Polyamide Glass fiber Plastic materials Nylon PA66

Nylon PA can be divided into: general grade, reinforced grade, injection molding grade, extrusion grade, etc.; PA66+LGF long glass fiber is our own brand of self-production and sales; the sold PA6+LGF has stable performance due to its complete variety. Affordable, has been widely recognized by domestic and foreign customers.

The high molecular weight polymer of the amide gene in the nylon PA66 macromolecular chain can reach dozens of nylon varieties. The density of nylon PA is generally 1.0-1.01g/cm3, and the crystallinity is 40%. 60%, the average molecular weight is 20,000-70,000. Nylon PA is a kind of linear polymer. If the nylon PA is resistant to high temperature up to 200 degrees, it can be used as a heating material for mechanical heating. Nylon PA has a high probability of water absorption and expands in volume after water absorption, which leads to a decrease in the precision of nylon PA size products. Nylon PA66 will decrease in water absorption rate as its own hydrophobic gene increases, while PA1010 has a water absorption probability of 0.39%. , PA1 is 0.25%. Most of nylon PA is tough, non-toxic, tasteless, and even produces a burning charcoal when burned. Nylon PA66 has a high melting point and strong crystallinity. The melting temperature of nylon PA is mostly 200 °C. Above, the oil resistance is better, and it can resist general solvents. Nylon PA66+LGF has excellent mechanical properties, and can be superior to general plastics in tensile strength and impact strength, and has high bending fatigue strength.After PA66is reinforced by glass fiber, its heat distortion temperature reaches 250 degrees.

Nylon PA66 also has good self-lubricating and wear resistance. Nylon PA can be stable to acid, alkali and salt, oil and solvent resistant, and nylon PA is much better than PE and PP. Printing performance can be maintained without static electricity. Compared with other thermoplastics, nylon PA66 has a softening temperature range and a relatively obvious melting point.
