PA66 vs. PBT: How to Choose Bristle Materials for Hairbrushes?
The hairbrush in your hand—what material are its bristles (teeth) made of? Most people never pay attention to this detail. However, for brush manufacturers, the choice of bristle material directly determines the brush's lifespan and the overall user experience. Currently, the mainstream bristle materials on the market fall into two main categories: the PA (Nylon) series and PBT (Polybutylene Terephthalate).
✂️ PA66 Nylon Bristles
The "Professional Player" in High Heat
- Heat Resistance: Melting point is above 250°C; short-term use up to 180°C.
- Performance: Can withstand the direct high heat of a hair dryer without deforming. Industry tests show it remains intact even after 30 minutes of direct blowing from a 2500W hair dryer on hot mode.
- Advantage: Exceptional bending recovery; resists fatigue and breakage from repeated brushing. Ideal for professional salons.
🌱 PBT Bristles
The "Pragmatist" for Cost-Effectiveness
- Heat Resistance: Melting point between 225-245°C; short-term use around 120°C.
- Performance: Compared to PA66, it boasts higher stiffness and lower water absorption capacity.
- Advantage: Much lower cost. It perfectly serves as a more economical and practical choice for everyday household hairbrushes and hotel disposable combs.
