On September 11, 2025, Guangdong Petrochemical's 500,000-ton/year polypropylene unit successfully trial-produced PP-HM0700 thin-walled injection molding compound. This is the company's third new polyolefin product trial-produced within a week, marking substantial progress in its pursuit of high-end, differentiated, and green technologies.
Since September 5, Guangdong Petrochemical's three units—full-density polyethylene, high-density polyethylene, and polypropylene—have successively completed trial production of three new grades of products: PE-HD5533B, PE-HD5608C, and PP-HM0700. These three products have demonstrated excellent performance in process control, product quality, and transition material control.
The 800,000-ton/year full-density polyethylene unit produced a new small hollow product, PE-HD5533B, for dairy product packaging. Due to its higher melt strength and lower odor, it successfully passed sensory and performance tests by food and beverage manufacturers and can be widely used in the filling and packaging of dairy products and beverage bottles. The PE-HD5608C cast polyethylene special material produced by the 400,000-ton/year high-density polyethylene unit fills a market gap in the Chaoshan region, effectively alleviating the high logistics costs and long delivery cycles faced by local enterprises relying on external sources. The PP-HM0700 thin-wall injection molding compound produced by the 500,000-ton/year polypropylene unit features high transparency, rapid molding, and high structural strength, and is widely used in food packaging containers, aligning with the environmentally friendly trend of lightweighting.
Behind the rapid launch of these new products lies the continuous efforts of Guangdong Petrochemical's systematic innovation mechanism, which is market-oriented, technology-supported, and collaborative. Since commencing production, the company has developed 20 high-efficiency, high-profit new material products, including three grades of metallocene polyethylene that are close to or have reached international advanced levels, high-density pipe special materials that have passed the national PE100 certification, and several film materials whose production volume is among the industry leaders. The total output of new products has exceeded 1.7 million tons, with improvements in both development speed and success rate.
