Bost PEI Plastic Gasket: High-Performance Engineering Seals
Bost PEI Plastic Gasket — Advanced Sealing for Demanding Environments
Why Choose PEI Plastic Gasket
PEI plastic gasket from Bost combines superior mechanical strength with excellent thermal and electrical insulation. As a green-energy-focused engineering plastics manufacturer, Bost delivers PEI gaskets that perform reliably under continuous high temperatures, aggressive chemicals, and repeated mechanical cycles. Our PEI plastic gasket is ideal where long service life and dimensional stability matter.
Key Performance Features
Our PEI gaskets offer ultra-high temperature resistance, outstanding creep and fatigue performance, low moisture absorption, and excellent dielectric properties. The material resists corrosion, abrasion, and aging — making PEI plastic gasket an outstanding choice for critical sealing tasks in harsh conditions. The result is reduced maintenance, longer replacement intervals, and improved system uptime.
Manufacturing & Customization
Bost integrates advanced polymer modification, mold design, and precision machining to produce sheets, rods, and finished gasket parts. We enhance toughness, flame retardancy, and thermal conductivity through dedicated R&D, enabling tailored PEI plastic gasket solutions in custom shapes, tolerances, and surface finishes. Production supports tight tolerances for bolt-hole alignment, flange sealing faces, and molded profiles.
Typical Applications
PEI plastic gasket from Bost is widely used in aerospace seals, electrical insulators, high-temperature valves, chemical processing equipment, and energy infrastructure. Wherever high heat, electrical isolation, or chemical exposure exists, a Bost PEI gasket provides reliable sealing and insulating performance for demanding industrial and green energy systems.
Bost Advantage & Next Steps
Bost combines high technical expertise, full-spectrum production capability, and responsive service to meet custom requirements quickly. We deliver quality-assured PEI plastic gasket products that meet regulatory and performance standards. Contact Bost to discuss specifications, request samples, or start a project — our team will recommend the optimal PEI gasket solution for your application.

What are the core advantages of Bost engineering plastics compared to ordinary plastics?
Bost engineering plastics feature ultra-high mechanical strength, high-temperature resistance (-50°C to 300°C), chemical corrosion resistance, and wear resistance. Compared to ordinary plastics, their service life is extended by 3 to 8 times, making them suitable for replacing metals in harsh environments.
What is the minimum order quantity (MOQ)? Do you support small-batch trial production?
The MOQ for standard products is ≥100kg. We support small-batch trial production (as low as 20kg) and provide mold testing reports and performance data feedback.
What is the delivery lead time? Do you offer global logistics?
Standard products: 5–15 working days; custom modifications: 2–4 weeks. We support global air/sea freight and provide export customs clearance documents (including REACH/UL certifications).
Can Bost customize modified plastics with special properties?
Yes! We offer modification services such as reinforcement, flame retardancy, conductivity, wear resistance, and UV resistance, for example:
• Adding carbon fiber to enhance stiffness
• Reducing the coefficient of friction through PTFE modification
• Customizing food-grade or medical-grade certified materials
