Zhenhai refining and high-voltage cable sheathing pipe special material mass production

On October 23, Zhenhai Refining & Chemical Co., Ltd. successfully produced E01RS, a high-pressure cable sheathed polypropylene special material, which produced a total of about 560 tons of new products.

Zhenhai Refining and Chemical New Product R&D team found that the domestic market lacks special materials for high-voltage cable sheathing tubes. The raw materials used by users are mixed materials, which are costly and complicated to purchase. Therefore, they have formulated various performance indicators of the new products and combined them. Laboratory modification test, after nearly one year of formulation research, developed a sample of high-rigidity and low-melt impact copolymerized polypropylene resin, and passed the exploratory test of the sheath tube production line.
