Product Information

Product Overview

Bost Corrosion & Wear Resistant Sealing delivers high-performance sealing materials designed to withstand aggressive chemicals, heavy abrasion and long-term mechanical stress. Made by Bost, a professional high-tech green energy engineering plastics manufacturer, this sealing solution combines advanced material modification with durable manufacturing to meet demanding industrial needs.

Key Benefits

Outstanding Corrosion Resistance

Formulated to resist acids, alkalis and many solvents, these seals protect equipment in chemical processing, marine and oil & gas applications — extending service life and reducing downtime.

Superior Wear Performance

With ultra abrasion-resistant and high fatigue durability, Bost sealing parts reduce friction and wear. They are ideal for moving parts such as pump seals, valve seats, bearings and wear pads.

High Temperature & Dimensional Stability

Stable under elevated temperatures, our materials maintain sealing performance where ordinary plastics fail. They also machine precisely into sheets, rods and custom profiles for exact fits.

Question you may concern

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.

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.

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 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.
