1. Valiant PEI Stock Announcement

We are pleased to announce that CISKO NEW MATERIAL has expanded its product portfolio to include the full range of Valiant PEI powders. As an authorized distributor of Valiant polyetherimide (PEI) resins, we now stock four powder grades: VAT002P50, VAT002P100, VAT002P200, and VAT002P350.

These micronized PEI powders open up new manufacturing possibilities for our customers – from additive manufacturing (SLS 3D printing) and compression molding to rotational molding and ceramic injection molding binders. All powders share

1. Flame Retardant Regulations Introduction

Flame retardancy is not a “nice to have” for many engineering plastics – it is a legal and safety requirement. Electrical and electronic (E&E) components, automotive parts, and aerospace interiors must resist ignition, self‑extinguish quickly, and produce low smoke and toxicity in the event of a fire. Failure to comply can lead to product recalls, liability lawsuits, and barriers to market access.

However, the regulatory landscape is complex. Different regions have different standards

1. Introduction PEI vs PEEK

When engineers need a polymer that can withstand sustained heat, resist chemicals, and maintain mechanical integrity, two materials often top the list: PEI (polyetherimide) and PEEK (polyetheretherketone). Both are high‑performance engineering thermoplastics used in aerospace, medical, oil & gas, electronics, and automotive industries. But they are not interchangeable.

PEI, best known under the brand name Ultem™ from SABIC (and also available as Valiant PEI from domestic suppliers), offers an excellent balance

1. Introduction PEI Injection Molding

Polyetherimide (PEI), sold under brand names like SABIC Ultem™ and Valiant PEI, is a high-performance amorphous engineering plastic. It offers exceptional thermal stability (Tg 217°C), inherent flame retardancy (UL94 V0), and excellent mechanical properties up to 170°C. However, these benefits come at a cost: PEI demands precise injection molding conditions.

Unlike commodity plastics like polypropylene or ABS, PEI is hygroscopic and sensitive to moisture, requires high melt and

1. Introduction Ultem PEI in Aerospace

The aerospace industry faces a constant challenge: reduce aircraft weight to improve fuel efficiency while maintaining the highest safety standards. Every kilogram saved on an aircraft can save hundreds of gallons of fuel per year. At the same time, materials used in cabin interiors must be flame‑resistant, produce low smoke and toxicity, and withstand repeated cleaning and temperature fluctuations.

Ultem™ PEI (polyetherimide) from SABIC has emerged as a go‑to engineering plastic
