Leading Manufacturing

Polymerization Technology

Sinolong Industrial adopts the industry-leading polyamide polymerization technology to ensure that every customer is provided with high-quality nylon material. It has a set of mature intelligent control system which is distributed control system (DCS). The system adopts the large-scale, continuous and automatic polymerization plants. Through the intelligent control system, the company has realized the centralized process monitoring, controlling, data processing and measurement management of production. The digitalization and automatic management has reached the international advanced level.

Sinolong Industrial has built a number of flexible continuous polymerization production lines, which can produce polymers with different viscosities, and ensure that the molecular weight distribution is even, moisture content and extractable substances are low enough to reach high standards. With strict standards, we can ensure the quality of nylon materials from Sinolong to be in leading position in film grade. In the meanwhile, we can support the industrial development in spinning, engineering plastics and other fields. The production lines are differentiated to meet the increasingly diverse needs of different fields, and ensure that we can provide customers with the best quality products.

On the strength of achievements in green production, Sinolong has been recognized as a national green factory. In terms of production plant selection, process design, and controlling, it has always followed a principle which is to improve quality and efficiency, and to save energy and reduce consumption. With the high-level automation, digitalization and green production and operation management, Sinolong has released the high-quality development.
