Tailored PTFE Blends | Custom PTFE Formulations

Gemini Pro-Lon specializes in custom PTFE compounds, offering specialty and proprietary blends for diverse industries.

Our world-class blending operation ensures high-performance materials tailored to meet specific application requirements.

At Gemini Pro-Lon, we understand that standard PTFE compounds may not always meet the unique demands of every application. Our custom compounding services allow you to select from a variety of fillers, including milled fiberglass, carbon, graphite, molybdenum, bronze, polyimide, stainless steel, and pigments, to create a PTFE blend that aligns perfectly with your performance, thermal, and chemical requirements. Whether you need enhanced wear resistance, reduced friction, or specific color coding, our team is equipped to develop a formulation that delivers optimal results. Backed by ISO 9001:2015 certification and rigorous testing, our custom compounds provide the reliability and precision your projects deserve.

Here’s some helpful information along with a custom compounding form so you can select your own PTFE compound for a quote.

Milled fiberglass is the most common filler and is widely used across nearly all industries.

Glass enhances PTFE by improving wear resistance, reducing creep, and increasing compressive strength. Standard milled glass comes in 1/32” strands, and all glass is treated in-house to prevent oxidation that can affect appearance.

Carbon improves compression, wear resistance, and has very good thermal conductivity.

There are several grades of carbon on the market, from activated carbon to coke flour, and even carbon fiber. Carbon fiber compounds are excellent for reducing creep while still bolstering the advantages of carbon itself. Carbons are a lot of times used with graphite for even better wear and friction properties.

Graphite improves PTFE’s lubricity and reduces wear.

This flaky crystalline form of carbon further lowers the coefficient of friction and can enhance electrical conductivity. It is often combined with carbon or glass when these additional properties are desired.

Molybdenum is primarily used in lowering the coefficient of friction and wear resistance.

Moly has a crystal structure similar to graphite, but unlike graphite, it is an excellent lubricant under extreme pressures. Molybdenum can be added directly to PTFE, though it is often combined with bronze or glass formulations. Multiple grades of molybdenum are available, please inquire for details

Stainless steel is ideal for food and beverage applications requiring high strength and purity at elevated temperatures. 316L stainless steel is typically blended 50% with PTFE to meet these demands.

Pigments are mainly used for color coding and part identification.

A full color spectrum can be applied, and we welcome customers to collaborate with us on custom colors to make your machined parts stand out.
