PVC cable materials are engineered formulations designed to meet demanding technical, safety and durability requirements. Through the careful selection of additives, PVC compounds can provide electrical insulation, mechanical protection, fire safety performance and long service life across a wide range of cable applications.
The European PVC cable value chain continuously develops cable formulations to improve performance, safety and environmental compatibility, while ensuring compliance with European regulations.
Tailored Material Performance
PVC cable compounds consist of PVC polymer combined with selected additives that enable specific performance characteristics required in cable applications.
These formulations allow manufacturers to adjust properties such as:
- electrical insulation performance
- flexibility and mechanical strength
- resistance to temperature and environmental exposure
- fire and smoke behaviour
- durability over long service life
Responsible Use of Plasticisers
Plasticisers are used in flexible PVC cable compounds to provide the flexibility required for installation, handling and long-term performance.
Over the past two decades, the European PVC industry has implemented significant changes in plasticiser technology. Through the VinylPlus programme, the value chain has progressively replaced low molecular weight (LMW) phthalates with alternative plasticisers.
Today, flexible PVC cable formulations in Europe use:
- high molecular weight phthalates
- non-phthalate alternatives, including polymeric and ester-based plasticisers
Research and development continues in the field of bio-based plasticisers, supporting further innovation in sustainable PVC formulations.
Other Additives in PVC Cable Formulations
In addition to plasticisers, PVC cable compounds include other additives that contribute to performance and durability.
These may include:
- stabilisers to ensure long-term material stability
- additives supporting fire performance
- fillers to optimise mechanical and processing properties
- lubricants and processing aids
The selection of these additives depends on the specific cable application and required performance characteristics.
Innovation in Additive Technologies
The European PVC cable value chain continues to develop additive systems to improve environmental compatibility and support circularity.
This includes:
- development of bio-based plasticisers and alternative additive solutions
- optimisation of formulations to support recycling and circular use of PVC
- technologies enabling the identification and management of legacy additives in recycled materials
These developments are supported through collaboration within the VinylPlus framework.
Compliance with European Safety Standards
PVC cable compounds used in Europe are developed in accordance with European regulatory frameworks, including REACH, ensuring a high level of protection for human health and the environment.
Formulations produced within the European VinylPlus value chain are designed to avoid substances of very high concern (SVHC) and reflect a continuous improvement approach to material safety and performance.
