    • 常见问题
      Q
      What are the key advantages of PEI compared to other engineering plastics?

      PEI offers outstanding heat resistance (up to 180–200°C continuous use), excellent mechanical strength, dimensional stability, and inherent flame retardancy (UL94 V-0 rated). Unlike standard plastics such as PP or PE, it maintains performance under extreme conditions.

      Q
      Is PEI safe for food and medical applications?

      Yes. Certain PEI grades comply with FDA and ISO 10993 biocompatibility standards, making them suitable for food-contact parts, sterilizable labware, and medical devices. Always confirm grade certification with your supplier.

      Q
      Can PEI be customized in terms of size, color, and properties?

      Absolutely. We provide tailor-made dimensions, surface finishes, reinforced grades (glass/carbon fiber), and even custom colors. Fabrication services like CNC machining, thermoforming, and welding are also available.

      Q
      How does PEI perform in high-temperature environments?

      PEI retains mechanical integrity and electrical insulation at elevated temperatures up to 200°C, making it ideal for automotive, aerospace, and electronic applications.

      Q
      What industries commonly use PEI?

      PEI is widely used in aerospace, automotive, medical devices, electronics, food processing, and chemical processing equipment where high-performance materials are required.

      Q
      Is PEI resistant to chemicals and sterilization?

      Yes. PEI demonstrates excellent resistance to hydrolysis, alcohols, and cleaning agents, and can withstand repeated autoclave sterilization without significant property loss.

      Q
      How is PEI supplied and delivered?

      We offer PEI in sheets, rods, and customized components. Orders are packed in protective export packaging with flexible logistics options to meet global delivery needs.
