Bost PEEK Plastic Gasket Solutions for High-Performance Sealing
Bost PEEK Plastic Gasket — High Quality Sealing for Demanding Environments
Bost’s PEEK plastic gaskets combine polymer science and precision manufacturing to deliver seals engineered for the most challenging conditions. Made from high-performance PEEK (polyether ether ketone), these gaskets offer superior thermal stability, excellent chemical resistance, and exceptional mechanical strength, making them ideal for high-temperature, high-pressure, and corrosive service.
Performance Benefits of PEEK Plastic Gasket
PEEK plastic gaskets provide continuous service temperatures up to ~250°C, outstanding dimensional stability, low creep, and excellent fatigue life. Their low friction and wear resistance extend seal life in dynamic applications. Bost enhances these baseline properties with targeted modifications — improved toughness, flame retardancy, and conductive/thermal variants — to meet industry-specific demands.
Applications and Industry Use
Designed for critical sectors such as aerospace, oil & gas, chemical processing, automotive, and power generation, Bost PEEK plastic gaskets excel where standard materials fail. They resist harsh chemicals, steam, and oils while maintaining sealing integrity under cyclical loads, making them a preferred choice for valve seats, flange gaskets, compressor seals, and electrical insulator interfaces.
Customization and Manufacturing Strength
Bost is a professional and innovative high-tech green energy engineering plastics manufacturer specializing in R&D, production, and sales. Our capabilities include custom compound formulation, precision mold design, machining of sheets and rods, and composite steel-plastic assemblies. We tailor PEEK gasket thickness, hardness, and surface finishes to match installation and performance requirements.

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
How do I select the appropriate engineering plastic grade for my product?
Selection should be based on parameters such as load conditions (e.g., pressure/friction), temperature range, medium contact (e.g., oil/acid), and regulatory requirements (e.g., FDA/RoHS). Our engineers can provide free material selection consulting and sample testing.
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.
