Brush Filament Manufacturing Process at Tai Hing Nylon Filament Products Co., Ltd.

Brush Filament that snaps after a few uses, brushes that lose shape in heat or humidity, or precision components scratched by rough filaments—these issues raise costs, invite complaints, and erode trust.

Ratefil™ PC Brush Fiber from Tai Hing was created to change that. Built on decades of material science expertise, it delivers durability, consistency, and versatility that help brush makers reduce failures and increase customer satisfaction.

Stronger for Industrial Use

The challenge: Industrial brushes often face high-frequency stress, repeated bending, and harsh chemical exposure. Conventional filaments can break, deform, or crack—leading to frequent replacements and downtime.

The solution: Ratefil™ PC Industrial Brush Filament Synthetic Fiber offers exceptional bending strength and impact resistance, maintaining stability even under heavy polishing and sweeping. Its chemical resistance ensures reliable performance in contact with acids, alkalis, alcohols, and solvents. The result? Brushes last longer, reduce replacement cycles, and cut operational costs.
