填充玻璃與未填充尼龍：完整的性能比較

Adding glass fibers to nylon dramatically changes its performance characteristics. While unfilled nylon offers excellent toughness and processability, glass-filled grades deliver substantially higher strength, stiffness, and thermal stability.

What Is Glass-Filled Nylon?

Glass-filled nylon is a composite material consisting of nylon resin reinforced with short glass fibers. The most common grades contain 15%, 25%, 30%, or 50% glass fiber by weight.

Mechanical Properties Comparison

尺寸穩定性

Glass fibers reduce the material’s coefficient of linear thermal expansion (CLTE) by 50-70%, bringing it closer to metals like aluminum.

處理注意事項

Glass-filled nylon requires: higher melt temperatures, higher injection pressures, hardened molds due to abrasive wear, and careful gate design for fiber orientation.

Cost Considerations

GF30 provides the best balance of cost and performance for most applications. It’s the most widely used glass-filled grade.

Application Guide

Choose Unfilled Nylon When:

• Impact resistance and toughness are critical
• Parts need good surface finish
• Snap-fits or living hinges are required
• Cost is the primary concern

Choose Glass-Filled Nylon When:

• High strength and stiffness are needed
• Dimensional stability under heat is critical
• Metal replacement is the goal
• Precision tolerances must be maintained
