PA compounds for cable extrusion
Promyde® and Proxylene offer a range of PA6 and PBT polymers specifically developed for the extrusion of both internal and external cable jacketing, providing optimum protection for cables manufactured with our polymers.
Another important application of Promyde PA6 is the production of flexible and corrugated tubes for electrical conduits used to protect cables in cars, lorries, trains and industrial machinery.
Air tubes and air-conditioning systems require mechanical resistance at low temperatures, UV and heat resistance in extreme temperature environments over time, as well as flexible properties. These applications require highly sophisticated extrusion compounds.
MEETING THE STRICTEST REQUIREMENTS
- Compliance with stringent European rail standards EN 45545-2
- Resistance to breakage at extreme temperatures
- Thermal stability for optimum performance on the move and under temperature
- Suitable for indoor and outdoor use
POLYAMIDE FOR CABLE EXTRUSION
Our high viscosity Promyde range, with its exceptional impact resistance, strength, high toughness at extreme temperatures, low abrasion, high process performance, good electrical insulation and chemical resistance properties, is the ideal material to achieve high durability of polyamide cable sheathing.
The most common cable applications include nautical cables, fiber optic cables as well as THHN, THWN and TFFN cables.
Cable extrusion benefits
Promyde PA6 provides consistent wire thickness in the most critical processes such as micro and millimeter extrusions. Promyde can be modified to suit indoor and outdoor applications with different performance requirements in extreme temperature environments, stationary and moving mechanical environments.
CORRUGATED PIPING SYSTEMS
Small and large diameter pipes are often produced by corrugated extrusion. Thanks to the use of our range of products Promyde drive systems benefit from added flexibility and optimal protection.
PROMYDE FOR ELECTRICAL CONDUITS
Promyde can be used in extrusion processes for the production of electrical conduits that combine properties of flexibility, mechanical performance and heat resistance so that vehicle electrical systems can operate in varying climatic conditions without technical problems.
HIGH VISCOSITY PBT GRADES
Proxylene B97 P2 is a high viscosity PBT grade with good processability for the extrusion of optical fiber tubes, cables, pipes and profiles.
Proxylene B97 P2 is used in a wide range of applications where a combination of mechanical properties, thermal resistance and dimensional stability are needed.
UL QMTT8 certification for Wire & Cable in Canada
At NUREL, we anticipate international regulatory requirements to provide high-performance technical solutions for manufacturers of cables and cable management systems. Our B33 L UV HS polyamide grade, part of the PROMYDE® range, has obtained UL QMTT8 certification for cable jacketing applications in the Canadian Wire & Cable market, under file number E498368.
This certification is particularly relevant in view of the regulatory transition scheduled for 30 May 2027, after which QMTT2 materials will no longer be accepted for certified cable products intended for use in Canada.
With B33 L UV HS, NUREL offers a polyamide designed for demanding cable sheathing and protection applications, delivering stability against UV radiation and heat, mechanical resistance and good processability in extrusion.

Aplications
Optical fiber cable
Optical fiber cables are crucial in modern telecommunications. NUREL has developed a specific range of Proxylene (PBT) to reinforce and protect the delicate optical fibers within the cable. We also offer special grades of Promyde PA6 for optical fiber cables with high impact resistance requirements.
Cable jacketing
At NUREL, we provide heat-resistant, UV-stable and even flame-retardant polyamide and PBT compounds for the production of cables, wires and cable protection.
Corrugated pipes
Promyde B33 is commonly used for corrugated pipes of this diameter, and Promyde B36 and B38 for larger diameters.
Pipes and Tubes
Promyde® PA6 is widely used in pipe extrusion due to its exceptional strength, durability, and ability to withstand extreme temperatures, corrosion, pressure, and chemical resistance. Additionally, the Promyde PA range offers flexible grades specifically for this type of application.
