Glasgevuld vs Ongevuld Nylon: Volledige Prestatievergelijking

Glass-Filled vs Unfilled Nylon is a common design decision when balancing stiffness, impact behavior, and molding performance.

For GF15, GF30 and higher reinforcement levels, use our glass-filled nylon grade guide; this page focuses on whether reinforcement is needed in the first place.

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.

Vergelijking van mechanische eigenschappen

Dimensionale stabiliteit

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

Verwerkingsoverwegingen

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.

Gebruiksaanwijzing

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

Welke soorten nylonkunststof kunnen voor dit project op maat worden gemaakt?

Nylon Plastic combineert materiaalaanpassing met productontwerp, matrijsontwerp en -bouw, spuitgieten, CNC-bewerking en 3D-printen. De juiste toepassing wordt bepaald op basis van de tekening en de gebruiksomstandigheden, en niet op basis van een algemene materiaalbenaming.

Van beoordeling tot productie

1. Definitie: de tekening, de toepassing, de omgeving en het volume delen.
2. Recensie: vergelijk risico’s op het gebied van materiaal, proces, DFM en validatie.
3. Valideren: Maak waar nodig gebruik van monsters, 3D-printen, CNC-bewerking of prototypegereedschap.
4. Producten: de gereedschappen of de productie pas vrijgeven nadat de overeengekomen controles zijn afgerond.

Where PA6-GF20 Fits in the Selection

Buyers often compare only unfilled nylon with a 30% glass grade, but the intermediate loading can be the better production choice. PA6-GF20 is worth evaluating when an unfilled grade deflects or shrinks too much, while the cost, brittleness, surface texture, fiber orientation, or tooling burden of a higher loading is not justified.

Decision	Unfilled PA6	PA6-GF20	PA6-GF30
Primary reason to select	Toughness, fatigue, wear, and surface quality	Balanced stiffness, shrinkage control, and moldability	Higher stiffness and lower directional shrinkage
Typical tradeoff	More deflection and moisture-driven movement	Moderate anisotropy and visible fiber texture	More warpage sensitivity, brittleness, abrasion, and cost
Validation focus	Conditioned fit, creep, and impact	Gate direction, weld lines, warpage, and conditioned dimensions	Flow orientation, local stress, tool wear, and critical surface acceptance

Compare the exact matrix and grade in the expected moisture condition. A PA6-GF20 result should not be substituted directly for PA66-GF20, and a headline dry tensile value should not replace molded-part testing. For a higher loading, review the PA6-GF30 product route; for a different reinforcement family, use the PA6-CF30 route only when its specific stiffness or other qualified benefit is required.

Veelgestelde vragen

Can the glass-fiber loading be customized for the part?

The team can review different reinforcement levels, but the choice should be tied to deflection, impact, warpage, flow length, appearance and tool wear rather than selecting the highest percentage by default.

Is unfilled nylon better for snap fits and impact?

Often it is because unfilled nylon generally retains more ductility. The correct answer depends on beam strain, conditioning, wall thickness, assembly cycles and the exact resin grade.

Can color and surface finish be controlled on glass-filled nylon?

Color and mold texture can be reviewed, but exposed fibers and flow orientation may limit the achievable appearance. Identify cosmetic zones and approved reference samples in the RFQ.

What information is needed for a filled-versus-unfilled review?

Send the CAD and drawing, current grade, load and environment, critical fits, appearance target, annual volume and any existing failure or warpage data.
