High Toughness PA12 Long Glass Fiber Plastic Injection Molding

What Is It?

PA12 composite, reinforced with continuous long glass fibers for enhanced toughness, dimensional stability, and low moisture absorption. Engineered for demanding applications where flexibility, chemical resistance, and long-term mechanical performance are essential.

Technology Behind the Strength
1. Continuous Fiber Architecture
Compared to short fiber materials, our PA12-LGF utilizes long glass fibers aligned during molding. These fibers form a continuous reinforcement network within the polymer matrix, significantly improving impact strength, fatigue resistance, and structural integrity over time.

2. Advanced Pultrusion Process
Each pellet is produced using a controlled pultrusion process, ensuring consistent fiber length (typically 12–25 mm), uniform fiber distribution, and optimal bonding between fiber and resin. This results in more predictable mechanical properties and reduced warpage.

Where It Works Best
Tailored for applications where traditional PA12 or other engineering plastics fall short under mechanical or environmental stress.

Automotive:
Fuel system components, connectors, low-temperature flexible parts

Industrial:
Pipe fittings, pneumatic system parts, flexible brackets, housings

Energy & Electrical:
Cable glands, insulating housings, battery module parts

Sporting Goods & Consumer Applications:
