Recently, LZSH Petrochemical Technology Group has successfully developed a heat-resistant polypropylene special material for household appliances, which has successfully realized the replacement of imported heat-resistant polypropylene for household appliances.
Heat-resistant polypropylene is used in heat-resistant home appliances, automobiles and other fields due to its high heat distortion temperature, good gloss, high flexural modulus and high impact strength. However, the heat-resistant polypropylene special materials required by China's small home appliance industry have long been monopolized by foreign companies.
For this reason, LZSH focused on the problems of unsatisfactory impact performance, low cost performance, and high user cost of imported heat-resistant polypropylene special materials for home appliances, and concentrated its efforts on targeted technical research. Through 5 years of independent innovation, researchers have found a new technical route. According to the theory of coordination polymerization, through the design of a special catalyst system, combined with reaction zone control technology, they have developed a complete set of production technology combined with the LZSH production device. Realize the control of product structure and performance. They also pioneered a cost-effective dual-function compound nucleating agent, which enables the domestic home appliance heat-resistant polypropylene special material to achieve a better balance of rigidity and toughness than imported materials.
In order to make domestic home appliances heat-resistant polypropylene special materials able to enter the international market, LZSH has successively obtained domestic CQC certification and American UL certification, making heat-resistant polypropylene special materials for household appliances the first to enter the domestic high-end polypropylene market.
"The heat-resistant polypropylene special materials produced by LZSH have unique advantages in terms of melt index, modulus, rigidity and toughness balance and other indicators and performance. We plan to use 3 years to make the Chinese market share of heat-resistant polypropylene special materials exceed 30%, so as to promote the leapfrog development of LZSH polypropylene business.” said Gao Yulin, chief of the production technology section of the Lanzhou Petrochemical Polypropylene Plant.
