Product Description

Product Overview

Bost PEEK plastic gaskets are precision-engineered sealing solutions made from High Quality polyether ether ketone (PEEK). Designed for demanding environments, these gaskets offer outstanding temperature stability, chemical resistance, and long-term dimensional reliability. Ideal for industries that require dependable seals under pressure, heat, or harsh chemicals.

Key Benefits

High temperature performance: maintains shape and sealing ability across wide temperature ranges.
Chemical and corrosion resistance: resists acids, solvents and aggressive media for extended life.
Exceptional wear and fatigue resistance: reduces replacement frequency and maintenance costs.
Low creep and excellent dimensional stability: ensures consistent sealing under load and time.
Customizable sizes and profiles: tailored to fit specific equipment and application needs.

Typical Applications

Bost PEEK gaskets are widely used in oil & gas, chemical processing, aerospace, automotive, power generation, and semiconductor equipment. They perform well in pump housings, flanges, valves, heat exchangers, and other critical sealing points where failure is not an option.

Q&A

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 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 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.
