Product Information

Overview

Bost Overmolded Tight Sealing is a precision-engineered sealing solution designed for demanding environments. Combining our expertise in modified engineering plastics with advanced overmolding techniques, this product provides reliable, long-lasting seals that minimize leaks and maintenance.

Key Features

Tight, Long-Term Sealing

Overmolded construction bonds plastic directly to metal or other substrates, eliminating gaps and weak interfaces. The result is a consistent, tight seal that resists aging and mechanical fatigue.

Durability and Chemical Resistance

Formulated for high corrosion and abrasion resistance, the material stands up to oils, fuels, solvents, and harsh industrial media. It maintains performance over repeated cycles and in abrasive conditions.

High-Temperature Stability

Bost’s modified plastics offer excellent thermal resistance for applications exposed to elevated temperatures, ensuring dimensional stability and seal integrity over time.

Customizable and Compatible

We provide tailored formulations and geometries to meet OEM requirements. Our materials can be adapted for bonding to metals, rubbers, and other plastics, enabling multi-material assemblies with improved performance.

Benefits for Your Application

Reduced leakage and downtime
Longer service life compared with standard seals
Strong resistance to chemicals, abrasion, and heat
Easy integration in existing production lines and assemblies
Custom design support and scalable manufacturing

Typical Applications

Bost Overmolded Tight Sealing is ideal for automotive fuel and fluid systems, electrical connectors, industrial valves, medical device housings, outdoor equipment, and any assembly needing reliable, compact sealing.

Question you may concern

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.

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.
