Conductive & Antistatic Plastics - Xresin (Dongguan) Plastics Co., Ltd.

Plastic polymers have excellent electrical insulating properties. However, this leads to static charge buildup, which can create safety hazards for people and equipment, especially in explosive atmospheres.

We modify base resins with graphite, carbon black, antistatic polymers, fibers and carbon nanotubes to produce conductive compounds, enabling plastic components to be used in environments such as ATEX zones.

Steel-fiber-reinforced compounds provide conductivity and shield electromagnetic radiation up to 60 dB.

Introduction to Conductive Plastics

Conductive plastics are functional polymer materials made by blending a resin base with conductive additives and processed using standard plastic molding methods. In general, materials fall into four conductivity classes: insulators, semiconductors, conductors and superconductors. Conductive plastics span the transition from insulator to semiconductor to conductor, the widest range of change achievable in any material. Compared with traditional materials, they are lightweight, easy to mold and have adjustable resistivity, and they can readily be synthesized or compounded into a wide variety of structures through molecular design. By conductivity, conductive plastics are classified as insulating, antistatic, conductive and highly conductive; by manufacturing method, as intrinsically conductive or filled (composite) conductive plastics; and by application, as antistatic materials, conductive materials and EMI shielding materials.

Base resins include: PC/ABS, PC, ABS, PA, PPE, etc.
Main conductive fibers: nickel-coated carbon fiber, stainless steel fiber, etc.;
Conductive plastics provide both EMI shielding and grounding.

Conductive Plastics - Advantages over Metals

Shielding effectiveness designed to product requirements;
Good corrosion resistance and long service life;
Can produce parts with complex geometries;
No secondary processing, less waste and fast delivery;

Low production losses, lowering production costs
No shielding gaskets needed at seams, cutting assembly time and cost
Low density, reducing shipping costs

Antistatic plastics 10¹⁰ to 10¹¹Ω·cm

These materials provide very slow static charge decay, from hundredths of a second to several seconds, preventing buildup that could become a discharge source or trigger other nearby electrical events.

Xresin conductive materials protect sensitive electronics from the damaging effects of static electricity. These compounds offer a consistent surface resistivity of 10¹⁰ to 10¹¹Ω·cm and contain no carbon black, so they do not crock or slough. Unlike coatings, these properties are inherent to the material and do not depend on humidity for activation or suffer from brittleness.

Static dissipative 10⁶ to 10¹²Ω·cm

Our static dissipative compounds control charge dissipation or decay much faster than antistatic materials, typically within milliseconds. The measured resistance is uniform and generally robust.

Materials offering ideal electrostatic discharge (ESD) protection (10 ⁶ – 10⁹ Ω·cm) sit at the low end of the static dissipative range. Our conductive plastics are developed specifically for ESD protection and are offered in four additive technologies: stainless steel fiber, carbon nanotubes, carbon black and Xresin dissipative polymer technology. Our product line also includes carbon-particle-filled grades.

Conductive plastics 10¹ to 10⁶Ω·cm

These materials provide decay rates measured in nanoseconds — enough to provide a grounding path and dissipate stronger charges.

This conductivity is achieved by adding carbon fiber, high loadings of carbon powder or other conductive additives.

EMI/RFI shielding plastics 10¹ to 10⁴Ω·cm

These materials qualify by more than conductivity alone: they can absorb or reflect electromagnetic energy, so they can shield against sources of interference.

Products with shielding performance are achieved by dispersing stainless steel or metallized fiber fillers
