Modified nylon is a type of engineering plastic, which is a granular product formed by altering the physical properties of nylon base material. This includes products like reinforced nylon, toughened nylon, wear-resistant nylon, halogen-free flame-retardant nylon, conductive nylon, and flame-retardant nylon, etc.

Modified nylon is a commonly used modified material, with its performance and price ratio gaining unanimous recognition. However, even the same modified nylon and virgin material can vary greatly in quality, a point often not missed by downstream customers' discerning eyes. To produce superior nylon materials and gain customer approval, it all starts with the selection of raw materials!

5 Tips to Differentiate Good from Bad Modified Nylon Quality

One, Look at relative viscosity

In theory, the higher the viscosity of nylon pellets, the greater the strength of the reinforcing material, but the flowability will decrease, potentially leading to over-pressure injection issues. The relative viscosity of the pure material pellets varies depending on the intended application.

Two: View Molecular Weight Distribution

For nylon spinning, a narrower molecular weight distribution results in better spinnability and higher fiber strength. However, with nylon 6, a wider molecular weight distribution actually improves flowability, but an excessively wide distribution can affect strength and appearance.

Section 3: View the Whiteness

The whiter the pure material slices, the better the quality and appearance of nylon 6, as well as its performance.

Four: View the amino acid content

Higher injection molding products exhibit better coloring performance.

Section V: Stability in Quality

As the scale of the large factory grows, the management becomes stricter. Consistency in batch numbers before and after the pure material slicing ensures that the quality of the enhanced sliced materials is more guaranteed.

Therefore, for modified material enterprises, choosing a reliable raw material supplier is crucial to improve the quality of their modified nylon material and gain the favor of downstream manufacturers!
