Products Description

PA66, Nylon 66, also known as Polyamide 66, full name polyadipyladipamine, English polyamide 66, nylon 66, made of adipic acid and adipylamine condensation.

As the most widely used variety, PA66 appears translucent or opaque opalescence, with wear resistance, self-lubrication, high mechanical strength, high rigidity, high heat resistance, low friction coefficient, and strong impact resistance
And other excellent comprehensive performances.

In addition to maintaining strong strength and stiffness at higher temperatures, PA66 is also resistant to acid, alkali, most aqueous inorganic salts, alkanes, hydrocarbons, esters, ketones, and other corrosion, but easily soluble in phenol, formic acid, and other polar solvents.

Compared with PA6, PA66 has better performance in wear resistance, melting point, and thermal deformation temperature, but it also has higher water absorption and poor dimensional stability. The influence of hygroscopic properties on geometric stability should be fully considered in product design.

In order to improve mechanical properties, a variety of modifiers, such as glass fiber, EPDM, SBR, etc., are often added to PA66. It is relatively easy to form alloy resin, suitable compatibilizer is the key to forming tough nylon.

According to IHS statistics, 80% of the downstream PA6 is used in the civil textile field, while about 60% of PA66 is used in the engineering plastics field.

About 88% of PA66 is processed into various parts by injection molding, and about 12% is processed into corresponding products by extrusion, blow molding, etc.

High toughness Excellent anti-creep and Fatigue resistance, Low warpage

The general grade PA66 has these features and is suitable for automotive, electronic appliances, sports equipment, power tools, tool handles, high-speed rail accessories, etc.

Toughen resistance grade

Suitable for automotive parts, electronic appliances, sports equipment, power tools, high-speed rail accessories, gears, etc.

According to incomplete statistics, the global PA66 engineering plastics market scale reached 31.442 billion yuan (RMB) in 2021, and the global PA6 and PA66 market scale was 19.7592 billion yuan in 2022.

From the perspective of market change rules and market development trends during 2018-2022, the global PA6 and PA66 market scale is expected to grow at a compound annual growth rate of 6.22% during the forecast period, and will reach 283.737 billion yuan in 2028.

Since the second half of 2020, influenced by various factors, the global trade volume has declined, and the supply of the key raw material of PA66 has declined, leading to a significant increase in the import price of adiponitrile and driving the market price of PA66 in China to continue to rise.

Later, with the recovery of the overall supply, the market price showed a steady decline. By 2022, the price of PA66 in China was still relatively high compared with that before the epidemic.
