OUR PREMIUM MATERIAL PORTFOLIO
High-Performance Engineering Plastics
We provide the ideal high-temperature polymer solutions tailored to your specific operating environment. Whether your project requires extreme thermal stability, biocompatibility, or superior chemical resistance, our engineering-grade resins (PEEK, PPSU, PEI) ensure reliable performance under the most demanding conditions.
- PEEK (Polyetheretherketone): High strength, heat resistance up to 260°C, and exceptional wear resistance.
- PPSU (Polyphenylsulfone): Superior impact strength and repeated steam sterilization capability (Medical Grade).
- PEI (Polyetherimide): Excellent dielectric strength and flame resistance (UL94-V0) for electronics.
- PPS (Polyphenylene Sulfide): High-dimensional stability and incredible chemical resistance in harsh environments.
- PSU (Polysulfone): Transparency and high-temperature performance for food-grade and plumbing applications.

Do you have questions for our services?
We’ve compiled answers to some of the most frequently asked questions about our special engineering plastic raw materials. If you don’t see your question here, feel free to contact us directly.
For standard grades of PEEK, PPSU, and PEI, our MOQ is as low as 25kg (one bag) to support your initial testing and small-batch production. For customized color matching or reinforced compounding, the MOQ typically starts from 100kg-500kg depending on specific requirements.
Absolutely. As a direct factory in Dongguan, we specialize in functional compounding. We can customize materials with specific reinforcements like carbon fiber, glass fiber, or PTFE lubricants to meet your precise mechanical, thermal, or electrical performance needs.
We follow strict ISO 9001 standards. Each batch undergoes rigorous in-house testing for melt flow index (MFI), density, and mechanical properties. Every shipment is accompanied by a Certificate of Analysis (COA) and a Technical Data Sheet (TDS) to ensure 100% consistency.
Yes. Our materials are exported to over 30 countries, including the Europe, USA, and Southeast Asia. We are fully compliant with RoHS, REACH, and FDA regulations. Our team provides professional English communication and all necessary documentation for smooth customs clearance and compliance.
