High-grade non-woven fabrics and caps

Based on the market demand, Yangzi Petrochemical Company developed a high-end non-woven special material S2040 and a bottle cap special material YPJ706 through cooperation between the production plant and the scientific research department, and carried out trial production on industrial installations, and the batch products were put on the market.

Since 2004, Yangzi Petrochemical Company has been engaged in the research and development of non-woven special materials. Based on the relevant technical documents provided by foreign patent companies, it has independently developed and produced high melt index after digestion and absorption, process optimization and technological improvement. Spinning cloth special material product S2040. Through testing the properties of S2040 such as density, melt index, tensile strength and elongation at break, all performance indicators have reached the required standards, and they can completely replace imported materials, filling the domestic gap. At present, the high melt index non-woven fabric special material S2040 passed the technical appraisal.

Polypropylene cap special materials have high melt index, high molecular weight distribution, and difficult process control. Through technical cooperation between the plastics factory and the research institute, several technical exchanges have been made, and caps suitable for the characteristics of polypropylene production equipment have been developed. The special material production plan, on the 200,000 t/a polypropylene production plant, successfully uses the copolymerization production process to develop and produce a special material for polypropylene cap YPJ706. The product performance meets the requirements and can be widely used in soft drink bottle caps and household appliance parts. The production and production of the bottle cap special material YPJ706 was successful, creating a precedent for the domestic use of the copolymerization method to produce special materials for caps.
