Product Information

Product Overview

Bost High-Temp Resistant Overmolding is a High Quality overmolding solution designed for components that must endure elevated temperatures, repeated thermal cycles, and harsh environments. Backed by Bost’s expertise in advanced engineering plastics, this product combines heat stability, wear resistance, and strong adhesion to metals and polymers.

Why it’s special

Unlike standard overmolding materials, Bost’s formula maintains flexibility and strength at high temperatures while resisting abrasion, chemicals, and UV exposure. It reduces part failures, improves lifespan, and keeps performance consistent where ordinary plastics degrade.

Key Benefits

High temperature resistance: Stable mechanical properties at elevated temperatures.
Excellent adhesion: Bonds reliably to metals, plastics, and rubber for robust parts.
Superior wear and corrosion resistance: Extends service life in tough conditions.
Enhanced fatigue durability: Minimizes cracking and delamination under repeated stress.
Customizable: Available in different hardness levels, colors, and formulations to match application needs.

Typical Applications

Ideal for connectors, handles, automotive components, industrial tools, electrical housings, and any parts exposed to high heat or harsh environments. Especially suitable where long-term reliability and safety are critical.

Frequently Asked Questions

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).

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.

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.
