Product Introduction
The high-temperature-resistant filament is a special industrial filament raw material hot air brush , steam brushes, industrial high-temperature cleaning, and high-temperature household appliance cleaning equipment. It adopts a closed dust-free extrusion process combined with a high-temperature gradient heat setting integrated production line, along with a one-step high-temperature-resistant masterbatch modification process. The finished product has high-temperature resistance against softening, low water absorption, and the thermal stability performance of each batch is uniform.
The food-grade high-temperature-resistant filament has uniform diameter and does not soften, fall off, or release harmful substances under high-temperature conditions. It solves the problems in the brush industry where products are prone to deformation, hair loss, odor release, and frequent replacement of filaments; It is compatible with fully automatic bristle planting and winding equipment, reducing the defective rate of filament products and the cost for customers to replace consumables. The product supports standard industrial roll packaging and bundle packaging, and can directly replace ordinary PA6/PA66 conventional filaments without the need to modify the production line.

Core Product Performance Advantages
Long-lasting and stable at high temperatures, significantly superior to ordinary nylon brush filaments.
For ordinary PA66, it softens and collapses at 80℃. However, the high-temperature-resistant brush filaments of this product can work continuously for 48 hours without deformation, suitable for use with steam brushes and high-temperature cleaning machines for long-term operation.
Resistant to high temperatures and wear resistance
Friction loss in high-temperature humid and oily environments is significantly reduced, making it less prone to fraying or breaking, thereby reducing the frequency of replacement for industrial high-temperature cleaning brush filament.
Low water absorption rate, no expansion or collapse in humid and hot environments.
Under conditions of drying and steaming, or high-temperature water washing, it has low water absorption and is resistant to lodging; after long-term use, the standing angle of the brush filement remains good, and the cleaning performance is stable and does not deteriorate.
Our precision diameter control ensure a high yield rate of processed products.
The imported constant-temperature extrusion equipment can precisely control the wire diameter in real time, with a tolerance of ±6%mm. There are no problems such as material jamming or hair loss during brushing and winding. It is suitable for large-scale industrial brush production.
Four Core Production Processes
High-temperature-resistant special modified particle blending
Customized high-temperature stable masterbatch integrated co-extrusion, different from the ordinary nylon post-spraying process. The heat resistance lasts for a long time without loss. It is the core formula of high-temperature-resistant nylon filament brushing.
Constant temperature gradient extrusion stretching
Segmental temperature control extrusion, eliminating internal stress in the filament body, avoiding shrinkage deformation caused by high temperature use.
High-temperature shaping and sizing
The heat-resistant filament segmental temperature rise setting process ensures stable curing and thermal stability, with no loss of rebound performance in the 140℃ environment.
Closed-loop quality control system
Raw material high-temperature resistance test → Real-time monitoring of online temperature / filament diameter → Segmented high-temperature sampling test → Full inspection of finished products for high-temperature resistance → Shipment

Applicable Scenarios
Hairdressing industry: Hot hair brush, steam brush
The ordinary nylon brush, when exposed to 80℃ steam for a long time, is prone to bending and shedding hair, and also releases unpleasant odors. It fails the quality inspection. This modified PA66 brush hair can work continuously at 140℃ for 48 hours, and reduces wear and tear by 45%. The product uses a food-grade environmentally friendly formula. At high temperatures, no harmful substances are released, which can effectively reduce the frequency of hairdressing material replacements and lower long-term procurement costs.
Under high-temperature die-casting conditions, ordinary filament brushes will absorb water and expand, resulting in significant diameter deviations and easy material blockage during processing. In contrast, our PA46 base material can withstand temperatures ranging from 210 to 260 degrees Celsius. The filament diameter tolerance is controlled within ±6% , ensuring uniform and smooth dimensions. The hair-pulling winding process is smooth, directly reducing the production defect rate in factories.
Appliance equipment: High-temperature cooking exhaust fan cleaning brush, high-temperature brush
The ordinary material bristles will rapidly crack and age under long-term high-temperature and oil-contaminated conditions. A single material cannot be adapted to all kinds of high-temperature household appliances. This product adopts PA46 and modified PA66 as dual base materials, with the temperature resistance grade customizable as needed. It undergoes multiple levels of high-temperature shaping treatment, has a fatigue recovery rate of 70%, and is not prone to aging and cracking even when immersed in oil for a long time, making it suitable for the production of all types of high-temperature cleaning brush heads.
Automation equipment: High-temperature assembly line dust and oil removal auxiliary brushes
During continuous high-temperature production lines, the conventional filaments tend to bend and deform, resulting in a continuous deterioration of cleaning performance. Our company offers multi-gradient high-temperature-resistant customized formulas, which meet various customer order requirements in terms of hardness, fatigue recovery rate, and tensile strength, with a recovery rate of over 70%. We also provide a closed-loop quality control system, ensuring uniform thermal stability for each batch. The filaments remain upright for a long time, and the dust removal and oil removal effects of the automated production line are stable and meet the standards.
