What are the advantages of PBT Non-tapered filament for toothbrush applications?
BrushMake's PBT (Polybutylene Terephthalate) Non-tapered filament is valued for its extreme durability and stability in toothbrush manufacturing:
Exceptional Abrasion Resistance: Superior to most nylons, PBT bristles are highly resistant to wear from brushing and toothpaste, maintaining their effectiveness over time.
Excellent Color Fastness: PBT has outstanding resistance to fading, even when exposed to colorful foods, drinks, or mouthwashes. This ensures the toothbrush retains its vibrant colors throughout its use.
Very Low Moisture Absorption: Similar to PA612, it absorbs minimal water, promoting fast drying and enhanced hygiene.
Firm Stiffness: Non-tapered PBT filaments provide a firm and consistent cleaning action, preferred by users who enjoy a vigorous brush or for specific cleaning needs.
This filament is commonly used for firm-bristled toothbrushes, travel brushes, and brushes where maximum color retention is a priority.
