Static Dissipative & ESD Solutions

Carbon-reinforced engineering plastics designed for controlled electrical conductivity. These stock shapes are engineered to prevent the buildup of static electricity, protecting sensitive semiconductor components and electronic assemblies while providing the high mechanical strength and thermal stability of PEEK, PPS, and Ultem.

Key Highlights

Structural ESD

Unlike dissipative coatings that can wear off, these materials are "conductive through-and-through," meaning the ESD properties remain even after extensive machining or surface wear.

Explosion Safety

Used in fuel handling and chemical processing to prevent static sparks in potentially explosive atmospheres (ATEX environments).

Protection for Sensitives

Essential for semiconductor wafer handling, hard drive assembly, and electronic test fixtures where a single spark could ruin a component.

Non-Sloughing Performance

High-quality carbon fiber and graphite integration ensures that conductive particles do not "shed" or contaminate cleanroom environments during use.

Controlled Resistivity

Formulated to fall within the static dissipative range (10⁶ to 10⁹ ohms/sq) or conductive range (10³ to 10⁵ ohms/sq) to prevent sudden electrostatic discharge.

Frequently Asked Questions

What is the difference between Conductive and Static Dissipative?

Conductive (<10⁵ ohms/sq): Charges move very quickly. Used for grounding and EMI shielding.

Static Dissipative (10⁶ to 10⁹ ohms/sq): Charges move more slowly and controlledly. This is preferred for handling sensitive electronics to prevent "hard" discharges.

Does machining affect the ESD properties?

No. Because the carbon fibers are distributed throughout the entire stock shape, the ESD properties are "bulk properties." Whether you machine deep into a plate or stay on the surface, the resistivity remains consistent.

Are these materials safe for Cleanrooms?

Yes. Carbon-fiber reinforced PEEK and Ultem are considered "low-sloughing." Unlike some low-end carbon-powder filled plastics, these fibers are locked into the resin matrix and will not contaminate high-purity environments.

Can these materials provide EMI/RFI Shielding?

The more conductive grades, such as PPS-CF40 and PEEK-CF30, provide a degree of EMI shielding. However, for high-level shielding, specialized grades with higher carbon or metal content are typically used.
