Conductive PVC compound is a composite material with conductive properties made from polyvinyl chloride (PVC) as the base material by adding conductive fillers and other substances. Carbon black and carbon nanotubes are the fillers most commonly used. This guide covers the RenJie® SA series of graphene conductive PVC — including the SA 509C grade developed for PVC ESD cable — together with the hardness range, performance characteristics and application fields of PVC conductive compounds.

1. What Is a PVC Conductive Compound?

A PVC conductive compound is a polymer composite material in which conductive fillers are dispersed in a polyvinyl chloride matrix. The filler forms a conductive network inside the PVC, so the finished part dissipates static charge instead of insulating it. Because the base material is PVC, the compound keeps the familiar processing behaviour, flexibility and formulation versatility of PVC while adding controlled electrical performance.

Permanent antistatic performance — the conductive network is built into the compound, not applied as a surface coating.

Flame retardant, V-0 rated — suitable for applications with strict fire-safety requirements.

Environmentally friendly with low VOC — reduced emissions for enclosed and clean environments.

Hardness range from 85 A to 60 D — covering flexible to semi-rigid ESD protection applications.

Ready for injection molding and extrusion — usable on standard PVC processing equipment.

Customizable properties — other performance requirements can be tailored to customer demand.

2. RenJie® SA Series Graphene Conductive PVC

The SA series of graphene conductive PVC is a group of polymer composite materials developed by RenJie®. The product mainly combines PVC and graphene materials to give PVC new electrical, thermal and mechanical strength properties, increase the added value of PVC and expand the application fields of PVC. Carbon black grade, carbon nanotube grade and graphene-reinforced grade are available. The SA series is suitable for injection molding and extrusion, and is RoHS and REACH compliant.

3. Application Fields of PVC Conductive Compound

3.1 Antistatic Packaging for the Electronic Industry

PVC conductive compounds are widely used for antistatic and electromagnetic shielding packaging of electronic products. They prevent static electricity from damaging sensitive electronic components. In the packaging of integrated circuits, semiconductor chips and similar products, conductive PVC materials can effectively dissipate accumulated static electricity and protect the performance and reliability of electronic components.

3.2 Electromagnetic Shielding and Compatibility

Conductive PVC can be used to make electromagnetic shielding materials that shield the electromagnetic radiation generated by electronic equipment and reduce interference with the surrounding environment and other equipment. Using conductive PVC materials in the shells, cable sheaths and other parts of precision electronic instruments improves the electromagnetic compatibility of the equipment.

3.3 Industrial Field: Conductive PVC Floors

Conductive PVC floors are widely used in industrial environments that are sensitive to static electricity, such as electronic manufacturing workshops, pharmaceutical factories and operating rooms. This kind of floor can promptly guide away the static electricity generated by the human body and equipment, and prevent static sparks from causing fires or explosions.

3.4 Industrial Field: Conductive PVC Conveyor Belts

In material conveying systems that require antistatic performance, conductive PVC conveyor belts avoid problems such as material adsorption, blockage or spark discharge caused by the accumulation of static electricity.

3.5 Automotive Field

Some automotive parts use conductive PVC ESD materials to reduce the accumulation of static electricity in the car and improve riding comfort and safety — for example car seat covers and foot mats.

3.6 Special Working Environments

In workplaces that require antistatic protection, such as the petrochemical industry and the production of flammable and explosive goods, the work clothes worn by workers may use PVC ESD materials to prevent danger caused by static electricity.

4. Filler Systems for Conductive PVC: General Comparison

Note: the table is general guidance for filler selection only. The final grade, hardness and conductivity should be confirmed by testing the actual part, because the result depends strongly on the compounding and dispersion process.

5. Selecting and Processing a PVC Conductive Compound

Grade selection follows three questions: the electrical requirement (antistatic dissipation versus full conductivity), the flexibility requirement (which determines where the hardness sits between 85 A and 60 D), and the processing method (injection molding or extrusion). The SA series supports both injection molding and extrusion on standard PVC equipment.

Because processing parameters depend on the grade, the hardness and the specific equipment, they are not fixed here. Please refer to the grade TDS or contact the RenJie® technical team for the recommended temperature profile, drying and screw configuration for your machine.

7. Frequently Asked Questions (FAQ)

What is a PVC conductive compound used for?

It is used wherever static electricity has to be controlled: antistatic and electromagnetic shielding packaging for electronic products, ESD cable, conductive floors and conveyor belts in industrial environments, automotive ESD parts such as seat covers and foot mats, and antistatic workwear for petrochemical and flammable-goods production.

What is the difference between the carbon black, carbon nanotube and graphene grades?

The difference is the filler system. Carbon black is the established, cost-efficient route; carbon nanotubes deliver the highest conductivity per unit of filler; graphene-reinforced grades combine PVC with graphene and other carbon materials to add electrical, thermal and mechanical strength properties at the same time. All three are available in the RenJie® SA series for injection molding and extrusion.

What is SA 509C designed for?

SA 509C is modified by graphene and other carbon materials and features outstanding conductive and antistatic performance. It is specially designed for PVC ESD cable applications, and its other properties can be customized according to customer demand.

What hardness range do the PVC ESD compounds cover?

The hardness of the PVC ESD compounds ranges from 85 A to 60 D, covering flexible to semi-rigid ESD protection applications.

Are the RenJie® SA series grades RoHS and REACH compliant?

Yes. The SA series is RoHS and REACH compliant.

Can the properties of the compound be customized?

Yes. In addition to the standard conductive and antistatic behaviour, other properties can be customized according to customer demand — including hardness, flame retardancy, colour and specific electrical targets.
