Product Description

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

Injection Grade Antistatic PEI (Polyetherimide), often branded as Ultem, is an amorphous, high-performance thermoplastic offering an outstanding combination of inherent flame retardancy, high rigidity, and long-term dimensional stability. Engineered with permanent ESD protection (10⁸–10⊃1;⁰ Ω/sq), these pellets provide a cost-effective alternative to PEEK for precision molded components requiring electrostatic safety and continuous service up to 170°C.

⚡ Permanent ESD Control

Stable surface resistivity without carbon black blooming, protecting sensitive electronics during automated handling.

Inherent Flame Retardancy

UL94 V-0 rated without additives. Low smoke generation and oxygen index >47%, ideal for aircraft interiors.

️ Chemical & Hydrolysis Resistance

Resists automotive fluids, hot water, and steam. Excellent for under-hood components and sterilization.

⚙️ High Flow & Precision

Exceptional melt flow characteristics allow complex, thin-wall molding with tight tolerances.

✔️ Metal Replacement: High strength-to-weight ratio reduces system costs.
✔️ Food & Medical Grade: Compliant with FDA and USP Class VI standards.
✔️ Colorable: Natural amber tone can be pigmented to custom colors.

| Antistatic PEI Pellets Applications & Use Cases

| FAQs – Injection Grade Antistatic PEI Pellets

Q1: How does Antistatic PEI compare to PEEK in terms of cost?

Antistatic PEI offers significant cost savings compared to PEEK while maintaining high heat resistance (up to 170°C) and inherent flame retardancy. It is the preferred choice for applications where extreme chemical resistance of PEEK is not required but ESD safety and structural rigidity are essential.

Q2: Can PEI be sterilized for medical applications?

Yes. PEI is highly resistant to hydrolysis and can withstand repeated sterilization cycles, including autoclaving (steam), gamma radiation, and EtO (ethylene oxide) gas, making it ideal for reusable medical devices.

Q3: Is PEI naturally flame retardant?

Absolutely. Unlike many plastics, PEI possesses inherent flame retardancy due to its chemical structure. It achieves a UL94 V-0 rating without the need for halogenated additives, resulting in low smoke generation and toxicity.
