Brushes with high-temperature resistance possess excellent heat resistance and superior thermal deformation temperature, making them widely applicable in fields with long-term exposure to high temperatures and heat. Among the materials used for heat-resistant brush filaments, PA66 and PA46 are the most commonly used types of nylon filaments. Many customers are torn between these two options when choosing heat-resistant filaments.
The melting point of PA66 nylon filament is around 250°C. Compared to other nylon filaments, it has a more advantageous thermal deformation temperature and is suitable for fields with high requirements for heat resistance and fatigue strength, such as salon combs and steam iron brushes. On the other hand, PA46 filament not only has better temperature resistance and thermal deformation temperature than PA66, with a melting point of about 295°C, but it also excels in toughness and wear resistance. It maintains excellent mechanical properties and outstanding wear resistance under high-temperature conditions.
The PA66 or PA46 nylon filaments used by FIFO are made from brand new, pure material filaments, without any first-time or multiple recycled materials, ensuring quality.
