CISKO NEW Material Expands Valiant PEI Stock – Now Offering VAT002P50, P100, P200, P350 Powders
| May 27, 2026
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 the same high-performance characteristics as Valiant’s injection molding grades: a glass transition temperature (Tg) of 217°C, inherent flame retardancy (UL94 V0), excellent dielectric properties, and outstanding thermal stability.
Whether you need fine powder for intricate 3D‑printed parts or coarse powder for cost‑effective bulk molding, we have a solution for you. Read on to learn about the specifications, applications, and how you can request samples or volume quotes.
2. Why PEI Powders?
PEI powder forms are used in several advanced manufacturing processes where pellets are not suitable. Here are the most common applications:
2.1 Compression Molding of Large, Simple Shapes
For large parts (e.g., aircraft interior panels, electrical insulators, medical trays), compression molding of PEI powder can be more economical than injection molding. The powder fills a heated mold cavity under pressure, then sinters into a solid part. This process requires no complex injection machine and can produce near‑net shapes with minimal waste.
2.2 Rotational Molding of Hollow Parts
Hollow parts such as ducts, tanks, and housings can be rotationally molded using PEI powder. The powder is placed inside a mold that rotates biaxially while heated; the powder melts and coats the inner surface, forming a seamless, stress‑free part.
2.3 Binder for Ceramic Injection Molding (CIM)
In ceramic injection molding, PEI powder can be used as a binder system. When mixed with ceramic powders, PEI provides excellent green strength and burns out cleanly during sintering, leaving a defect‑free ceramic part.
2.4 Additive Manufacturing (Laser Sintering / SLS)
Selective laser sintering (SLS) 3D printing of PEI is an emerging technology for producing high‑temperature, flame‑retardant prototypes and low‑volume production parts. The fine particle size (especially VAT002P50 with D50 50 µm) allows for smooth layers and high resolution. Parts printed from Valiant PEI powder exhibit mechanical properties close to injection‑molded PEI.
3. Product Specifications
The table below summarizes the four grades, their particle sizes, typical applications, and pricing.

| VAT002P100 | D50 = 100 µm | 50.20 | Compression molding, rotational molding, ceramic binder, general‑purpose powder |
| VAT002P200 | D90 = 200 µm | 38.80 | Large part compression molding, filler for polymer blends, cost‑effective |
| VAT002P350 | D90 = 350 µm | 37.00 | Coarse powder for bulk molding, low‑cost applications, where fine detail not required |

4. Key Properties of Valiant PEI Powders
Valiant PEI powders retain the same outstanding properties as their pelletized counterparts. Here are the key characteristics:
| Property | Typical Value | Test Method |
|---|---|---|
| Glass transition temperature (Tg) | 217°C | DSC |
| Density | 1.27 g/cm³ | ISO 1183 |
| Tensile strength (after sintering) | ~110 MPa | ASTM D638 |
| Flexural modulus | ~3,300 MPa | ASTM D790 |
| Notched Izod impact | 7.0 kJ/m² | GB/T 1843 |
| Flammability | UL94 V0 (≥0.75 mm) | UL 94 |
| Dielectric strength (1.6 mm oil) | 21.1 kV/mm | IEC 60243-1 |
| Volume resistivity | >1.0×10¹⁶ Ω·cm | IEC 60093 |
| Oxygen index (LOI) | 47% | ASTM D2863 |
Key advantages of powder form:
- No need to melt and pelletize – directly processable.
- Excellent flowability and packing density.
- Consistent particle size distribution (PSD curves available).
- Retention of mechanical properties after sintering (tensile strength ~110 MPa, same as molded PEI).
All Valiant PEI powders are REACH and RoHS compliant, and do not contain PFAS or halogenated flame retardants.
5. Case Example
Background: A medical device manufacturer needed to produce radiolucent surgical trays for use in X‑ray and fluoroscopy procedures. Traditionally, they machined these trays from PEEK blocks. The process was slow (CNC machining time of 45 minutes per tray), generated significant waste, and the material cost was high.
Challenge: Reduce cost and lead time while maintaining radiolucency, sterilizability (autoclave), and strength.
Solution: The manufacturer switched to compression molding of Valiant VAT002P100 powder.
Process:
- The powder was pre‑dried at 150°C for 4 hours.
- A measured amount was placed into a heated mold (170°C).
- The mold was closed under pressure (10 MPa) and held for 20 minutes, allowing the powder to sinter.
- The part was cooled under pressure and then removed.
Results:
- Cost reduction: The raw material cost of Valiant PEI powder was approximately 40% lower than PEEK block. Machining waste was eliminated, saving an additional 15%.
- Lead time: Compression molding cycle time was 25 minutes per tray (including heating and cooling) – almost half the machining time.
- Performance: The trays passed autoclave testing (134°C, 100 cycles) and remained radiolucent. Mechanical strength met or exceeded requirements.
Outcome: The customer switched entirely to compression‑molded Valiant PEI trays, saving over $50,000 annually.
