Food-grade PA66 FGFE5171 DuPont

PA66 has a history of 70 years since its inception. Due to its outstanding comprehensive performance, it has consistently ranked first among the five commonly used engineering plastics. Its application scope has expanded to all traditional fields that previously relied on metal materials, including automotive, electronics, industrial components, durable consumer goods, and other industries. Its use in kitchenware continues to grow.

In the early days of its use in kitchenware, PA66 primarily served as a substitute for traditional metal materials. Due to its advantages such as lightweight, ease of processing, and design flexibility, PA66 rapidly advanced the path of replacing steel with plastics. However, it soon became evident that compared to conventional metal materials, PA66 consistently exhibited shortcomings in physical properties. Its heat resistance and chemical resistance lagged significantly behind those of metal materials. Particularly during the initial phase of replacing metal materials with PA66, major companies directly applied industrial-grade PA66 brands to the kitchenware sector. Yet, when kitchenware produced from industrial-grade PA66 grades came into contact with food, various quality incidents frequently occurred, leading to prolonged consumer complaints and legal disputes. Consequently, starting in the 1980s, leading raw material manufacturers began modifying industrial-grade PA66, introducing brands that complied with food contact safety regulations. Food-grade PA66 could then be independently applied to kitchen products that come into contact with food, separate from industrial-grade PA66.

Food-grade PA66 is supplemented with two types of additives—thermal stabilizers and chemical resistance agents—to enhance the durability of kitchenware such as pot scrapers made from PA66. These additives improve the material's resistance to high temperatures and chemical exposure, including substances like cooking oil, seasonings, and detergents, ensuring the kitchenware does not degrade under high heat or suffer quality failures.

In short, food-grade PA66 and industrial-grade PA66 look identical in appearance, making no visible difference when used in kitchenware. However, their internal performance varies significantly. As a kitchenware manufacturer, it is crucial to exercise caution when selecting materials
