Big Hollow vs. Small Hollow Brush Filaments: What’s the Difference?

Many customers in the paintbrush filament industry often find it challenging to distinguish between big hollow and small hollow filaments. Both types are hollow filaments, but they differ significantly in characteristics, composition, and applications.

What is Big Hollow Filament?

Composition & Features:

• Primarily composed of PET material with a minor inclusion of PBT.

• Typically produced in longer lengths and later cut into shorter lengths.

• Commonly flagged (split ends) to enhance paint pickup and coverage.

Advantages:

• More cost-effective due to predominant PET composition.

• Lighter weight compared to solid filaments.

• Suitable for general-use paintbrushes that require economical pricing and lightweight handling.

What is Small Hollow Filament?

Composition & Features:

• Typically made from a PET and PBT mixture, containing a higher proportion of PBT.

• Chemically tapered to produce finer tips.

• Provides softer texture compared to big hollow filaments.

Advantages:

• Superior paint-holding capacity and smoother release performance.

• Softer and more flexible, enhancing precision in painting.

• Lighter than solid filaments but offers significantly improved painting quality compared to big hollow filaments.
