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

How to use this table: The existing values are broad screening examples, not one named PA6 grade or a design specification. The table does not state specimen conditioning or complete test methods. For approval, compare current datasheets for the exact unfilled and glass-filled grades under matched conditions, then test molded samples.

Dimensionale stabiliteit

Glass reinforcement can reduce thermal expansion and molding shrinkage along the flow direction, but fiber orientation makes the result direction-dependent. Compare the exact grade’s parallel and transverse values, gate layout and molded-part dimensions before setting tolerances. See Envalior’s explanation of fiber orientation and thermal expansion.

Verwerkingsoverwegingen

Processing settings depend on the exact nylon and glass-filled grade. Check the supplier’s melt and mold temperature guidance, expected filling pressure and drying conditions; review gate position, fiber orientation and tool wear before production. BASF’s Ultramid molding guide explains the direction-dependent shrinkage and warpage risk.

Cost Considerations

GF30 is a useful structural comparison point, but the lowest-cost choice depends on the part, annual volume and required performance. Compare resin price together with wall thickness, cycle time, scrap, tool wear and qualification cost before choosing an unfilled or reinforced 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.

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

A material review often compares unfilled nylon directly with a 30% glass grade, although an intermediate loading may be a better fit for the part. 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.
