Strong-Ty™ Cable Ties with Kynar® PVDF: unchanged after long-term UV exposure
Wire and cable management on the photovoltaic backplane is critical for safety and electrical production continuity. Why jeopardize an entire array installation with cable ties made from substandard materials? Even behind photovoltaic panels, polyamide and polyethylene cable ties will fail in reflected UV radiation. It’s only a question of time.
Arkema, the manufacturer of Kynar® PVDF, has completed a 10,000-hour Xenon arc accelerated weather exposure. The results show that all versions of Kynar Flex® have very little change in either tensile strength or elongation and show that Strong-Ty cable ties are the most UV resistant cable ties available today.
This long-term exposure to UV builds on a more than 50-year exposure history of Kynar 500® to sunlight in a south Florida testing center. Video showing test results from this ongoing study can be seen here. Strong-Ty™ cable ties are made from 100% Kynar® PVDF and provide the maximum UV resistance for PV wire and cable management. Available in a natural color, Strong-Ty™ cable ties do not require the addition of carbon black or UV inhibitors to provide long-term dependable outdoor performance.
Strong-Ty™ Cable Ties: long-term UV resistance made possible by Kynar® PVDF
Current 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 UV exposure, temperature extremes and high humidity. These materials are used in cable ties because they are cheap and by themselves are not UV resistant. The possibility of failure makes system-wide inspections of cable ties 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: Kynar® PVDF provides superior performance compared to other cable tie polymers
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.
Strong-Ty™ Cable Ties: Kynar® PVDF satisfies 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?
Strong-Ty™ Cable Ties: chemical resistance that you require
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 cable tie application involves aggressive chemical exposure at elevated temperatures, you need Kynar® PVDF. 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.
