Companies are increasingly considering PFAS-free cables for their industrial applications for reasons of environmental protection, compliance, and supply chain risk management. While PFAS are high-performing, they are also extremely persistent and potentially harmful to health. Many companies are therefore opting for more sustainable alternatives in the long term, also to protect themselves against potential future restrictions.
In this context, RADOX® is the ideal solution: all RADOX® cables are PFAS-free; furthermore, they guarantee superior technical performance in terms of thermal and chemical resistance as well as reliability. Below, you will learn how to eliminate PFAS from your cables without compromise.
Why PFAS influence cable selection
PFAS (or per- and polyfluoroalkyl substances) are very stable synthetic chemicals: they repel water and oils, are heat-resistant, and resistant to aggressive agents. Due to these properties, they are used in many industrial applications. In the world of cables, they are mainly found in specific fluoropolymers such as PTFE and ETFE. Their high thermal, chemical, and electrical resistance makes them particularly suitable for sectors like aerospace, medical technology, and industrial automation.
However, their high stability is a significant problem: PFAS tend to accumulate in the environment and in organisms, posing potential health risks: they can affect the liver, thyroid, and immune system, and increase the risk of cancer.
European and international regulations regarding the use of PFAS are becoming increasingly strict to drive innovation and the replacement of these compounds. As a result, the electrical cable sector is also looking for PFAS-free alternatives that can ensure operational continuity and compliance without the need to redesign systems. However, the PFAS content is not always declared, and it can be difficult to find alternatives that do not compromise the durability, cost, or certification of the component.
All RADOX® cables are PFAS-free
RADOX® cables use cross-linked XLPE/XLPO compounds (cross-linking through irradiation) that do not contain PFAS. The classification as PFAS-free applies to all product lines, including RADOX® 125, RADOX® 155, and the UL-approved versions: UL 3266, UL 3289, and UL 3680.
Companies already using RADOX® cables are thus aligned with potential regulatory developments and ESG goals. For companies currently using fluorinated cables, RADOX® cables represent a reliable and high-performance alternative. The transition to a PFAS-free solution, with technical support from Miotti during selection, protects against future regulatory measures and strengthens the company’s ecological and social commitment.
Technical performance without compromise
Thanks to the superior properties of RADOX® cables, switching to PFAS-free solutions does not affect performance. The main advantages include:
- Cross-linking through irradiation ensures dimensional stability and thermal resistance even under critical conditions;
- Reliability over time with fewer system downtimes and reduced maintenance efforts;
- Availability of UL approval and documentation upon request;
- High chemical and mechanical resistance in harsh environments (including in oil with the RADOX® UL 3680 model);
- Miotti acts as a Global Distribution Hub for RADOX® cables, with stock availability, fast delivery times, and individual technical consultation.

Application examples: How the transition takes place
In a system operating at temperatures up to 155 °C, with possible immersion in oil and the need for mechanical robustness, an ETFE cable is a common choice. In such cases, RADOX® UL 3680 is the ideal alternative: it is PFAS-free, designed for harsh environments, and has UL approval (Style 3680: 150 °C – 600 V – Oil & Gasoline resistant). The switch requires an application review and correct electrical dimensioning but maintains the design philosophy.
Another common scenario involves material harmonization: the quality department demands PFAS-free cables for all new orders, while the technical department fears the impact on service life and reliability. The RADOX® portfolio covers class B (125 °C) and F (155 °C) with equivalent products. It is therefore possible to plan the transition: first the new projects, then—where appropriate—the retrofitting of existing systems, while maintaining performance and continuity of supply.
How to choose the right PFAS-free RADOX® cable
These transitions are not always simple. At Miotti, we support our customers with individual consultations in selecting the right RADOX® cables for every application. We start with some preliminary questions:
- What is the actual operating temperature (continuous and peak)?
- What environment does the cable operate in (oils, chemicals, humidity, vibrations, thermal cycles, etc.)?
- What compliance requirements does the application have (internal standards, target market, approvals)?
Based on this, we define the cross-section, installation, and current-carrying capacity and check availability. Furthermore, as a Global Distribution Hub, we can shorten delivery times thanks to the availability of stock and fast delivery times.
Frequently Asked Questions About PFAS-Free RADOX® Cables
Why should I choose PFAS-free cables?
Eliminating PFAS is a proactive choice: it reduces the risk of having to act quickly in the event of future restrictions and meets ESG requirements. Furthermore, the damage that PFAS cause to the environment and people is extensively documented (the film Dark Waters is recommended on this topic). So why not choose an alternative solution with the same performance?
Can I replace fluorinated cables immediately?
In most cases, yes. For all Class B (125 °C) and Class F (155 °C) cables, we offer an immediately available alternative product with equivalent properties and completely PFAS-free. The typical example is the replacement ETFE → RADOX® UL 3680 for environments with oils and temperature peaks.
What documentation can I receive?
We provide technical data sheets, safety data sheets for all cables, and an official declaration of absence of PFAS if required for qualification and audits.
