tpu waterproof and breathable membrane is used in medical disposable protective clothing waterproof strips

medical protective clothing is a type of chemical protective clothing and is mainly used by medical staff. the ideal medical protective clothing should be multi-functional. it should not only protect medical staff from toxic and harmful liquids, gases or infectious viruses and microorganisms, but also be comfortable to wear. while having barrier properties, it should also have breathable, antibacterial and hypoallergenic, and must not harm human health. in addition, the selection of protective clothing fabrics also needs to consider cost and environmental issues after disposal.

medical protective clothing is required to achieve "three resistances and one resistance", that is, water-repellent, blood-repellent, alcohol-repellent and anti-static medical protective clothing. different from ordinary woven materials, it uses special composite materials, which can be compounded by different materials. for example, with polyethylene/polypropylene spunbond nonwoven fabric is compounded with breathable microporous film or other nonwoven fabrics, or spunlace nonwoven fabric is compounded with breathable microporous film, or wood paddle is used to compound spunlace nonwoven fabric. tpu waterproof and breathable membrane is one of the non-woven materials used in medical protective clothing.

it is relatively simple to produce waterproof tpu heat sealing strips. use tpu blown film or tpu casting production equipment to make a film, and then cut it into small rolls. tpu film production equipment is very versatile, and production capacity is not a problem at all. tpu heat sealing strips can have a two-layer structure. one layer is high-temperature tpu, which provides excellent barrier properties and strength. the other layer is low-temperature hot-melt adhesive tpu, which provides excellent welding fastness and lamination speed. because the tensile strength of tpu is very high, usually up to 30 to 50 mpa, which is 5 to 6 times higher than tpr, the tpu waterproof strip does not require a plant layer at all, and its own strength is sufficient to meet the requirements of waterproofing, seepage and bacteria resistance.
