High Temperature Resistance PPA Long Glass Fiber Plastic Injection Molding

What Is It?

PPA composite, reinforced with continuous long glass fibers for superior mechanical strength, excellent dimensional stability, and outstanding chemical and thermal resistance. Engineered for demanding environments where performance under heat, load, and aggressive media is critical.

Technology Behind the Strength
1. Continuous Fiber Architecture
Unlike traditional short fiber materials, our PPA-LGF incorporates long glass fibers aligned along the flow direction during molding. This internal structural reinforcement significantly enhances tensile strength, impact performance, and fatigue resistance — even under prolonged thermal stress.

2. Precision Pultrusion Process
Each pellet is produced using a controlled pultrusion process, ensuring uniform fiber length (typically 12–25 mm) and optimized fiber distribution. This consistency translates to better mechanical performance, especially in structural and high-precision parts.

Where It Works Best
Tailored for use in extreme environments, where high heat, chemical exposure, and dimensional stability are essential. Applications include:

Automotive:
Turbo air ducts, charge air coolers, electronic component housings, clutch actuator components

Industrial Equipment:
Pump housings, valve bodies, high-performance brackets, process connectors

Electrical & Electronics:
Connectors, sensor housings, circuit protection components

Energy Sector:
Battery module frames, insulating structural components, fuel cell parts

Aerospace & Rail:
Lightweight structural panels, mounts, clips with flame-retardant and low warpage requirements

Performance Highlights

Tailored for Your Needs
We don’t believe in one-size-fits-all. Our PP-LGF compounds can be modified to suit:

Flame retardancy (94-V0)

UV stabilization for outdoor use

Color-matched aesthetics

Conductive or anti-static performance
