Excellent Regidity PBT Long Glass Fiber Plastic Injection Molding

What Is It?

PBT Long Glass Fiber Reinforced Composite is engineered with long glass fiber reinforcement (12–25 mm) to deliver superior mechanical strength, dimensional stability, and chemical resistance. It is designed for demanding applications requiring resistance to moisture, heat, and impact—particularly in electrical, automotive, and industrial environments.

Technology Behind the Strength

Long Glass Fiber Architecture

Compared with traditional short-fiber compounds, PBT-LGF utilizes long glass fibers that form an internal reinforcing network during molding. This structure significantly improves impact strength, reduces creep under load, and enhances long-term dimensional stability.

Advanced Pultrusion Process

Manufactured using a controlled pultrusion process, each pellet contains uniformly impregnated long glass fibers, typically 12–25 mm in length. This ensures consistent fiber distribution and reliable mechanical performance in molded components.

Where It Works Best

Optimized for medium-stress, chemically aggressive, and outdoor-use environments.

• Automotive: battery covers, mudguards, underbody shields
• Logistics & Packaging: pallets, foldable boxes, heavy-duty crates, RTP systems
• Construction: formwork panels, drainage systems, outdoor cabinets
• Agriculture: chemical-resistant tanks, mechanical housings, equipment covers
• Consumer Products: garden tools, outdoor furniture bases, structural storage parts
