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 materials? 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.
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™ 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.
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:
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.
