Wire & Cables

From polymer electronical performance to flame resistance and heat transfer, our diverse portfolio meets the complex and challenging demands of wire and cable applications.

Due to their high carbon content, plastics are highly combustible. Using flame retardants can significantly lower the risk of fire, but they do also have some disadvantages too as they can modify the polymer properties of the material. This can often cause the required mechanical or electrical properties to be ineffective.

However, to counter act these tendencies, our innovative additives based on our organically modified siloxanes are available. Flame retardancy is becoming increasingly important, especially in the transportation and construction sectors where the Construction Products Regulation (CPR) specifies new standards for cable applications in construction. The intention is to prevent fire from spreading, for example through cable shafts.

Our TEGOMER® V-Si 4042 and TEGOMER® FR 100 products have enabled the development of suitable HFFR cable compounds – without adversely affecting the material properties.

Another example is the EN 45545 standard for transportation applications: For safety reasons, regular EPDM-based rubber is being increasingly replaced in railway cars by silicone rubber using TEGOSIL® FR 1000.

In e-mobility, in electronics and in electrical systems, flame protection is critical – for wire and cables, switch cabinets, casting compounds for components, etc. Even just a minimal amount of additive from Evonik can make a key contribution to a better performance. Here our TEGOMER® H-Si 6441 P has become the product of choice for applications in high-performance plastics such as PA, PBT or TPE.

Using the right additives can not only mitigate the disadvantages of flame retardants but can significantly help you to meet further industry and legislative requirements – such as minimal smoke formation and low heat release rates in the event of a fire.
