Borealis announces that it has started production of meltblown fabrics for face mask applications on its unique pilot line in Linz, Austria. Borealis has managed quickly to convert the way of working from pure development to smaller scale pilot production to regularly produce rolls of fine fibre fabrics for face masks. Recently developed by Borealis, a new proprietary polypropylene (PP) meltblown resin has boosted filtration properties due to its capability for finer fibres. By exploiting a robust network of co-operation partners in the country, Borealis is helping bolster the supply of filtration media to increase face masks production.
Responding to the Covid-19 crisis with flexibility, collaboration and innovation
A broad variety of PP based meltblown fabrics might not be visible to us, but belong to our daily lives. Such advanced PP solutions for meltblown fabrics are used not only in household appliances (e.g. vacuum cleaners), but also air cooling and heating devices. Their crucial importance for the hygiene and healthcare industries – in particular for face masks and protective wear – has been made painfully apparent as the global coronavirus pandemic has led to dramatic global shortages of essential personal protective equipment (PPE) for healthcare workers and others.
Borealis holds a 35-year track record in PP meltblown innovations and grades, and the unique pilot line in Linz has played an important role in the development. The pilot line is now being re-purposed to help meet the need for face masks. By teaming up with value chain partners, local and regional governmental organisations and non-governmental organisations (NGOs), Borealis shows its dedication to enhance health and safety of communities in which it does business. This is done by supplying filtration fabrics for face masks in order to quickly respond to an urgent need in the region. The temporarily converted small-scale pilot testing facilities are located in the Application Hall at Borealis Innovation Headquarters in Linz. The newly developed Borealis HL912FB is being used to produce meltblown fabric to be applied for customised inlays in cotton-based mouth-nose masks, for conventional mouth-nose masks, and also for high-end face masks worn by medical professionals (FFP1 to FFP3).
Unique PP meltblown resins for filtration excellence
A typical mask is made out of spunbonded outer layers and a meltblown middle layer. The spunbonded layers provide the structure while the meltblown layer is providing the barrier properties. For high-end FFP1 to FFP3 masks, more advanced meltblown structures with extremely fine fibres are essential. Borealis offers both the unique meltblown materials and a variety of spunbond PP grades.
The well-known Borealis meltblown resins HL708FB and HL712FB are reference grades for filtration. Recently, a new resin Borealis HL912FB was introduced to the market, which can be processed at higher processing temperatures allowing the production of even finer fibres. According to in-house testing, the use of Borealis HL912FB results in a significant improvement in filtration efficiency. All three grades are manufactured at Borealis facilities in Europe and made available to customers worldwide.
“The Covid-19 pandemic has led to a sudden steep increase in the need for PPE, while supply chains are being disrupted around the globe. We would like to assure our partners that we remain the reliable supplier of advanced polymers for the manufacture of high-quality face masks and other PPE,” says Lucrèce Foufopoulos, Borealis Executive Vice President Polyolefins, Innovation and Circular Economy Solutions. “True to our company purpose, ‘Life demands progress – we are re-inventing for more sustainable living’, we are offering innovative solutions like Borealis HL912FB and are re-purposing our own pilot facilities to a small-scale production line for meltblown fabrics. We have capitalised on our close collaboration with governments, NGOs and value chain partners to optimally deploy our innovation and manufacturing capabilities at the service of society.”
