For components exposed to repeated impact or mechanical movement, toughened PA6 materials may provide an alternative to standard formulations. Impact modifiers can help improve toughness and reduce brittleness under certain operating conditions.

Other modification options include mineral filling, heat stabilization, UV resistance, and wear-resistant formulations. These approaches allow manufacturers to adjust the characteristics of engineering plastics according to specific product requirements.

By offering different material grades and customization services, Xiamen Keyuan Plastic Co., Ltd. supports customers that need more than standard polymer raw materials.

Polyamide 66 Expands the Company's Nylon Product Portfolio

In addition to Polyamide 6, Polyamide 66 is another important product category within the company's engineering plastics portfolio.

Polyamide 66, also known as Nylon 66 or PA66, is a semi-crystalline engineering thermoplastic valued for its strength, stiffness, heat resistance, and wear performance. Compared with PA6, PA66 generally offers higher melting temperature and can provide advantages in applications requiring greater thermal stability and mechanical rigidity.
