China professional Manufacturer, Supplier, Factory

At present, the intelligent power grid project is flourishing, and the construction of distributed power stations is also vigorously promoted, which puts forward higher requirements for the electrical safety performance of high-voltage cable joints. The original conventional coating materials can no longer meet the higher performance requirements of flame retardancy and voltage breakdown resistance.

They have a wide range of applications and can be made into various furniture items in daily life. Moreover, not only do they have an elegant appearance, but they are also sturdy and durable, making them an ideal choice for furniture and daily use. This is exactly where the charm of the rotomolding marble particle material lies!

​On May 16, 2025, our company participated in the "China Plastics Association Rolling Plastic Special Committee 2025 Annual Meeting" held in Xingtai, Hebei Province.
