On February 23, Shanghai Petrochemical's emergency R&D and conversion of special melt-blown non-woven fabrics was successful in trial production.
It can produce 6 tons per day, which will help add nearly 6 million pieces of disposable medical masks per day

Meltblown cloth, commonly known as the "heart" of the mask, is the filter layer in the middle of the mask, which can filter bacteria and prevent the spread of germs.
Its fiber diameter is only one-thirtieth of the hair

After learning that meltblown cloth is still a restrictive factor for mask production, Shanghai Petrochemical gave full play to the advantages of polypropylene production capacity, technology, team and industrial chain, and immediately started urgent technical research, and cooperated with local governments and qualified manufacturers to speed up the special purpose of meltblown cloth.

"The special material for melt blown cloth is polypropylene with high melt index

In order to solve the problem of high melt index, Shanghai Petrochemical deployed its strength to set up a research and development team to carry out formula research, test analysis and scale-up experiments, and strive to overcome various difficulties such as equipment and technology, and finally successfully overcome the problem of high melt index polypropylene modified production

It is reported that through process optimization, Shanghai Petrochemical is expected to increase production by about 2 tons per day in the short term, reaching a daily output of 8 tons of special materials for meltblown cloth

In addition, since the outbreak of COVID-19, Shanghai Petrochemical has temporarily changed its production schedule, and has been working at full capacity to produce medical and health materials that are in short supply in the market.
A total of 6,776 tons of polypropylene medical materials have been supplied to the market
