Main Products:-


1.Nylon Filament

Nylon filament products are divided into six kinds according to the raw materials: Nylon 6, Nylon 66, Nylon 610, Nylon 612 ( Producing by the Chinese raw materials) , Nylon 612 ( Producing with US DuPont Zytel raw materials) and nylon 46 filament. The “DAMI”brand nylon filament is one of the superfine filament of our company.It has excellence mechanical performance, resisting assault, hard surface, wear-resisting.Low temperature performance and chemical stability is good.


2.PP Filament

PP monofilament is one of the lightest product in all filament at present, and the price is relatively cheap. It has good mechanics performance,low absorbency and good chemical stability.Besides it can be corroded by thick sulfuric acid and thick nitric acid, it is steadier to other chemical auxiliary. So PP filament is suitable for processing various cleaning brushes.


3.PBT Filament

PBT filament has excellent performance of toughness,resisting tiredness and shock. And its heat-resisting performance, climate-resisting performance, electric performance and bearing electric performance are good. Because of its moisture rate is low, it’s very suitable for processing the brushes which are working in the wet environment.


4.PET Filament

PET filament have the strongest toughness.It’s able to bear creep, resisting tiredness and friction. Its resisting chemical medicines ability and heat-resisting is good. It can be used in the temperature to reach 120°C for a long time, keeping good physical mechanical performance within the range of wider temperature.


5.PVC Filament

PVC filament's fire-retardant and chemical stability is good. It also can resist acid and alkali. And further, it has good soft and flagable performance,so it’s suitable for processing the wash car brush, industrial brush and brooms.


6.PS Filament

PS filament has higher rigidity, surface hardness and glossiness.It also can resist acid and alkali.So it's very suitable for processing the wash car brush and industrial brush,etc.Specially for processing the adornment of the Christmas tree.


7.PE Filament

PE filament has higher rigidity and toughness performance.Its resisting assault, cold-resistant performance and chemical stability is very good. It’s suitable for processing the wash car brush and house cleaning brush,etc.


8.PEEK Filament

PEEK filament is one kind of filament with good synthetic performance, heat-resisting,resisting tiredness, wear-resisting and workload.It also has excellent fire-retardant performance,self-snuff out perfomance,resisting irradiation and resisting hot oxidation performance.PEEK filament is steady to other solvents except dissolving into thick sulfuric acid and nitric acid,it will turn yellow. Generally it's used for processing high-class hair comb or industrial use,etc.


9.PPS Filament

PPS filament has good resisting creep perfromance,hot stability, wear-resisting, fire-retardant,self- snuff out perfomance and chemical stability.It’s able to bear sparse acid and alkali.PPS filament is generally used for industry.
