Modified nylon is a class of engineering plastics, which is a granular product formed by changing the physical properties of nylon raw material as the base material, and a granular product formed by changing the physical properties of nylon raw material as the base material. such as: reinforced nylon, toughened nylon, wear-resistant nylon, halogen-free flame retardant nylon, conductive nylon, flame retardant nylon and so on.

Modified nylon is a more common modified material at present, and the degree of adaptation of its performance and price has been unanimously recognized. however, the same modified nylon, the same new material, its quality gap may be several grades, which often cannot escape the downstream customer's "eye." If you want to make the nylon material produced better and obtain the recognition of customers, you have to start from the material selection!

There are 5 ways to distinguish the quality of modified nylon

Theoretically, the higher the viscosity of nylon slice, the higher the strength of reinforcing material, but the fluidity will become worse, and the phenomenon of overpressure injection may occur. The relative viscosity of the pure material slice is also different for different purposes.

Two, see the molecular weight distribution

For nylon spinning, the narrower the molecular weight distribution, the better the spinnability and the higher the fiber strength. However, reinforced nylon 6 is not the same, the molecular weight distribution is appropriate and broad fluidity is better, but the distribution is too wide will affect the strength and appearance.

Three, see whiteness

The whiter the pure material slice, the better the quality and appearance of reinforced nylon 6, and the higher the performance.

Four, look at the terminal amino content

The higher the injection molding product, the better the coloring performance.

Five, look at the stability of quality

The larger the size of the large factory, the more strict the management, the batch number before and after the pure material slicing is consistent, and the enhanced slice quality will be more guaranteed.

Therefore, for modified enterprises, want to improve the quality of their own modified nylon material, get the favor of downstream manufacturers, choose a reliable raw material supplier is very important!
