Low Flow Compounds
Low-flow PTFE | PTFE compoundsGemini Pro-Lon supplies both industry-standard and custom low-flow blends to meet precise processing requirements.
Our low-flow compounds are engineered to deliver tight control during molding and compression processes, making them ideal for applications requiring consistent dimensional accuracy and performance. Whether you need glass-filled, carbon-filled, polyimide-filled, or other specialty blends, we offer both standard formulas and custom-tailored PTFE compounds designed to your exact specifications
GLASS-FILLED COMPOUNDS
Glass fiber is the most commonly used filler in conjunction with PTFE resin. These compounds exhibit great dielectric properties, chemical resistance, and greatly reduce creep.
| 95% Virgin PTFE | 5% Glass Fiber |
| 85% Virgin PTFE | 15% Glass Fiber |
| 75% Virgin PTFE | 25% Glass Fiber |
| 60% Virgin PTFE | 40% Glass Fiber |
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 retaining their hardness.
| 90% Virgin PTFE | 10% Carbon |
| 85% Virgin PTFE | 15% Carbon |
| 75% Virgin PTFE | 25% Carbon |
GRAPHITE-FILLED COMPOUNDS
Graphite adds extra lubricity to an already slick PTFE while remaining chemically inert. Wear resistance and a low coefficient of friction help graphite excel as a PTFE filler.
| 95% Virgin PTFE | 5% Graphite |
| 90% Virgin PTFE | 10% Graphite |
| 85% Virgin PTFE | 15% Graphite |
| 75% Virgin PTFE | 25% Graphite |
CARBON/GRAPHITE-FILLED COMPOUNDS
Carbon/Graphite blends excel in chemical and mechanical applications. They add strengthening physicals while reducing initial wear. Displaying high load-carrying capabilities in abrasive contact applications, carbon/graphite compounds also have a very high hardness.
| 75% Virgin PTFE | 23% Carbon | 2% Graphite |
| 70% Virgin PTFE | 15% Carbon | 15% Graphite |
| 67% Virgin PTFE | 30% Carbon | 3% Graphite |
BRONZE-FILLED COMPOUNDS
Bronze excels in adding higher compressive strength, higher thermal conductivity, and lower creep. Several different percentages of bronze can be added to PTFE to gain these properties, but bronze is not recommended for highly corrosive or electrical environments.
| 60% Virgin PTFE | 40% Bronze |
| 40% Virgin PTFE | 60% Bronze |
MOLYBDENUM-FILLED COMPOUNDS
Molybdenum or “moly” is almost always used in conjunction with other fillers, primarily glass or bronze. Additional lubricity, hardness, compression, and wear resistance make Molybdenum an instrumental filler.
| 95% Virgin PTFE | 5% Molybdenum | |
| 75% Virgin PTFE | 5% Carbon | 5% Molybdenum |
| 60% Virgin PTFE | 15% Glass Fiber | 5% Molybdenum |
| 40% Virgin PTFE | 55% Bronze | 5% Molybdenum |
STAINLESS STEEL-FILLED COMPOUNDS
Stainless steel-filled PTFE increases overall strength. High-temperature applications, such as hot liquids or steam, make this filler an excellent choice for the food and beverage industry.
| 50% Virgin PTFE | 50% Stainless Steel (316L) |
POLYIMIDE-FILLED COMPOUNDS
Polyimide is a synthetic polymer that is non-abrasive and performs exceptionally well in dry-running applications. Start-stop or softer surfaces, such as aluminum, brass, or other plastics, are a good match for polyimide-filled compounds.
| 85% Virgin PTFE | 15% Polyimide |
PIGMENTED COMPOUNDS
Pigmented Compounds are a great way to separate PTFE parts visually.
With each lot backed by a certificate of analysis and manufactured to ASTM quality standards, our low-flow PTFE compounds provide the reliability industrial engineers expect. Contact us to explore materials engineered for consistency, precision, and optimal flow behavior in your operations.
