Product Information

Product Overview

Bost Machined PTFE Corrosion-Resistant Sealing is a precision-manufactured sealing solution designed for demanding industrial environments. Made from High Quality PTFE and produced by Bost, a leading green-energy engineering plastics manufacturer, these seals combine chemical resistance, low friction and stable performance across a wide temperature range.

Key Benefits

Corrosion and Chemical Resistance

PTFE resists most acids, alkalis and solvents, making these seals ideal for chemical processing, marine, and corrosive media applications.

Low Friction and Wear Resistance

Excellent self-lubricating properties reduce wear and extend service life. The machined surface ensures consistent contact and reduced leakage.

Wide Temperature Range

Reliable performance from cryogenic conditions up to high operating temperatures, suitable for diverse industrial systems.

Applications

Common uses include valve seats, pump seals, flange gaskets, bearing liners and custom components in chemical plants, oil & gas, water treatment, food processing and power generation.

Q&A

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.

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

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.
