Anti-static PEEK Granules|Injection Grade

ESD PEEK granules (also known as anti-static PEEK pellets) are carbon-fiber modified compounds engineered for injection molding of semiconductor components. They deliver stable surface resistivity of 10⁶–10⁹ Ω/sq, protecting sensitive circuits from static damage while retaining PEEK's high-temperature strength.
Designed for cleanroom environments, these electrostatic dissipative granules offer continuous service at 260°C and excellent chemical resistance. ESD PEEK is the preferred material for test sockets, wafer carriers, and precision gear systems requiring both EMI protection and structural reliability

Product Description

| Injection Grade Antistatic PEEK Pellets | ESD-Safe & High Performance

ESD-Safe PEEK Granules for Precision Molding

Injection Grade Antistatic PEEK (Polyetheretherketone)granules is a high-performance semicrystalline polymer engineered with permanent ESD control, combining PEEK's exceptional thermal, chemical, and mechanical strength with stable surface resistivity. It is purpose-built for precision injection molding of components where electrostatic safety, high heat resistance, and dimensional stability are critical.

⚡ Permanent Antistatic Performance

ESD PEEK Stable surface resistivity (10⁶–10⁹ Ω/sq), without moisture dependence, protecting sensitive electronics during molding and use.

High-Temp resistance

Continuous service up to 260°C,

️ Chemical & Wear Resistance

Inherently resistant to aggressive fluids and abrasion, ideal for demanding cleanroom and semiconductor environments.

⚙️ Precision Moldable

Low shrinkage and high flow enable tight-tolerance ESD-safe components without post-molding coatings.

✔️ ESD-Safe by Nature: No carbon sloughing or coating degradation.
✔️ Metal-Replacement Capable: Lightweight alternative to aluminum in static-sensitive assemblies.
✔️ Cleanroom Compatible: Low outgassing, chemically inert, and dimensionally stable.

Unique ESD PEEK Formula for Ultra-Clean ESD Protection

Permanently Stable Resistivity Control

Our formula locks surface resistivity in the 10⁶–10⁹ Ω/sq range across continuous operating temperatures up to 260°C, eliminating the risk of sudden electrostatic discharge that can irreversibly damage sensitive electronic components.
Unlike surface-coated ESD solutions, the antistatic property is built directly into the polymer matrix—ensuring lifelong stability even after repeated autoclaving, chemical exposure, or precision machining, with no performance degradation over the component lifecycle.

Zero Particulate Contamination Risk

A defining advantage of our proprietary blend is the complete absence of carbon black fillers or loose particulates. Conventional carbon-filled PEEK grades often shed microscopic carbon debris during handling, injection molding, or end-use—posing critical contamination risks in ISO Class 5 cleanrooms and semiconductor fabs.
PRES ESD PEEK granules produce no sloughing or filler shedding, protecting wafers, ICs, and diagnostic sensors from micro-contamination while meeting strict outgassing and particle generation standards for high-purity processes.

| FAQs – Injection Grade Antistatic PEEK Pellets

Q1: How is antistatic PEEK different from conductive PEEK?

Antistatic PEEK controls surface resistivity in the 10 ⁶–10 ⁹ Ω/sq range, safely dissipating static without sudden discharge. Conductive PEEK (often >30% carbon fiber) is much lower in resistance and better suited for full EMI shielding rather than gentle ESD protection.

Q2: Does the antistatic performance wash or wear off?

No. The antistatic mechanism is built into the polymer matrix itself, so it remains stable over the component's lifetime—even after repeated sterilization, chemical exposure, or machining.

Q3: Is this grade suitable for thin-wall precision molding?

Yes. This injection-grade formulation offers excellent melt flow and low mold shrinkage, making it ideal for thin-wall ESD-safe connectors, test sockets, and micro-sized semiconductor components.
