On May 6, Zhenhai Refinery's No.
1 polypropylene plant used domestic high-activity catalysts for the first time, and successfully developed a new polypropylene product PPH-C03 for ultra-low ash electrical membranes, which will be used in lithium-ion battery diaphragms, capacitor membranes and other fields.
Zhenhai Refinery has taken a solid step towards high-end polypropylene products
.
This product is independently developed by Sinopec Ningbo New Materials Research Institute, independently compounded with high-efficiency additives, and independently sold
.
Compared with traditional polypropylene products, the electrical membrane material has the characteristics of ultra-low ash content
.
Ash content is an important indicator for measuring electrical membrane materials, which refers to the impurities remaining that cannot be volatilized after the product is burned at a high temperature of about 850 degrees Celsius
.
Raw materials with high ash content are prone to pressure fluctuations due to melt flow during the film formation process, which will increase the frequency of filter replacement.
Ash content also affects the actual working parameters of the capacitor film such as dielectric constant, breakdown voltage and service life

.
At this stage, domestic special materials for electrical membranes basically rely on imports and have high technical barriers
.
Ningbo New Materials Research Institute benchmarks foreign products, determines core technical indicators and technical routes, selects highly active catalysts, and optimizes the formulation of additives
.
Aiming at the difficulties of complex process control and no production experience, we worked with relevant departments of Zhenhai Refinery to jointly tackle key problems and formulate detailed production plans

This time, 42 tons of new PPH-C03 products were produced and sent to downstream users for trial feedback, providing strong support for further optimization of product quality
