The Fluorinar™ Kynar® PVDF Filament Family Expands
Nile Polymers is pleased to announce the addition of two new filaments in the Fluorinar™ PVDF family: Fluorinar-B™ and Fluorinar-ESD™. Both materials are built on a foundation of Arkema’s Kynar® PVDF. Unlike other PVDF filaments, Fluorinar™ filaments contain no additional polymer additives or diluents. They provide the best available chemical resistance and high-temperature performance, Kynar® PVDF standards for more than 50 years. All of the Fluorinar™ filaments have additional material qualities such as UV protection, high strength, flame suppression, toughness and flexibility. Because both filaments are based on Fluorinar-C™, outstanding build plate adhesion and zero warping provide a dependable and repeatable printing experience.
Fluorinar-B™ is a black-colored print filament which combines the dependability of Kynar® PVDF with our Fluorosmooth™ adhesive. Fluorosmooth™ increases the surface energy of the printed part at the interface with the glass build plate. This results in improved bond strength between the printed part and the build surface. Removal of a Fluorinar-B™ print must be done very carefully in order to not damage the glass build plate. The presence of carbon pigment increases the tensile strength and permeation resistance of the final part.
Fluorinar-ESD™ is our new graphene-enhanced electrostatic dissipation (ESD) filament made with Kynar® PVDF. This material is an excellent choice for applications that cannot tolerate static build-up on the printed part. Fluorinar-ESD™ has all of the advantages of Kynar® PVDF combined with the ease of printing associated with Fluorinar™. Our filament carefully calibrates melt viscosity and impact strength so that the final part is both strong and durable. The surface conductivity of printed parts is measured at 2 x 10-5 ohm meters.
Sample filaments are available for both Fluorinar-B™ and Fluorinar-ESD™. We invite you to try these new materials on your next project. Additional information about our Fluorinar™ PVDF filaments and PVDF in general can be found on the following pages:

Strong-Ty™ Solar Cable Ties: unchanged after long-term UV exposure
Wire and cable management on the photovoltaic backplane is critical for safety and electrical continuity. Why jeopardize an entire PV installation with cable ties made from substandard polymers such as nylon and polyethylene? Even behind photovoltaic panels, nylon and polyethylene cable ties fail in reflected UV radiation and exposure to zinc chloride. It’s only a matter of time. Start out with the right solar panel cable tie and avoid problems later on. Our Strong-Ty™ solar panel cable tie with Kynar® PVDF is designed for long-term harsh environments.
Purisan™ PVDF Chemical Mixers: thick coated shaft with injection molded blades
For many applications PVDF coatings provide a high purity surface while eliminating corrosion problems. However, a completely coated mixer is not the optimal material choice. Consider the leading edge of impeller blades. During daily use this surface comes in contact with the solution and all that it contains. Powder coating along the leading edge of the impeller are prone to rapid wear and exposure of the metal substrate leading to process contamination and mixer failure.
Purisan™ Kynar® mixers lead the way in custom mixing assemblies
Before Purisan™ Kynar® mixers were available, ordering a high-purity or corrosion resistant mixer was painful process. First you called a mixer company, who manufactured the shaft and impeller. They delivered the completed to a coating company who prepared the surface and applied the coating. All of these steps take time and together create the two plus month delivery schedule typical in this industry. Want to shorten the lead time? That’s an expedited order and will cost extra!
Single-Use Mixer: key component in pharmaceutical manufacturing
Disposable bag technology is important in minimizing cost and contamination in biopharm production. When mixing is required, Purisan™ Kynar® PVDF single-use mixers can be incorporated directly into the bag prior to gamma sterilization. The Kynar® PVDF prop is injection molded and threads onto a Kynar® PVDF coated shaft. The final mixer is cleaned, assembled and packaged in a clean room following ISO 13485 certified procedure.
The Nile Polymers Fluorostretch™ fluoroelastomer has passed ISO 10993 cytotoxicity testing. Patented by DuPont almost 60 years and sold under the Viton® tradename, the FKM fluoroelastomer is a PVDF and HFP Type I copolymer as defined in the ASTM D1418 standard. Fluorostretch™ fluoroelastomer plays an integral part in the Purisan™ PVDF mixers by preventing contamination and corrosion in the threads which join the powder coated stainless steel shaft with the injection molded impeller.
Strong-Ty™ PVDF Cable Ties: long-term UV resistance made possible by Kynar®
Photovoltaic (PV) arrays have a 25-year plus life expectancy. However, the nylon and polyethylene cable ties can fail in a matter of months due to combinations of UV, temperature extremes, zinc chloride corrosion and high humidity. Commodity cable ties provide no dependable long-term solution for wire and cable management in PV arrays. The reality of a commodity cable tie failure makes system-wide inspections a constant requirement in order to prevent ground fault failures.
Strong-Ty™ Cable Ties: sterile cable ties made with Kynar® PVDF
Strong-Ty™ PVDF cable ties can be sterilized by gamma radiation without any negative effects to material properties. The result is a cable tie ready for high purity applications in single-use pharmaceutical manufacturing or medical device equipment.
Strong-Ty™ Cable Ties: superior performance with Kynar® PVDF
The most common plastics used to manufacture cable ties are polyethylene, polypropylene, and nylon. These commodity plastics can come from thousands of sources including original manufacturers, compounders, and recyclers. Often the point of origin is price dependent and can change with each production run. While these cable ties are inexpensive, their performance in critical applications is inadequate and prone to failure.
The Kynar® PVDF used in Strong-Ty™ cable ties is manufactured by Arkema and comes from only a single source. Consider the following Strong-Ty™ PVDF cable tie properties:
Strong-Ty™ Cable Ties: Kynar® PVDF meets international regulations
Concerns about material safety and traceability are more important than ever as cable ties made from inferior materials flood the market. In mission-critical applications polymer substitution or manufacturing shortcuts are unacceptable. How confident are you in your current cable tie? What materials, including additives, stabilizers, fillers, plasticizers and regrind are part of your final cable tie product? Are all of these components acceptable and can you trace each of them back to the point of origin?
We choose to make our Strong-Ty™ cable ties from Kynar® PVDF and have never looked back. Kynar® PVDF offers a wider range of chemical resistance compared to other polymers. When your application involves aggressive chemical exposure at elevated temperatures, you need Strong-Ty™ chemical resistant cable ties. The following chart from Arkema shows the corrosion resistant properties of PVDF compared with commodity plastics such as polypropylene, polyvinylidene chloride, polyvinyl chloride, and polyester. Because they are made from Kynar® PVDF, our cable ties can be fully traced back to the point of manufacture.
Kryptonar™ Powder: high purity PVDF coating system
Kryptonar™ PVDF sets a new industry standard for extractable metal ions in a partially fluorinated polymer. Results from metal ion extraction testing at Balazs Labs using the Semi F57 procedure look very good. Your final products are only as good as your powder coating material so when you need to be clean, choose Kryptonar™ powder for your high purity PVDF coating and eliminate the contamination.
