lft-g PA66 reinforced material long glass fiber 30% specification Polyamide66 modified plastic

What is PA66?

PA66 (Polyamide 66), also known as Nylon 66, is a semi-crystalline thermoplastic widely used in automotive, electrical, electronic, and industrial applications. It offers excellent mechanical strength, wear resistance, and thermal stability.

What is PA66-LGF?

PA66-LGF (Long Glass Fiber Reinforced Nylon 66) is a modified engineering plastic made by reinforcing PA66 with long glass fibers. This significantly improves mechanical performance, dimensional stability, and heat resistance.

Compared with unfilled PA66, LGF-reinforced PA66 offers:

• Higher strength and stiffness
• Improved dimensional stability (low warpage and shrinkage)
• Better fatigue and creep resistance
• Reduced water absorption impact on properties

Material Characteristics

• High mechanical strength and rigidity
• Excellent heat resistance and wear resistance
• Good chemical resistance (oils, fuels, greases)
• Low friction and self-lubricating properties
• Stable performance under humid and variable environments

Applications

1. Automotive Industry

Used in engine covers, intake systems, cooling components, interior and structural parts such as dashboards, door handles, and brackets.

2. Electrical & Electronics

Applied in connectors, switches, insulation parts, housings, and electrical components requiring flame resistance and dimensional stability.

3. Industrial & Machinery

Suitable for gears, bearings, fasteners, conveyor parts, and structural mechanical components requiring high strength and durability.

Product Specification

FAQ

1. Is higher glass fiber content always better?
Not necessarily. The optimal fiber content depends on application requirements such as strength, toughness, and surface quality.

2. Can LGF materials be used for appearance parts?
Yes, but surface quality must be evaluated based on product design and mold conditions.

3. How to choose reinforcement length?
Selection depends on required mechanical performance and final application conditions.
