* Customisation of pellet grades (flow, reinforcement, colour, masterbatch) to fit your specific needs.
* Industry-grade manufacturing systems geared for high-performance materials.
* Access to high-end application markets such as special engineering plastics, elastomers, and fluoroplastics.
Accordingly, when you partner with us as your PEI Pellets Manufacturer, you get much more than just raw resin — you get engineered, application-ready pellet feedstock.
Polyetherimide (PEI) is an amorphous high-performance engineering thermoplastic characterised by excellent mechanical strength, high thermal stability, flame-retardancy, and good electrical insulation. As a dedicated PEI Pellets Manufacturer, we convert PEI resin into pellet form (granules) that serve as feedstock for injection moulding, extrusion, 3D printing filament fabrication and other downstream processes.
Pellets provide uniform, controlled sized granules that ensure:
* Consistent melt behaviour and processing stability.
* Easier handling, metering and feeding in manufacturing lines.
* Better dispersion when filled or reinforced.
* Reliable downstream dimensional accuracy in finished parts.
When you source from a specialised PEI Pellets Manufacturer, you gain the benefits of tailored melt flow, filler reinforcement and quality assurance built into the pellet feedstock.
As a leading PEI Pellets Manufacturer, we offer a wide portfolio of pellet grades to suit varied processing demands and end-use specifications.
Our baseline grade includes pure, unfilled PEI pellets — ideal when you require the inherent properties of PEI without added fillers. These pellets feature:
* Glass transition temperature around 215-217 °C.
* Long-term use temperature up to around 170-180 °C, short-term up to 200 °C.
* Excellent flame retardancy (UL94 V-0) without added flame-retardant modifiers.
These unfilled pellets are suited for injection moulding, extrusion of precision parts, and applications where high purity and long-term stability are critical.
For higher load-bearing, dimensional-critical or structural components, we offer glass-fibre filled PEI pellets. These reinforce the base resin, delivering:
* Increased rigidity and strength.
* Lower creep over extended use at elevated temperatures.
* Enhanced dimensional stability under mechanical load.
As a trusted PEI Pellets Manufacturer, we can supply GF10%, GF20%, GF30% (glass fibre) fill levels depending on your specification.
When the application demands maximum stiffness, wear resistance or specific functional properties (e.g., conductive, ESD), our specialty grades deliver. These include:
* Carbon-fibre reinforced PEI pellets for extreme modulus and lightweight structures.
* Conductive/ESD PEI pellet platforms engineered for electronics or high-voltage equipment.
Our capabilities as a PEI Pellets Manufacturer extend to custom filler blends, colour masterbatches and additive systems to meet your design goals.
As a full-service PEI Pellets Manufacturer, we enable:
* High-temperature stable colour matching for pellet form and downstream processing.
* Private-label services and custom branding of pellets.
* Tailored flow characteristics, melt-index optimisation or pellet geometry adjustment to suit automation or robotic feeding systems.
As your dedicated PEI Pellets Manufacturer, our product offers a range of technical advantages:
* With a Tg around 217 °C and short-term use beyond 200 °C, PEI pellets support high-temperature applications.
