are several different percentages of bronze that can be added to PTFE to gain these abilities, but bronze is not recommended for high corrosive, or electrical conditions.

Molybdenum Filled Compounds

Molybdenum or “moly” is almost always used with other fillers, primarily glass or bronze. Additional lubricity, hardness, compression, and wear resistance make Molybdenum a very useful filler.

Stainless Steel Filled Compounds

Stainless steel filled PTFE increases overall strength. High-temperature application such as hot liquids or steam makes this filler an excellent choice for the food and drink industry.

Polyimide Filled Compounds

Polyimide is a synthetic polymer that is non-abrasive and performs excellently in dry running applications. Start-stop or softer surfaces like aluminum, brass, or other plastics are a good match for polyimide filled compounds.

Pigmented Filled Compounds

Pigmented Compounds are a great way to visually separate PTFE parts.
